How do intrinsic timescales, which reflect the temporal window of neural processing, mature during development? This study by @goliashf.bsky.social @ted-satterthwaite.bsky.social &co identifies a hierarchical trajectory, from sensorimotor to association cortices. 🧪 #NeuroSky plos.io/46RzqRG
Developmental patterns of intrinsic timescale.
(a) Average timescale increases during development in youth  (b) Age effects quantified as partial R2 are depicted across the cortex, displaying a heterogeneous spatial distribution. (c) Age effects on intrinsic timescale were compared to the S–A axis, identifying a hierarchical pattern of developmental patterns in intrinsic timescale along the S–A axis. The results demonstrate that intrinsic timescale in association regions increases during development in youth while it remains relatively stable in sensorimotor regions.

Train your model on a task, or fit it to biological data? And once it's optimized, what does it tell us about the brain? 🧠 In our #BernsteinConference satellite workshop, we'll discuss these questions through the lenses of different optimization methods. Check it out in Room 3.104! 🤓😉

I feel like over the past few months (even before the watermarking) AI models have degraded quite a lot when it comes to writing. It’s so much that I stopped using them to fix grammatical errors and all. Am I the only one? Claude specifically is the worst you can identify it in like 3 sentences.
