Congratulations to Jenifer!!!
VIPs are good for PhDs
After a long journey, last Thursday, my PhD student Jenifer Rachel from the IMPRS Neuroscience program finally defended her thesis work in a very successful manner. It turned out that VIP neurons still have the potential to make a VIP out of a student ;-)Congratulations to Jenifer!!!
And a big thanks to Martin as her direct supervisor and everybody who prepared some food and drinks! Unfortunately, our webpage does not allow for pictures anymore but just to tell, the cakes looked great.

If Pasko Rakic says this about your research, the only reaction can be SMILE
Thank you for submitting your work to Cerebral Cortex and congratulations! It is not easy to get a manuscript accepted in our journal these days, since due to the large number of submissions, we can accept only a small number of exceptional papers and yours is in this elite group.Congratulations to Julien and Amouk for making this happen :-) :-) :-)

It is also a little bit our work (in the future)
All of us in Neuroanatomy have a "previous life", which is (of course) always interesting. In this case also scientifically since Xiaoyi (Mao) has just published her BSC thesis work that she has performed back in China. Like it or not, Chinese neuroscience has really advanced to an impressive level and thus publishing in the journal of the national society means something.
From all I can judge this is very good work on multimodal classification of layer V neurons in primary cortical areas of the mouse using Patch-PCR. Their final conclusion is up to the point (and unfortunately something that was as unwanted as in all the comparable studies like for instance Gouwens et al.): "Our study reveals the presence of substantial M/E variations
in cortical interneuron populations defined by molecularexpression." Here is the link:https://link.springer.com/article/10.1007/s12264-022-00983-x
Congrats, Xiaoyi!

When it gets cold in Germany hot Indian food could be a remedy
As the pandemic slowly fades out, we could afford going out for dinner as a Christmas party. Again, we were in good luck since the temperatures were some 20 degrees lower than the last two years (in which we celebrated outside). So, we had a relaxed evening at an Indian restaurant where we could enjoy 4 different curries and some flavor-rich dessert. Thank you for joining and keeping up our spirits.

Manuscript accepted at Cell Reports
I am very happy to announce that after a substantial revision in a fair review process, our manuscript on 2-photon-targeted patch clamp recordings of GABAergic neurons in the barrel cortex has been accepted. It clearly shows a substantial direction selectivity of VIP neurons in L2/3, similar to pyramidal cells. In contrast, many SST cells display direction-selective inihibitory inputs, which we speculate to be an in vivo correlate of the disinhibitory VIP-to-SST connectivity, well known from slice physiology. Furthermore, in a good agreement with previous literature, PV cells do not show direction sensitivity after ramp-and-hold whisker deflections.Well done and congrats Julien, and thanks for your support Martin!

Neuroscience 2022, welcome back to San Diego
After an in-presence pause of 2 years, some 20000 neuroscientists dared to gather in larger and smaller rooms to celebrate science. Yes, the drop in participants could be felt by less dense schedules and less long queues at Starbucks. But nevertheless, talks by Ardem Patapoutian, Viviana Gradinaru or Hongkui Zeng were precious highlights and the many great posters stimulating as always. Let's not start talking about what the Allen Institute has achieved ...See you in Washington next year!

Neuronex “Working memory” on the beach
In the third year of its existence, it was finally possible to meet in person. Well, the transfer from virtual to reality worked pretty good and we had quite some fun, in addition to exciting science while having the beach of La Jolla right in front our eyes. After a status update by every IRG, we were discussing how to proceed to strengthen our cooperations and move forward to common publications. A bonfire on the beach, with plenty of local beers, wrapped up an entirely successful meeting.

Barrels 35 – back in presence!
Barrels 35 was well visited by some 90 researchers from all over the world. Meeting at the Hilton in La Jolla, we saw 2 days of exciting science that were crowned by the keynote speakers Lauren Orefice and Karel Svoboda. My personal highlights were Carl Petersen with “Neuronal circuits for goal directed sensorimotor learning”, Tomaso Fellin with “Contribution of different sensory modalities to texture discrimination in mice” (In the latter, we learned that mice can do it all just by olfactory cues) and Takaki Komiyama with motor learning and recall by holographic optical stimulation. Unfortunately, I missed day 2 because of other obligations. See you again next year in Baltimore, Barrels crowd.

SFB/CRC 889: a joyful 12 years research consortium comes to an end
On the 01./02.11.2022 the final symposium of the SFB/CRC889 took place at the "Alte Mensa" in Göttingen. This CRC was a success story that was celebrated with invited talks and "wrap--up" talks of all contributing PIs.My personal favorite was Fritjof Helmchen's talk on how elegantly the whisker system of the mouse serves as a model system to study tactile learning at brain-wide, local and subcellular levels. But also Alexander Heimel's talk on escape behavior versus novelty seeking in rodents offered fascinating insights to what superior colliculus and zona incerta can do in this respect.
At the far end, for me remains only to say "THANKS" to Tobias, his support crew. all colleagues and my PhD students, postdocs and technicians who contributed to this success story over the years.

