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.

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!

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.

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"!

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.

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.

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.

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

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.

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!

Are hippocampal Martinotti cells different? At least in the manuscript of Hurtdo-Zavala et al., entitled
TRPV1 regulates excitatory innervation of OLM neurons in the hippocampus
we helped to show Camin Dean's group that they display interesting molecular and circuit mechanisms that so far haven't been detected in the neocortex.

Christmas celebration 2016
No pictures but anyway big fun! Maybe we were just too busy with the good food at the restaurant "Abessina" or too baffled about all the more or less beautiful presents that were unveiled during our "Wichtel event". So, it was a perfect wrap-up of a nice and successful year in the lab.

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).

Student Assistant for single cell reconstruction
We offer a position as a student assistant (10h or 20 h per week) to contribute to a DFG funded research project dealing with the classification of cortical neurons (De Felipe et al., Nature Reviews Neuroscience 2013). Your obligation is to reconstruct dye-filled neurons that were electrophysiologically characterized. For this purpose we use the software “Neurolucida”. Requirements are (i) a dedication to working at a microscope, (ii) three-dimensional thinking and (iii) computer knowledge (Windows). We prefer long-term commitments due to the rather long learning period.
