Excited to share work from postdoc @thomaszluo and grad student Tim Kim! Just posted on bioRxiv. https://t.co/vvaAAIXK6m

New unsupervised method for learning latent dynamics (Kim et al., in prep) reveals that decision-making activity in frontal regions of rats is composed of two phases.

A simplified model of these two phases accounts for a variety of phenomena (including stepping vs ramping neural profiles), and precisely predicts internal decision commitment times.