When a simple thing like the acceptance of a frontiers paper brings a lot of joy ...
... then this means that there is a history.And in this case there is a long and multifacetted history behind the paper that, for reasons that were not in our hands, dates long back, even back to Freiburg times. Never mind, good quality data stands the test of time and so this is something to be proud of:

Berlin conference - reprise
Not everything in Berlin does not work ;-)The Anatomische Gesellschaft Tagung was pretty well organized and fun to participate. Thank you Imre, Viktor and Matthias (and everybody else).
2022-09-26
116th meeting of the Anatomische Gesellschaft in Berlin
Berlin called and approximately 350 anatomists came to participate in the conference. In the "ehrwürdige Gemäuer" of the "Wilhelm-Waldeyer-Haus", in the shadows of the Charité building, we saw some remarkable keynote lectures (e.g. Zoltan Molnar) and scientific sessions (e.g. Neuroanatomy, with Merve). In the poster session, Flore and Mirko presented a very appealing poster on "intersectional" VIP cell types. Thus, our institute was well represented.Thank you very much Merve, Flore and Mirko for your contributions!

Business trip 2022: when hot guys defy the hot wheather
We were always lucky with our business trips, not only but not the least for the wheather. So, no suprise that in these days it was better than good. Never mind, it was all fascinating in Bad Sooden (seeing Allendorf only from afar) and we learned a lot about salt. We furthered our senses on the barefoot path on the Hohe Meissner mountain (at a lush 29 degree Celsius) and then wanted to jump into the cold waters of Werratalstausee. But the water was NOT cold. It more felt like a bath tub. Anyway, altogether it was big fun. Thank you organizers, job well done!

Lausanne Barrels Meeting and VIPs
A short note on our own account: the talk about VIP neurons was well received and stimulated a lot of discussion, mainly towards the "exciting" idea that they may release GABA, acetylcholine and VIP to cause multiple effects in target cells. What a pity that Huib Mansvelder decided to talk about intelligence (and the brain) instead of about VIP subtypes' connectivity. It seems most discoveries on the cell types still need to be made ... .

Fantastic conference at a fantastic location
After a delay of 2 years, due to (guess) ..., the Barrels community met in Lausanne to celebrate the 50th anniversary of barrel cortex discovery with the first live conference after the pandemic (and at least in Switzerland no sign of it ever having existed was apparent). It was a feast of science and great hospitality by the main organizer Carl Petersen and his team at the EPFL.Well, there were so many terrific talks that naming anyone and not mentioning other seems like heresy. From the start by a trio uncovering the the whisking CPG in unprecedented detail (Kleinfeld/Wang/Golomb) to the end by Josh Huang who marveled us with a motor command story in the higher order motor cortex for eating, no presentation disappointed - also not the student ones!
Don't miss the next chance to be there yourself!

Pink phase is over ...
Hooray, we have a new group picture (as you can see on the landing page)!The pink phase (dictated by the pandemic) is over and merges into a green phase (which gives a lot of hope for better times to come). Of course it was also necessary because of the dynamics in the group, which saw several former group members leave while new ones arrived.
Best of luck to all former, present and future ones ;-)

NEURONEX reprise
Since the virtual world obviously has its limits when it comes to discussing data in detail, the chance to meet with Neuronexers from London (Ontario) in Göttingen was a very fruitful opportunity at which we learned how nicely comparable and also complementary our data on marmoset patch clamp electrophysiology is. This adds momentum to the project, which certainly will present more challenges to be met. Nevertheless, the first steps towards an exciting goal are made.
2022-05-10
Update on NEURONEX
Certainly it is a big challenge to start an international consortium during a pandemic. Nevertheless, due to the high committment of all participating PIs and group members, we have been able to create substantial progress that is about to be reported soon. For IRG2 in Göttingen this means that some 150 neurons were successfully recorded, preferentially in marmoset prefrontal cortex. This was only possible due to the invaluable support of Prof. Hinkel and Dr. Mietsch from the German Primate Center.For those who are interested to learn more about Neuronex, please check out:
https://www.nxwm.io/
In its final state, our data will be integrated into a database that has been taking great shape recently:

As times go by ...
young medical students become young doctors. In this case, Simon Badura finally earned his MD degree, after having done his work at our lab in 2014/15. Nevertheless he could convince us with his performance at today's thesis defence.The title of his dissertation is: GABA-B-Rezeptor-vermittelte Modulation an Martinotti-Zellen im primär somatosensorischen (Barrel) Kortex der Maus
Congratulations to you Simon - and many thanks to his direct supervisor Mirko Witte.

Succeeding under pandemic conditions
What is this? Professors wearing face masks, students wearing face masks, colleagues wearing face masks, audience being largely on Zoom, no party allowed? Well, of course, it is a thesis defense in year 2 of COVID19.That this can be successful, and a little bit of fun, was proven by my PhD student Anouk Meeuwissen who passed her "final exam" on WED 17th of November in the SMN branch of the GGNB. Congratulations!
A special thanks goes to her direct supervisor, Julien Guy, who was instrumental for this success.

