The 160th Brain Club welcomed Dr. Teruyoshi Nakagawa (Vanderbilt University), who was temporarily returning to Japan.。The title is "Visualizing putative ions and water molecules in the ion conduction path of the AMPA receptor"。AMPA receptors are responsible for rapid excitatory transmission in the central nervous system、Elucidation of its structure and function is an important theme that expands the possibility of clinical application as well as basic science.。Dr. Nakagawa uses cryo-EM to、2.3Ca by resolution reaching Ų⁺The structure of transmissive AMPA receptor has been clarified。Interestingly, when a highly conserved gate (SYTANLAAF) in the AMPA receptor opens upon channel opening,、Ca in the same area²⁺you have told me to join。Probably Na⁺Along with inhibiting the influx of other ions such as、efficient Ca²⁺It is considered a mechanism for achieving transparency.、We all listened with great interest.。

The 159th Brain Club was held on August 10th with Dr. Mototaka Suzuki from the University of Amsterdam。Subject: General anesthesia decouples cortical pyramidal neurons: it's an update。Face-to-face only、And I was worried that there would be few people because it was during the summer vacation.、Many people participated and had lively discussions.。(I missed the timing to take a picture, so only some people are in the picture)。

Fund for the Promotion of International Joint Research (International Leading Research) "Multidimensional Analysis of Memory Mechanisms - From nm to mesoscale/millisecond to day scale"'s first Retreat in GotembaIt was held from August 5th to 8th at。Max Planck Florida Institute of Neuroscience (USA) and Interdisciplinary Institute of Neuroscience (IINS) -BordeauxNeurocampus(France) and domestic (Kyoto University, Keio University, Tokyo University, Niigata University, NIG) gathered many PIs, postdocs and researchers.、Discussions continued late into the night。Ms. Delina, who gave an oral and poster presentation from Yuzuzaki Lab, was selected as one of the three poster award winners.。Thank you for your visit。With the support of this grant, for the next 7 years (10 years if it passes the examination)、International exchange and joint research centered on graduate students, postdocs, and young researchers are expected to progress.。

Mr. Nozawa, who received his degree (Doctor of Medicine) in March this year,、2023Received the Toshihiko Tokizane Memorial Award for Outstanding Doctoral Research in Neuroscience at the Japan Neuroscience Conference in Sendai。Nozawa also attended the degree conferment ceremony held at Keio University in March.、Selected as a representative of the Graduate School of Medicine。Congratulations!。

Interview-kun's paper "C1ql1-Bai3 signaling is necessary for climbing fiber synapse formation in mature Purkinje cells in coordination with neuronal activity” was published in Molecular Brain magazine。Cerebellar Purkinje cells form multiple climbing fibers and synapses when young、Unnecessary synapses are pruned during development, except for one climbing fiber。In this paper、climbing fiber：1 Purkinje cell：1Even in the mature cerebellum, which has established the control mode of、By increasing the expression of C1ql1 and Bai3、Purkinje cells create multiple climbing fibers and synapses again、Climbing fibers usually branch in the anterior-posterior direction,、Newly formed synapses originate from branches of climbing fibers that diverge in the medial-lateral direction、They discovered that the presence of electrical activity in climbing fibers and Purkinje cells is necessary for new synapse formation.。Even when the GluD2 glutamate receptor is knocked out after maturation,、It is known that the internal and external branches of multiple climbing fibers form synapses with Purkinje cells.、We also found that this phenomenon is also dependent on C1ql1-Bai3 signaling。

The 158th Brain Club was held on July 14th。This time, Professor Yusaku Iwasaki of Kyoto Prefectural University gave a lecture titled "Direct effects of food-related factors on vagal afferent nerves and their relationship to eating, metabolism, and mental functions."。
It was a semi-closed event that was held onsite only.、A lively discussion took place over time。

The 157th Brain Club was held on June 15th。This time, Professor Imayoshi from Kyoto University.、This is a double feature by Mr. Michikawa.。
・Dr. Itaru Imayoshi (Graduate School of Life Sciences/Institute of Medical Biology, Kyoto University) "Optogenetic analysis of transcription factor expression dynamics that determines the differentiation fate of neural stem cells"
・Dr. Takaaki Michikawa (Institute of Biomedical Sciences, Kyoto University) "Technology and prospects for observing the whole brain"
It was held on-site only.、Enthusiasm for science by both professors led to a lively discussion.。

alreadyGuidanceHowever, Yuzu Lab has been selected for the International Joint Research Acceleration Fund (International Leading Research) ``Multidimensional analysis of memory mechanism – from nm to mesoscale / millisecond to day scale''。Next 7 years (up to 10 years)、We will work on international exchange and development of young researchers, mainly postdocs and graduate students.。

postdocs and graduate students、Max Planck Florida Institute of Neuroscience (USA) and Interdisciplinary Institute of Neuroscience using this framework (IINS) -Short-term and mid-term study abroad at Bordeaux Neurocampus (France)。Interested graduate students and postdocs should visit Grant's website。the poster isInternational Leading Research Poster 230613

At the 156th BrainClub、Dr., Laboratory for Learning and Memory Neural Networks, RIKEN Center for Brain Science. Joshua P. We invited Dr. Johansen (5/10)(Wed) 16:00~17:30）。The title is "Constructing Emotional Representations in the Brain"。sensory input、physiological state of the body、and the cognitive component、Mechanisms controlling memory formation via emotion、He talked about hierarchical and distributed neural network models with recent findings.。The day was held in a hybrid format, and lively discussions took place over time.。

2022Annual (54th) Naito Memorial Prize for Science Promotionwas awarded to Yuzuzaki。3The presentation ceremony was held at the Industrial Club of Japan on the 16th of the month.。
The award-winning research theme is "Elucidation of the molecular mechanisms that control functional and structural synaptic plasticity"。Thank you to the collaborators, Yuzu Lab's colleagues and OB。
