🧩New study: "Network Constraints on 𝘪𝘯 𝘷𝘪𝘷𝘰 Synaptic Alterations in Schizophrenia"

medrxiv.org/content/10.1...

We map a prominent brain-wide pattern of synaptic defects in people with Schizophrenia using PET, then model the molecular, cellular & connectomic features shaping this pattern 🧵1/3👇

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

With amazing collaborators @tfblanken.bsky.social, Han van der Maas, & Denny Borsboom 🥳
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.

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. 👇🏼

🚨 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!

Adaptive learning is coordinated across behaviour, time and neurobiology (from synapses and dendrites, to astrocytes and the systems level).

Resting-state fMRI data predicts what people are thinking and how they're thinking it ⬇️

New preprint! 🧠

Our mind wanders at rest. By periodically probing ongoing thoughts during resting-state fMRI, we show these thoughts are reflected in brain network dynamics and contribute to pervasive links between functional brain architecture and everyday behavior (1/10).
