Roles for the pre-supplementary motor area and the right inferior frontal gyrus in stopping action: Electrophysiological responses and functional and structural connectivity

► We used fMRI in healthy adults and multiple methods in a single epilepsy patient. ► We studied the presupplementary motor area and right inferior frontal gyrus. ► The preSMA and rIFG are structurally and functionally connected. ► Gamma activity in preSMA occurs before rIFG in anticipation of action control. ► Beta-band coherence between preSMA and rIFG occurs during action control.
