Spectral envelopes of facial movements predict intention, cortical representations, and neural prosthetic control

The paper introduces face-rhythm, an unsupervised pipeline for analyzing rodent facial movements, and shows it can decode task variables and cortical activity.

Distinct temporal difference error signals in dopamine axons in three regions of the striatum in a decision-making task

The paper shows dopamine axon activity in three striatal regions is similar but differs in reward response bias, which relates to habit and skill.
