(1/n) How can we infer single-trial communication between 🧠 regions? Check out our ICML 2025 paper: “Accurate Identification of Communication Between Multiple Interacting Neural Populations,” by Belle Liu and @jsacks.bsky.social in my lab: arxiv.org/abs/2506.19094
Accurate identification of communication between multiple interacting neural populations
Neural recording technologies now enable simultaneous recording of population activity across many brain regions, motivating the development of data-driven models of communication between brain region...

Arousal as a universal embedding for spatiotemporal brain dynamics - Nature
Reframing of arousal as a latent dynamical system can reconstruct multidimensional measurements of large-scale spatiotemporal brain dynamics on the timescale of seconds in mice.

Super excited about our 2-day @cosynemeeting.bsky.social workshop on learning that pays tribute to the diversity of timescales, teaching signals and circuits that work together to shape adaptive behaviors, and where we hope to bridge insights from behavior, dynamics, and learning rules! #cosyne2025
Excited to share our #cosyne25 workshop on learning across timescales! Check out our awesome line-up of speakers across both days: learning-fast-and-slow.github.io

The International Brain Laboratory reproducibility platform paper is now published at eLife. An amazing effort by many different labs and individuals to understand and improve the reproducibility of electrophysiological measurements in mice. 🧠

I just wrote a book about how the type of work @markhisted.org is doing is key to breaking through the bottlenecks holding back new treatments for brain and mental disorders (from Alzheimers to depression). Seeing his work in danger makes me ill, and angry.

Compelling pushback from @jmgrohneuro.bsky.social and the Board of Scientific Counselors at the National Institute on Mental Health (NIMH) regarding termination of tenure-track investigators driven by DOGE.
