My co-authors have yet to move to Bluesky, so I'm pleased to announce our latest work has just been published in @nature.com Neuroscience. Amazing work led by Junheng Li, revealing that falling asleep follows a predictable bifurcation pattern #neuroskyence #sleep

Falling asleep follows a predictable bifurcation dynamic - Nature Neuroscience
Li et al. propose a conceptual framework to study the phenomenon of falling asleep based on electroencephalogram data. They show that a tipping point marks the brain’s nonlinear wake-to-sleep transiti...

Tomorrow, Sept 19 | 3:30 PM, at #CCNP2025 (ccnp.ca) in Montreal, I’ll be co-chairing the symposium “Psychedelics & Psychiatry” 🍄🧠 with @swubat.bsky.social.
We’ll explore how psychedelics reshape brain circuits & behavior, bridging preclinical & clinical perspectives.

Had a fantastic time at the Neurobiology of Psychedelics GRC. Only a week yet feels like it could have been months. New community, new lab, novel and diverse ideas and perspectives, unpublished brand new research, a lot of growth. Easily one of my favourites #GRCPsychedelics

Excited to attend Neurobiology of Psychedelics GRC this week! Looking forward to deep dives into the mechanism of action of psychedelics and how they modulate neuroplasticity, cognitive flexibility, and adaptive decision-making—across behavior and neural dynamics. 🧠🍄

New preprint! 🧠🤖
How do we build neural decoders that are:
⚡️ fast enough for real-time use
🎯 accurate across diverse tasks
🌍 generalizable to new sessions, subjects, and even species?
We present POSSM, a hybrid SSM architecture that optimizes for all three of these axes!
