(edited repost) Thrilled to see our computational work on adaptive shaping of behavior (we call it outcome-based curriculum learning) in PLoS Comp Biol! @wl-tong.bsky.social, @gautamreddy.bsky.social & I formalize curricula in any RL task that can be framed as sequential simple-to-complex behavior.
Adaptive algorithms for shaping behavior

We watched mice follow scent trails drawn on an “endless” treadmill. By manipulating trail geometry/statistics, perturbing mouse nose & brain, and modeling behavior with a Bayesian framework, we show that mice use predictive (rather than reactive) strategies.

Humans and Neanderthals are virtually identical at the genetic level.

Scientists are probing the differences to understand why we are here, and they aren’t.
One gene reveals clues to why humans thrived and Neanderthals didn’t
Some mice were more adept at seeking water after the gene change, signaling a behavioral change and potential cognitive advantage.

Animals’ sniffing drives rhythmic input to the olfactory system.

How does this timing contribute to perception, especially beyond first steps of olfactory processing?

We tested this using simple closed-loop optogenetics in our new paper: www.cell.com/iscience/ful...
