Normal human behavior and cognition are reliant on a person’s ability to inhibit inappropriate thoughts, impulses, actions. The temporal spatial advantages of event-related functional MRI (fMRI) were exploited identify cortical regions that showed transient change in fMRI signal after the withholding prepotent motor response. specificity design also minimized possible contamination from response inhibition errors (i. e., commission errors) other extraneous processes. Regions identified strongly lateralized right hemisphere included middle inferior frontal gyri, limbic area, anterior insula, parietal lobe. Contrary prominence traditionally given ventral for inhibition, results suggest is accomplished by distributed network.
