Path Asymmetry in Complex Dynamic Systems of Psychopathology This article illustrates the assumption of path symmetry in current theories of psychopathology and calls for the development of dynamical systems of mental illness that incorporate asymmetry.

Thrilled to share a new paper in @jamapsychiatry.com on path asymmetry in complex dynamic systems of psychopathology! jamanetwork.com/journals/jam...

Unattended working memory items are coded by persistent activity in human medial temporal lobe neurons - Nature Human Behaviour Paluch et al. show that unattended working memory items, as well as attended ones, are encoded in persistent activity in the medial temporal lobe.

Why I left academia and neuroscience Don't worry, this isn't yet another story of rage-quitting.

When @laurapritschet.bsky.social & Pavel Shapturenka set out to build the 28&Me + 28&He datasets, I don't think any of us could've predicted the spectacularly creative ways the datasets would be used years later. That's the power of open science. 👇🏼

The effect of spherical projections on spin tests for brain maps | doi.org/10.1162/IMAG...

Spin tests are the de facto null model for map-to-map comparisons in brain imaging. Why don't they perfectly control false positives? @vincebaz.bsky.social explores ⤵️

🚨 Excited to share the latest preprint form the lab ➡️https://tinyurl.com/32d3be9f

Here we tackle a long-standing chicken-or-egg 🐣🥚question in #autism and developmental neuroscience

➡️ Is excitation–inhibition (E:I) imbalance a "cause" or a "consequence" of #autism?

Check out what we found!
