Abstract:Food-handling offers unique yet largely unexplored opportunities to investigate how cortical activity relates to forelimb movements in a natural, ethologically essential, and kinematically rich form of manual dexterity. To determine these relationships, we recorded spiking activity in mouse forelimb M1 and S1 and tongue/jaw M1. Activity in all areas was strongly modulated in close association with discrete active manipulation events that occurred intermittently as mice fed. Each area's activity was also partly… Show more
