1/7 Our paper on individual variability in decision-making is finally out in @nature.com! Inspired by the classic work by Mante and Sussillo, we trained many rats to solve context-dependent decision-making, and we found that different brains use different neural mechanisms to solve the same task!

Some glimmers of hope (but mostly confusion) this morning.

I have heard that no intramural tenure track investigators were supposed to be on the termination list although some folks clearly got termination notices.

I am actively checking into this every way I can.

This is atrocious!
The damage today (actually yesterday) to the intramural program appears to especially bad.

It also appears (although I need more confirmation) that most or all of the tenure track investigators in their first 2 years in several, and perhaps all, institutes were terminated.

Very interesting paper on a potential role for proprioceptors in sensing muscle acidosis and driving the perception of soreness.

"Sng" is a Taiwanese word for both sour taste and muscle soreness. It also imitates the natural vocalization of humans feeling sore.

Really elegant work by @behrenstimb.bsky.social group. The idea of structured memory buffers provides a nice framework to understand 'goal-progress cells’ activity in the mPFC while mice learn a common task structure across many tasks. Not the easiest paper to read but really worthwhile!
