Happy to have this finally out! TL;DR: The evolution of beliefs over time can be formulated as a dynamical system, and OFC neural activity appears to implement this system with its own dynamics. These emerge without explicit supervision—when animals learn to predict value in simple Pavlovian tasks

The real American 🇺🇸 “brain drain” isn’t that a few established scholars might get new jobs outside the US, it’s the enormous number of grad students - particularly international grad students - who can’t or won’t study in the US now or in years to come. That’s the body blow.

Today I received a note from a grad student who lives in Tehran. Her note gives you firsthand experience of what it’s like to live in a city that is being bombed, and what it’s like to be young and feel despair about your future. rezashadmehr.blogspot.com/2026/03/hope...

Many neuroscientists suspect brain mechanisms for natural behaviors are ‘specialized’, whereas mechanisms for trained behaviors are ‘general’. Where does this belief come from? Do biologists believe it? Seems like a conflation of ‘natural’ with pseudoscientific notions of ‘innate/hardwired’

If neuroscience is serious about building general principles of brain function, cross-species dialogue must become a core organizing principle rather than an afterthought, writes @suthanalab.bsky.social. #neuroskyence www.thetransmitter.org/animal-model...

By the way, if you’re interested in working together on problems like this, I’m starting my lab at UCSF this summer. Get in touch if you’re interested in doing a postdoc! More info here: wj2.github.io/postdoc_ad (7/7)

Grateful to @pewtrusts.org for funding our snow fly work, in collaboration with Sebastian Brauchi at Universidad Austral de Chile. We are now looking for post-docs to work on the biophysical mechanisms that allow snow fly neurons and muscles to function below zero. newsroom.uw.edu/news-release...

I’m so excited to be a part of this! Looking forward to interesting dialogues btw researchers already working at a massive scale and those trying to grow out ‘bespoke’ systems (like myself w/ chickadee neuroscience)

My latest Aronov lab paper is now published @Nature! When a chickadee looks at a distant location, the same place cells activate as if it were actually there 👁️ The hippocampus encodes where the bird is looking, AND what it expects to see next -- enabling spatial reasoning from afar bit.ly/3HvWSum

So excited to see @hannahpayne.bsky.social‘s paper out today: rdcu.be/eqAd4 It’s a beautiful result, and using a great model species for this question makes it powerfully clear and simple. Scaling up tools in a single model system won’t get you there on its own!

Hi friends, If you haven't seen it already, I was part of a mess this week — about science in the United States, and about NIH research aimed at understanding things like Alzheimer's, schizophrenia, autism, and depression. 🧪 Thread with some details. 🧠📈 🧠🤖 1/10
