Abstract

Anterior cingulate cortex {ACC} is a part of the brain's limbic system. Classically, this region has been related to affect, on the basis of lession studies in human and in animals. In the late 1980s, neuroimaging research indicated that ACC was active in many studies of cognition. The finding from EEG studies of a focal area of negativity in scalp electrodes following an error response led to the idea that ACC might be the brain's error detection and correction device