Is good luck twice already a lucky streak :-)
This is always very good news - manuscripts being accepted and getting on the way of becoming a "paper". Papers are forever and this is why they should be good (at least). I am pretty sure this is what we have achieved in two collaborative projects:1. With Andreas Neef's group: "Theta activity
paradoxically boosts gamma and ripple frequency sensitivity in prefrontal
interneurons" has been accepted for publication in PNAS. This manuscript shows the exquisite sensitivity of adapting GABAergic interneurons (putative SST neurons) in mouse prefrontal cortex to different statistical properties of input frequencies as measured by dynamic clamp.
2. With Bruno Cauli's group: "Lactate is an energy
substrate for rodent cortical neurons and enhances their firing activity",
has been accepted for publication in eLife. This manuscript shows that lactate is an important energy substrate and its
metabolism shapes neuronal activity in the rodent somatosensory neocortex
through KATP channels.
Watch out for these papers getting published!

When the best is not possible, second best has to do the job
From 03.-05.11.2021, BARRELS XXXIV was held another time online. Shall we be happy or sad?Well, of course we should be happy that with Zoom, and all the possibilities for virtual interaction, it really feels like a good scientific exchange. But of course all socializations aren't that easy, especially when you basically span all global time zones.
So, the organizers (and here I mean especially, Robert, Randy and Drew) did a great job, as did the symposium organizers and speakers as well as all of the some 150 participants.
Hope to see you next year in Lausanne first and then whereever the SfN will lead us to.

A new medical doctor was born
After having accomplished several other milestones in life, Lisa Tohermes (formerly Thieke) successfully defended her MD thesis entitled "Nachweis der Expression metabotroper GABA-B-Rezeptoren in GABAergen Interneuronen des somatosensorischen Kortex mittels Immunhistochemie".As so often, this would have not happened without Mirko serving as her direct supervisor. So thanks Mirko and Lisa for that

The 115th Annual Meeting of the Anatomical Society happens right now
And probably not too many people do notice :-(Well, as so many conferences, this one -supposed to take place in Innsbruck- had to be shifted into the virtual realm. But why did it have to be organized as a webinar? Anyway, I am happy that we will have two high-class contributions:
1.) Mirko will talk about neuromodulatory effects of GABA-B-receptors on fast inhibitory synaptic transmission showcasing the work of his talented medical students
2.) Felix presents a poster on disinhibitory circuit motifs, in which translaminar VIP-to-SST connections are studied with paired whole cell recordings.
Good luck, guys (meaning an active and attractive audience ;-)

New Insight into Serotonergic Neuromodulation on Striatal Synapses
Published yesterday in Journal of Neuroscience, a paper from the "previous life" of our Neuronex-postdoc Stefan Pommer, provides compelling evidence that 5HT acts via 5HT1b-receptors to modulate lateral inhibition by striatal spiny projection neurons (also called medium-sized spiny neurons) via presynaptic transmitter release reduction.

Successful thesis defense by Pauline
What an intense and successful journey!On Monday, 23rd of August, Pauline successfully defended her thesis entitled " Molecular mechanisms underlying cortical (mal)formation: case studies of ESCO2 and EXOSC10"
I won't tell you what is behind these acronyms but the moelcules come from vastly different worlds. Nevertheless, when you knock them out, the phenotypes have a lot of commonalities. If you want to know more, check out at our "Publications" page. Certainly, we will hear more form Pauline, not only bcause she will continue her research with Tran Tuoc's group in Bochum.
CONGRATULATIONS, Pauline - and thanks to all people in the lab who supported her on her "final day in Göttingen".

Successful collaboration in CRC 889
Running in its 10th year, the CRC 889 enabled another successful collaboration with the Loewel and Schlüter labs! In a meticulous effort, PhD Student Rashad Yusifov managed to perform in vivo-2P spine imaging in V1 under monocular deprivation in PSD95-knock out mice after sparsely labeling L2/3 pyramidal cells with in-utero electroporation.This study was now published in PNAS: "Spine dynamics of PSD-95-deficient neurons in the

A good scientific start into the New Year
So now it's 2021! Of course there are more important things these days than a new paper being published. Nevertheless, while we all wait for a vaccine to bring more normality in our lives, it is also spirit-lifting to see a great publication on which we have been working so many years now "in print". In a way, 2021 can become a good year.Thanks again to Nora and Maren for making this nice piece of science happening!

How to get a new group picture?
2020 brought so many changes, not the least COVID-19 that for the moment promises to stay with us for a while. Since a lot of people left our group in 2020 and many new ones joined, it was high time to update our group picture. But how to do that under the current circumstances? Well, Santa Claus helped us with an idea that you can see on our loading page! Have fun with identifying all the new and old group members. Thanks everybody for making this happen!

50 years of barrel cortex reloaded
As 2020 comes to an end -and the planned conference in Lausanne has been shifted to next year- I would like to take this opportunity to make you aware that our review (with a biased view of course) on this exciting research period has now been published in its final form in Physiological Reviews. Please check out:https://journals.physiology.org/doi/full/10.1152/physrev.00019.2019.

