Prefrontal control over motor cortex cycles at beta frequency during movement inhibition.

ABSTRACT: A fully adapted behavior requires maximum efficiency to inhibit processes in the motor domain. Although a number of cortical and subcortical brain regions have been implicated, converging evidence suggests that activation of right inferior frontal gyrus (r-IFG) and right presupplementary motor area (r-preSMA) is crucial for successful response inhibition. However, it is still unknown how these prefrontal areas convey the necessary signal to the primary motor cortex (M1), the cortical site where the final motor plan eventually has to be inhibited or executed. On the basis of the widely accepted view that brain oscillations are fundamental for communication between neuronal network elements, one would predict that the transmission of these inhibitory signals within the prefrontal-central net
