Granule cells reorient cortical trajectories to separate contexts

Martha G. Garcia-Garcia, Michał J. Wójcik, Srijan Thota, Luke Drake, Amma Otchere, Oluwatobi Akinwale, Lizmaylin Ramos, Rui Ponte Costa, Mark J. Wagner

In mice learning two tasks, cerebellar granule cells kept the low-rank geometry of premotor cortical output within each task but rotated their population trajectories apart between tasks, while cortex generalized.
