Convergence of proprioceptive and visual feedback on neurons in primary motor cortex
An important aspect of motor function is our ability to rapidly generate goal-directed
corrections for disturbances to the limb or behavioural goal. Primary motor cortex (M1) is a
key region involved in feedback processing, yet we know little about how different sources of
feedback are processed by M1. We examined feedback-related activity in M1 to compare
how different sources (visual versus proprioceptive) and types of information (limb versus
goal) are represented. We found sensory feedback had a broad influence on M1 activity …