Was gar nicht so lange währte ..., wurde am Ende noch besser
Doktorarbeiten erfolgreich abzuschließen ist immer etwas besonderes. Dieses Mal hat es Kristina Glöckner zum Dr. med. dent. geschafft, nachdem sie am 10.12.2020 ihre Arbeit Elektrophysiologische Charakterisierung von GABA-Rezeptor-vermittelter Inhibition an Martinotti-Zellen der Schicht 5 im Barrel-Kortex erfolgreich verteidigt hat.Herzlichen Glückwunsch und auch vielen Dank an Alle, die das ermöglicht haben!
P.S.: Der private Besuch der Gänseliesel erfolgte mit einem ausgeklügelten Hygienekonzept ;-)

Nature Neuroscience comment published
Sometimes the devil is in the details, many of which were fixed on the way to publication. Except for one, the typo in a name, my name. It is strange how much a single exchanged letter can change the appeal of something. Steiger is not the same as Staiger, usually. But as you can see on our Publications page, yes it is an original contribution from us to an effort of the community, in order to achieve a future common nomenclature for cortical cell types. I hope you find it helpful (it is open access)!https://www.nature.com/articles/s41593-020-0685-8

How plastic can an axon initial segment be?
Pretty much!As a very pretty paper that was just accepted at Nature Communications will soon show the world ;-)
In this cooperation with Maren Engelhard, we were able to show for the barrel cortex that acute stimulation or deprivation of whisker-dependent tactile inputs leads to the rapid homeostatic plasticity in AIS of excitatory neurons in the corresponding barrel-related columns. Watch out to read more in
"Sensory input drives
rapid homeostatic scaling of the axon initial segment in mouse barrel
cortex" by Nora Jamann, Dominik Dannehl, Nadja Lehmann, Robin Wagener,

Another Scientific Reports manuscript accepted
It always feels good when long-standing collaborations come to a successful end. In this case it was one with Werner Kilb from Heiko Luhmann's group in Mainz on "NKCC-1 mediated Cl- uptake in immature CA3 pyramidal neurons is sufficient to compensate phasic GABAergic inputs". This manuscript has just been accepted at Scientific Reports.Congratulations!

POM again
A couple of years after Alvar's first paper made it first as the Paper of the Month (POM) and finally even as the Paper of the Year in 2016, I now have the pleasure to announce that Xiaojuan's recent publication also made it POM in February 2020. This is well deserved since she achieved to combine a high level of insightful data on GIN cells with a beautiful illustration of their microscopic and ultrastructural features. Congratulations!https://anatomische-gesellschaft.de/?post=gewinner-der-paper-of-the-month-in-2020

All good things have to come to an end
After working for approximately 7 years at the Institute for Neuroanatomy as an independent junior research group leader, Tran Tuoc has found a permanent position at the University of Bochum (Dept. of Human Genetics). With him, also Linh and Godwin have moved, thus leaving Eman, Pauline and Xiaoyi here, in order to finish their projects. Thus our interactions will remain productive for the next couple of years.Best of luck at your new scientific home, Tran et al :-)

Why is science always happening in waves?
After sailing for quite some time in a wave trough, it seems that the lab has now reached the crown of another wave of publications.It felt totally awesome to see the Phyiological Reviews paper being published online ahead of print. It was also heart lifting to see the online version of a community effort on cell type classification being posted on the Nature Neuroscience server.
Furthermore, tonight the good news reached us that Georg's second PhD project had been accepted by Cerebral Cortex, after having reached quite some views on the preprint server. If you are curious, here is the link to BioRxiv.

Review manuscript published ahead of print
There are easier and there are harder achievements. This was a very hard one due to many reasons. But as it is probably often the case after deliveries, soon the pain if forgotten and the joy remains. Also in the case of this Physiological Reviews paper, which was finally accepted recently and now is available online ahead of print. Together with Carl Petersen, we covered 50 years of barrel cortex research on whisker-based sensory perception and the underlying cell types and circuits. Let's hope that the community likes this kind of encyclopedic ressource.Please check out:

Update on: Celebrate 50 years of barrel cortex research with us
Dear Barrels afficionados,due to the Corona crisis and the associated travel regulations, we have decided to postpone the meeting to next year. Please find the new date and according information here:
2020-04-21
Corona takes its toll on conferences
Recently, some conference organizers took action and did the expectable: they either shifted their conference in to the next year (e.g. Lausanne - 50 years of barrel cortex) or venture the virtual realm (FENS Forum "in Glasgow"). Also the Barrels 33 meeting, supposed to be scheduled right before the Neuroscience 2020 conference in Baltimore, will happen in the digital world, in a format still to be designed, since a time zone of 10 hours needs to be respected.What a pity! So many missed fruitful and pleasant personal interactions.
2020-04-08
Corona and science
The news blog was sparse in recent times. Not that there had been nothing happening, it was just the rush to keep up with the latest Corona developments (and their consequences for work) that kept us busy.There is good news and bad news (as always ;-). The good news is that an opinion paper on cell types and their putative nomenclature was accepted at Nature Neuroscience. This brings a fruitful conference (The Brain Conferences - The necessity of cell types for brain function, Copenhagen October 2018) to an even more rewarding end.
The bad news is that the FENS forum in Glasgow will be held as a virtual conference. This is bad because it is the human touch that makes conferences of this kind special. But of course, not all the conferences of the year 2020 can be shifted into the future, conference schedules are already tight throughout the year.
Take care and stay healthy!

Second helping
... and there was a second table at the Kartoffelhaus, unfortunately it was too long to get everybody on the picture.

