UC San Francisco retreat! Taking home the incentives for connecting neuroscience to the field of machine learning and AI. Intrigued by the recent leap on Alzheimer’s disease from Prof. Kampmann's talk. Looking forward to visiting the lab. Thanks Alex Buckley for helping us out. #RikenUCSF

The beautiful retreat has been completed, and we came to visit the UCSF Neuroscience Graduate Program Mission Bay campus to have lab tours. Great facilities, no barriers among labs, and most importantly great minds finding out brain mechanisms and novel ways to treat brain disorders. #RikenUCSF

I’ve made this video as an intuition pump for the density of #synapses in the #brain. This volume ~ grain of sand, has >3.2 million synapses (orange cubes). Peeling them away leaves only inputs on 2 #neurons. Zooming in, we see the synapses localized to the dendritic spines. #b3d

Very real interview by 竹内薫（サイエンス作家） with Joshua P Johansen from RIKEN Center for Brain Science about what led him to become a researcher. #scitwitter #scicomm #brainscience #scientists #lifelessons #journey itaintmagic.riken.jp/interviews/a-r…

𝗕𝗿𝗮𝗶𝗻/𝗠𝗶𝗻𝗱𝘀 𝗮𝗻𝗱 𝗕𝗲𝘆𝗼𝗻𝗱 A recent nature Focal Point offers a fascinating dive into Japan's national brain initiative. Discover the progress in understanding marmoset brains and the potential to tackle human brain disorders. #neuroscience nature.com/collections/bb…

Very excited to give a talk about my project in Optogenetics Gordon Research Conference associated GRS this weekend! I will talk and present a poster about our investigation of the functional input-output organization in the amygdala. Talk: 5.30-5.45pm (GMT+2), Sat July 20 grc.org/optogenetic-ap…

Researchers have generated a nanoscale-resolution reconstruction of a millimeter-scale fragment of human cerebral cortex, giving an unprecedented view into the structure of brain tissue at the supracellular, cellular, and subcellular levels. scim.ag/7Ke #WorldBrainDay

The great Senpai and informal career mentor of mine Kazumasa Z. Tanaka from OIST has shown his beautiful obsessions with the experience (context) vs place cell stories in the hippocampus at #OptoGRC2024!!👏 Optogenetics Gordon Research Conference

Come join us at SfN 2024 for an evening of socializing and fun w/ short talks from globally minded neuroscientists!! Speakers: Sayaka Inoue Sung Han Chair: Joshua P Johansen Guests: Kei M Igarashi / 五十嵐 啓 Mihaela Iordanova Anthony Hannan Dayu Lin and more non-X/Twitter colleagues!

Getting excited to give a talk in #MCCS24 just before SfN in Chicago next week!

Integrative investigation of salience processing in fear learning by Yusuke Kasuga in Joshua P Johansen lab at RIKEN Center for Brain Science RIKEN #MCCS24

Are you a Japanese student interested in a postdoctoral fellowship in the US? The Chan Zuckerberg Initiative has an exciting new fully-funded Global Science Scholars program to pair students who have received their undergraduate or doctoral degrees in Japan with US bioengineering

Check out a new lab paper from Mayumi Watanabe's thesis work showing how different subregions of medial prefrontal cortex differentially regulate extinction of aversive memories through projections to the locus-coeruleus-noradrenaline system: doi.org/10.1038/s41380…

I’m excited to share a new paper from the lab. The study led by Xiaowei Gu reveals how the mPFC encodes complex emotional memories, using an internal model to infer emotional associations and memories via projections to the amygdala rdcu.be/el19t nature.com/articles/s4158…

🚨New preprint alert🚨 We used closed-loop optogenetics to causally test the importance of inhibitory spike timing in network function and found that manipulating PV+ cell theta phase locking in the dentate gyrus can shift seizure susceptibility (both ways!)
