We are very excited to share our work using #zebrafish to study fast acting antidepressants work! Tl;dr –ketamine and related drugs drive minutes-long calcium elevations in astroglia sufficient to mediate their effects. biorxiv.org/content/10.110… Details below:

New results! Stability from subspace rotations and traveling waves doi.org/10.1101/2024.0… #neuroscience Cortical activity spirals like eddies. This may stabilize the brain and keep neural computation on track. Work by Tamal_Batabyal Scott Brincat MIT Picower Institute MIT Brain and Cognitive Sciences

How can we tell if two dynamical systems are computing the same way? Come to Mitchell Ostrow 's spotlight CosyneMeeting talk at session 5 today to learn about Dynamical Similarity Analysis! Joint work w/ Adam Eisen, me, and FieteGroup .

Thanks for the invite and the kind words Haitham Bou Ammar, I had a great time chatting with you all! 😃

Out now in Nature Neuroscience: "Centripetal integration of past events in hippocampal astrocytes regulated by locus coeruleus", nature.com/articles/s4159… With a great team: Fritjof Helmchen Johannes Bohacek Sian Duss chris lewis 👋 and (twitterless) Denise Becker. 1/5

How can we understand the way sequence models choose to combine info in their context to make good predictions? In our new ICML Conference workshop paper, Adam Eisen , FieteGroup and I provide a new theoretical lens from dynamical systems: delay embeddings arxiv.org/abs/2406.11993

Aran is a brilliant, thoughtful scientist, and a real bona-fide mensch. Students: don't miss a chance to join this lab!

Brown Engineering welcomes Peipei Zhou, Mehdi Saligane, Joy Zeng, Leo Kozachkov, and Indie Garwood to the faculty! engineering.brown.edu/news/2024-07-1…

I'm really happy to share that our paper about the astrocytic contribution to reversal learning is finally out! In this thread, I will quickly go through the main results. #Neuroscience #Research 1/10

New paper! Propofol anesthesia causes unconsciousness by making your brain more chaotic. It does this *increasing* inhibition, weirdly enough. Work led by Adam Eisen and Leo Kozachkov A collaboration between labs in MIT Picower Institute McGovern Institute doi.org/10.1016/j.neur… #neuroscience

"The brain has to operate on a knife's edge between excitability and chaos". He's right, you know. news.mit.edu/2024/study-rev…

Our paper is out today in Neuron! Huge thanks to my co-first author Leo Kozachkov, co-advisors Earl K. Miller and FieteGroup, and all of our co-authors - very grateful to have worked with everyone on this project!
