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.

Russ Vought just sent a rescissions request to Congress, signaling he intends to illegally impound funds. The $810 million highlighted in this “request” (but this is a pretext to just illegally impound the funds) is not the exhaustive list of many billions of dollars he’s impounding this year.

Vought's goals are a) to reduce scientific funding generally, and b) especially to universities. Political appointees within agencies can already block spending. This would centralize this power in the White House. By requiring unanimity, it would ensure far less money will be spent on science.
The proposed board would include Bhattacharya and Vought and would be required to reach unanimous decisions on grant awards, the officials said.

The arrangement would give Vought, the director of the White House Office of Management and Budget, a direct role in determining how the nation’s largest biomedical research agency distributes its $48 billion in congressionally-appropriated money.
