How do oscillatory dynamics and synchrony patterns change during cognitive control of goal directed behavior? Inhibition of prepotent actions is an essential component of self-regulation of behavior. Abnormal response inhibition has been implicated as a core dysfunction in a spectrum of psychiatric disorders characterized by impulsive behaviors, such as attention deficit disorder, antisocial behaviors, and substance abuse and dependence [1], [2], [3]. Neural substrates of response inhibition have been studied in humans using Go/NoGo tasks that require a speeded motor response to the Go stimuli and withholding a pre-activated response when a NoGo stimulus is presented. Studies using event-related brain potentials (ERPs) have identified specific neuroelectric components that discriminate between Go and NoGo conditions and presumably reflect activation of distinct functional networks supporting response execution and response inhibition [4], [5], [6], [7].
