🧩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👇

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).

NIMH Data Archive is now also imposing NIST/ISO requirements (like NBDC). Not sure how many labs actually have the resources to meet these requirements. Is the golden era of open brain imaging data basically over?

Longer fMRI brain scans boost reliability—but only to a point
Around 30 minutes of imaging per person seems to be the “sweet spot” for linking functional connectivity differences to traits in an accurate and cost-effective way.

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).

Ongoing thoughts at rest reflect functional brain organization and behavior
Resting-state functional connectivity (rsFC)-brain connectivity observed when people rest with no external tasks-predicts individual differences in behavior. Yet, rest is not idle; it involves streams...