Oh, is it already Christmas again?
Another message that is not twittered out to the world: we already had our Christmas party! Well, already is not the right expression since Christmas seems to be just around the corner - and we also brought the first tree ever into our building. As you can see, we had a nice dinner in a cosy restaurant and played some "relaxing" games (no drinking ones ;-) that Mirko prepared for us. It was a pleasant end for a pleasant year.
2019-12-13
This time it is eLIFE
Hooray, together with the group of Carl Petersen at the EPFL, Michael, Pavel and me could contribute to a study named "Pathway-, layer-and cell-type-specific thalamic input to mouse barrel cortex". As the title says, it is a pretty comprehensive optogenetic mapping of inputs from the VPM and POm on all kinds of target cells in the barrel cortex.Watch out for it getting "printed"!
2019-12-10
More doctors for the world
In the big rush of this year, 3 new "doctors" have been delivered to the world by us.These are- Godwin Sokpor "Cortical patterning and neuronal migration are under the guide of BAF complex functionality"
- Michael Feyerabend "Thalamocortical innervation of GABAergic interneurons in mouse primary somatosensory vibrissal cortex"
- Christina Bachmann "Loss of BAF 155 impairs neurogenesis in the developing olfactory system of mice"
A BIG thank you for all your efforts to make this a success and of course to everbody else who helped on the way!

Another manuscript accepted
I am happy to announce that another manuscript has been accepted in late 2019!It is a collaboration with Robyn Grant that stems from her times being a postdoc in Tony Prescotts lab. Here, we present a first description of quantitative parameters of reeler mice whisking. In short: they are much more normal than anything else! Watch out for the publication to get printed.
2019-11-05
Cerebral Cortex paper now Online
In a cooperation with Bianca Brunne and the late Michael Frotscher, we contributed some data on cortical layering in mice, which got their reelin gene knocked-out specifically in GABAergic neurons. This was achieved by corssing a floxed reelin mouse with a Dlx 5/6 cre-driver line. The results show suprsingly mild effects, mainly on dentate gyrus features.If you want to learn more, it's open access:

Cool conference at a cool place
So long to prepare, so quickly being over: Barrels XXXII is already history. A great one, though! Not only the session with Julien, Chinfei, Dan and Gavin was very insightful. Also the social behavior (singing mice, helping, rats, gambling monkeys and incest blocking brain areas) and the cerebellum talks were simply enlightening. The local organizing committee did a great job (thanks to Gordon), too. We will come back!

Cell Reports paper published
We have been waiting for this moment for a long time! After starting with rabies tracing in 2013 and finding out later that most viral vectors have a substantial amount of TVA leak expression, we are very pround that we were able to control this problem to the best possible extent. We were also lucky that in the meantime intersectional viral vectors were introduced so that we could clean up the PV cell population from the 10 % of pyramidal cells in L5 that do express PV. Congratulation and thanks to Georg for not giving up!

Wüzburg meeting of the Anatomische Gesellschaft
The final program of the 114th Annual Meeting of the Anatomische Gesellschaft (25.-27.09.2019) is published and we are looking very much forward to contributing 2 talks on GABAergic neurons in the reeler cortex. Julien and Georg will present their latest results on sensory processing and connectivity of mainly VIP neurons in the mutant and in wild type controls.

Fantastic: another manuscript accepted!
What a great day: Georg's manuscript at Cell Reports has been accepted after a long and extensive revision. Whatever, the study got even better and the reviewers were very pleased! I am really proud that after all the troubles we had to face with the method, we could finally come up with this:Mapping the brain-wide afferent inputs of parvalbumin-expressing GABAergic neurons in barrel cortex reveals local and long-range circuit motifs

Manuscript finally accepted
We are very happy to announce that the Journal of Comparative Neurology has accepted a manuscript, which was mainly prepared by Xiaojuan and thus can be regarded as a "farewell present" by her! It is entitledCharacterizing the
morphology of somatostatin-expressing interneurons and their synaptic
innervation pattern in the barrel cortex of the GIN mouse
Xiaojuan Zhou1, Ima Mansori1, Tatjana Fischer1,
Mirko Witte1, Jochen F. Staiger1
In this paper we describe the synaptology of the GIN cells, which are by and large Martinotti cells and innervate small, non-GABAergic dendrites.

Convocation of the Glorious Three
On a very special day for our lab, 3 PhD students at once were going through the sequence of convocation ceremony, kissing Gänseliesel and doing some heavy partying. No doubt, all three of them certainly deserved the special attendance that they got. Congratulations to Huong, Kamila and Georg and many thanks to the people who worked hard to make this day a success!

