What is the neural code and statistical structure of neural states characterizing stress? Our new work out in Nature answers these questions and more. Thanks to my amazing co-first @_fxia, and @StefanoFusi2 and @mazen_kheirbek for invaluable guidance๐งต๐ https://t.co/cYMOsaEqaV

Excited to share our new paper out now @Nature, where we identified neural signatures of stress susceptibility and resilience in the amygdala-ventral hippocampal network to enable control of anhedonia! < https://t.co/8sd31UV0Ng> Thread below:

So happy to see this work out! We studied when brain connectomes can be used to accurately predict neural activity, and when they can't. Happy to chat more about it, please do reach out if interested. https://t.co/ZRTzBRpUV7

Thrilled to see our TinyRNN paper in @nature! We show how tiny RNNs predict choices of individual subjects accurately while staying fully interpretable. This approach can transform how we model cognitive processes in both healthy and disordered decisions.

Out today in @Nature: we show that individual neurons have diverse tuning to a decision variable computed by the entire population, revealing a unifying geometric principle for the encoding of sensory and dynamic cognitive variables. https://t.co/sqNl4v8CgR

AI can take many forms, but it's clear that the chat format is the one that has truly taken off. I think this reveals a fundamental truth about human thought: we think best in dialogue, even when our counterpart isnโt human.

Excited to share our latest preprint with @CamilloPadoaSch and @xjwanglab! We present a biologically plausible framework showing how neural circuits compute & compare value to drive flexible economic decision making.

Value-guided decisions are at the core of reinforcement learning and neuroeconomics, yet the basic computations they require remain poorly understood at the mechanistic level. For instance, how does...

New preprint with @mBeiran on a theory of multiregion recurrent neural networks! We study networks where regions have a mix of random and structured connectivity, with low-rank โcommunication subspacesโ between regions enabling selective activity routing. https://t.co/AbyrLJwedm
