Dissociable Roles of Primary Motor and Supplementary Motor Cortex in Shaping the Neural Drive to Muscle

2025-10-30

Abstract excerpt

The primary motor cortex (M1) and supplementary motor area (SMA) are critical for motor execution and planning, yet their distinct causal contributions to modulating the neural drive to muscles remain incompletely understood. To dissociate their roles, we applied inhibitory transcranial magnetic stimulation (TMS) over M1, SMA, or a sham condition in 72 healthy participants and characterized the activity of single...