Business trip 2019: wet from above and wet from below
On Wednesday, 19th of June, we went out for our yearly trip to a location well appreciated by us: the Hofgut Stammen. After a long canoe trip on the Diemel with lots of fun above and below the water, we had farmers games (including milking cows), barbecue and beach volleyball and a "little" thunderstorm. Never mind, in our ninth year, we had nine times the best wheather you can wish for.
2019-04-26
Manuscript finally accepted
What a struggle! After 3 rounds of review and satisfying probably 6 different reviewers, we finally made it again into Cerebral Cortex.
Neuromodulation leads to a burst-tonic switch in a
subset of VIP neurons in mouse primary somatosensory (barrel) cortex
the work by Alvar, Martin and Mirko that created so much excitement during the last 2 years, has finally a home to be proud of.
Congratulations for an excellent piece of work!
2019-04-25
New publication
After having had 5 manuscripts in revision, with 3 more being reviewed, surely this second accepted paper of the year will not be the last one. Funnily, the manuscript just accepted was the last one submitted. Let's hope that the scientific community will consider it small but beautiful (helpful), Thanks to Zsuzsa, Csaba and Mirko for keeping the faith!

Göttingen meeting of the German Neuroscience Society
As every other year, the "Neurowissenschaftliche Gesellschaft" held its Göttingen meeting in Göttingen - as you might have already guessed. This time in its 13th occasion, great neuroscience from all over the world was sponsored, with remarkable plenary lectures on soccer/football, consciousness, smart birds, stunning bats and time machines. Somewhat out of season for us, we only had a very interesting poster on epigenetic regulation of forebrain oligodendrocyte development presented by Eman Abbas.

Christmas party 2018
As our ninth year in Göttingen comes to an end, several pleasant traditions have evolved, one of these being our Christmas party. This year we warmed up at the Bowling center that usually sees relaxed Neuroanatomy members that play for fun in the first place. Everybody scored! Afterwards, of course, everybody was hungry, so the carnivor orgy at the restaurant "Argentina Steakhouse" came in handy. Keep your spirits up, guys!

A new doctor has been born
After a quite prolonged "pregnancy" and some hard episodes during "delivery", a new doctor (med. dent.) has been send into the world of wisdom. May the exciting memories on barrel cortex and somatostatin neurons (as well as on all team members and especially her invaluable supervisor Mirko Witte) outlast all the dull cavity filling that lies ahead now!Congratulations and all the best for Tatjana!

Barrels 31 and Neuroscience 2018 was surely worth the trip
As every year, a small and a big world neuroscience conference took place right after each other. This Year Barrels 31 was held at the UC Riverside. Some 90 participants enjoyed science, lively discussions, lots of good food and the Californian sun. And not to forget Georg's talk! After re-locating to San Diego, some 28.000 neuroscientist enjoyed (despite all the bad overprized food) a conference that always is offering everything you want to hear. Georg's poster was a real success (it attracted some 80-100 people I guess) and also our Minisymposium on Cortical cell type classification was unanimously praised by the audience - and yes, it was excellent science that was delivered by the 6 speakers. Let's do it again at Uncle Sam next year in Chicago.

Petilla comes to Copenhagen
What is a cell type? How to classify them? How to name them? Can we access their function?If you are interested in these kinds of basic questions, then Copenhagen was the place to be during the last few days. Ed Lein and Rafa Yuste organized a terrific Brain Conference at the beautiful Moltke Palais, which hosted some 100 people of many different fields, all eager to work towards answering the above questions. Sparked by the fanstastic progress of single cell transcriptomics, the question that was in Petilla "Can we classify cortical neurons" has now turned into "How can we reasonably do it". The panel discussion showed the many issues still to be solved but in my opinion, this is just a matter of time.

113th meeting of the Anatomical Society in Rostock
This is Marko, not Mirko!Whereas Mirko gave an instructive presentation on transgenic animal research, Marko was one of the stars on the same day, when we had a boat trip to Guido Dehnhard's research station, close to Warnemünde. Usually Marko helps the scientists to unravel how the vibrissae help to find fish or to orient in unsteady envrionments. But this day Marko was simply spoiled with lots of fish to let some 100 anatomists pad him.
Altogether, it was an interesting and well-organized meeting and we can conclude that Anatomy is doing well in Germany and beyond.

Business trip 2018
OOPS, we did it again!Yesterday 16 people crazy for canoeing and other fun stuff drove to Northeim. First we had a very civilized trip on the Rhume (and the winner was ...;-), then we cooled us down with lot's of ice cream in the lovely timber-framed city center (and the winner was .... ;;-), followed by a minigolf competition (where of course the winner was ..... ;;;-). For all of us who did not have enough (food), the restaurant at the Burg Plesse provided us with big plates and plenty of drinks (with no competition :-(
Thanks to all organizers - and, of course, we will do it again :-)

EMBO meeting on Interneurons
Every 3 years a group of interneuron lovers meets on the beautiful island of Mallorca to communicate the progress achieved on this exciting class of neurons. Their development, their circuit features and their functions all become more and more clear. This became obvious in the keynote lecture on GABAergic projection neurons but also in lectures on transcriptomic cell types (we are at 14 types of VIP neurons!) and on neuropeptide-mediated plasticity. Georg's poster on intersectional Rabies tracing of parvalbumin neurons was well received, too.Thanks are due to Oscar Marin and the other organizers for bringing exciting science to a marvelous place.

Barrels and beyond 2018 delivers excellent science to Göttingen
On May 24th and 25th, the conference "Barrels and beyond 2018" attracted some 90 participants to the MPI for Experimental Medicine. This conference was sponsored by the CRC 889 (Cellular mechanisms of sensory processing), CNMPB and GGNB, and also followed the tradition of meetings organized by the research unit BaCoFun. All talks were simply great, with the plenary lectures really being outstanding. Vivid discussions and plenty of food (and drinks) rounded up this remarkable meeting. A big thanks to all involved helping hands! Let's hope to continue this series in 2 years in Amsterdam, Zürich or Lausanne and in 4 years again in Göttingen.

Successful thesis defense
With her excellent thesis defense and the wonderful convocation ceremony, the smoothing and polishing of another scientific gem was finally accomplished. The Spanish bull head certainly captures well some of the virtues that were necessary on the way. Thanks are due to Robin, Mirko and Kamila, as well as the many others that helped making this happening.
2018-04-03
Triple achieved!
This is no April's joke, After 2 extensive reviews on epigenetic mechanisms of neural development, Tran Tuoc and his group has just gotten provisionally accepted a manuscript in Stem Cell Reports. Here they report on BAF interaction with Wnt signaling in late embryonic development of cerebal cortex. Stay tuned for the publication list update!
2018-03-20
New Publication
The first publication in 2018 is out!Thanks to meticulous reading and writing by Godwin and Eman, scientists can now access basically everything that is known about transcriptional and epigenetic control of mammalian olfactory epithelium development.
Congratulations!

Update on Conferences
Please note that there is a final program for the Barrels and Beyond conference now available. Please checkIt has a terrific speaker list and will be certainly worth participating in. Registration deadline is 01.03.2018.
Also the EMBO workshop on Interneurons has announced its speakers list. Please check
Finally, it is worth mentioning that this years Barrels meeting (31!) will take place at UC Riverside, just preceding the SfN meeting in San Diego. There a minisymposium will be organized by Stacy Sorensen and Jochen Staiger on cortical cell type classification featuring (amongst others) Marcel Oberländer, Javier DeFelipe and Bernardo Rudy.
See you there!

Barrel Cortex Function - Special Issue in NEUROSCIENCE
Please check out this very comprehensive issue!Barrel Cortex Function Special Issue Editorial
Sensorimotor circuits allow the coordination of sensoryinformation and motor behavior and are pivotal tosurvival in challenging and dynamic environments. Toorchestrate a broad spectrum of possible outcomes,sensorimotor circuits consist of intricate networks ofmany different sensory, motor and associative(sub)cortical regions and include complicated wiringschemes and extensive flow charts. Understanding theorganizational principles of the underlying brain circuitryfrom synapses to cell types and from microcircuits tocomplex networks and behavior would be a majorachievement.The primary somatosensory (or: barrel) cortex ofrodents is widely used for studying molecular, cellularand circuit mechanisms underlying sensory-guidedbehavior. This system encodes tactile stimuli acquiredby the large facial whiskers located on the snout of theanimals. The conscious perception of tactile stimuli isalso highly relevant in the daily life of humans whenperforming fine-grained motor behavior, objectrecognition or social interactions, although we mainlyuse receptors on the finger tips. Especially for therehabilitation of stroke or amputees, the manifoldaspects of somatosensory transduction and processinghave to be better understood to translate them intobetter therapy.In 2016, the 3rd in a series of bi-annual meetings onsensory cortical circuits – with an emphasis on thebarrel cortex – was organized by Fritjof Helmchen,Jochen Staiger, Heiko Luhmann and Christiaan de Kockin Amsterdam (VU Amsterdam) and brought togetherexperts on cortical circuitry, behavior and related topics.This meeting series was prompted by a successfulinternational collaborative consortium, Research Unit1341 on Barrel Cortex Function (BA-CO-FUN), begun in2010 and supported by the German and Swiss nationalresearch science foundations (DFG-SNF). Amsterdam2016 followed meetings in 2012 (Barcelona FENSsatellite) and 2014 (Go¨ ttingen), was attended by over160 participants, and featured sessions on‘‘Development”, ‘‘Inhibition”, ‘‘Linking Circuits toBehavior” and ‘‘Active Somatosensation”. Initialdiscussions on this special issue in NEUROSCIENCEemerged during the Amsterdam 2016 meeting, fueledby inspiring presentations from both senior and juniorscientists. It was felt that the time was ripe for a widerangingreview of the field, along thematic lines similarto those represented at the meeting. Contributions tothis special issue feature several speakers from themeeting, as well as the work of experts not directlyrelated to the BA-CO-FUN meetings or consortium.In short, we bring together a series of manuscripts ontopics that continue to be at the center of interest of theconsortium and associated meetings: the first section(‘‘Barrel Cortex Function”) features work from Stu¨ ttgenand Schwarz (2018), Fox (2018), Argaman and Golomb(2018), Kwon et al. (2018), Helmchen et al. (2018), Baleand Maravall (2018), and Estebanez et al. (2018) on organizationalprinciples of (predominantly) barrel cortex. The second section (‘‘Sensory Periphery”) features manuscriptsfrom Campagner et al. (2018) and Takatoh et al.(2018) on the sensory organ of the somatosensory system:the whiskers and sensory afferents. The third section(‘‘Cortical Inhibition”) is on the structure and function ofinhibitory components of barrel circuits with contributionsfrom Hu and Vervaeke (2018), and Feldmeyer et al.(2018) The fourth section is dedicated to ‘‘Linking Circuitsto Behavior” with manuscripts from McElvain et al. (2018),Guest et al. (2018), Higashikubo and Moore (2018),Auffret et al. (2018), Sabri and Arabzadeh (2018),Schäfer and Hoebeek (2018), and Mohan et al. (2018).The special issue concludes with a section on changesobserved in sensory circuits during development or as aresult of neuronal activity (‘‘Development & Plasticity”)with contributions from Martini et al. (2018), Luhmannand Khazipov (2018), Jamann et al. (2018), and Papaleand Hooks (2018).

Christmas Celebration 2017
On an awfully rainy Wednesday the Institute went to the restaurant "Lockemann" in Herberhausen, unfortunately by car and bus, instead of hiking there. Well, the trip was worth it. Excellent German (!) cuisine and good company, together made up a very pleasant evening. One more week to go until a Merry Christmas.

Neuroscience 2017
The big meeting is over. It was a kind of trance. 30000 people, 13000 posters and innumerable lectures. The future of neuroscience happens, everyday, somewhere in world - most often in the US. HBP pushed them. They show us how to do it. BRAIN is now also B.I.C.C.C.Well, it is fun to be a German neuroscientist/neuroanatomist anyway. Especially when your (Alvar's) poster is so well received. VIP neurons in any form and at any level of detail, people like it.

Barrels 30 in Baltimore was a big success
On November 8th and 9th roughly 110 scientists and barrel afficionados met at the Johns Hopkins University in Baltimore to report on recent findings in structure and function of the whisker-to-barrel (and beyond) system. In the first session chaired by Jochen Staiger, Alvar Prönneke gave an excellent talk on his current state of understanding of VIP interneurons. Also Xiaolong Jiang, Hillel Adesnik and Bernardo Rudy had excellent contributions to this session. We also honored Tom Woolsey for the discovery of the Barrel cortex and starting (with Dan Siimons) this meeting, which goes on now since 30 years!

It is the final reward for Xiaojuan after a long struggle to comprehensively survey synapses formed by VIP-expressing GABAergic boutons through a combination of pre-embedding YFP-staining and post-embedding GABA-immunogold labeling. Much to our own surprise at most some 37% of a subcellular target structure is formed by GABAergic neurons, thus, as a population the VIP cells can not be interneuron-specific interneurons.

Business trip 2017 - reprise
It is more about the picture than anything else ... . 17 scientists from 9 different countries standing in front of the Witzenhausen green house to see coffee, cocoa, papaya, stevia, banana, and and and. Not to forget calabasses. That really worked for us.

Memorial symposium for Michael Frotscher
Some 100 friends and colleagues gathered on Friday, September, 1st, in Hamburg to hold a memorial symposium for Prof. Dr. Dr. h.c. Michael Frotscher, who suddenly died in May this year. What has been planned to be a symposium on the occasion of his 70th birthday sadly had to be renamed but nevertheless took place to show the appreciation and to express the gratitude of many former colleagues, friends and co-workers to this exceptional scientist.

Business trip 2017
No joke - our business trip this year led us to the small but very beautiful city "Witzenhausen" being located in North-Hesse. It held a lot of pleasant surprises for us. A green house of the University of Kassel with lots of exciting plants. A microbrewery with (basically) unlimited lager to test. A very relaxed Café (Ringelnatz), with a pleasant athmosphere. For the brave ones, a jump into the green lake and some home-made tarte flambée rounded up a perfect day.Thanks are due to the organizers for doing a great job!

The Anatomische Gesellschaft conference was a big success
From Tuesday 20th to Saturday 24th of September the 111th meeting of the Anatomische Gesellschaft took place at the Center of Anatomy of the UMG. With roughly 400 participants it was more than a big success, it was a record breaker. From an Institute for Neuroanatomy perspective the most exciting happenings were the Anatomy Slam at the Lumiere, where Georg Hafner was the secret winner. Well done, Georg!The preconference workshop on teaching saw Mirko Witte giving his peers an insightful time, when he used the latest tricks in didactics to teach the teachers on the subject of voluntary movements. Thanks for a great lecture, Mirko.
On Saturday, Julien Guy gave a wonderful talk to show the fascinated colleagues that the first-ever two-photon-targeted patch-clamp recordings at German anatomical institutes happened in our lab. Thanks for keeping the faith, Julien!
And last but not least, Alvar Prönneke's Cerebral Cortex paper was elected "Paper of the Year" by the members of the Anatomische Gesellschaft. Congratulations, Alvar!

Free PhD student position
Topic: Functional analysis of synaptic networks formed by cortical GABAergic interneurons
In the project we will analyze the inhibitory circuitry within the columnar structure of the somatosensory (barrel) cortex. GABA-releasing interneurons play a central role in different aspects of cortical information processing. We will use a broad spectrum of electrophysiological, histochemical and microscopic methods. The core methods are paired whole-cell patch-clamp recording, optogenetic stimulation and mapping of synaptic inputs of interneurons in acute brain slices. Afterwards the neurons will be stained and quantitatively reconstructed in 3D (see Walker et al., Nature Communications 2016; Proenneke et al., Cereb. Cortex 2015).
