The contribution of the right inferior frontal cortex to response inhibition has been demonstrated by previous studies of neuropsychology, electrophysiology, and neuroimaging. The inferior frontal cortex is also known to be activated during processing of infrequent stimuli such as stimulus-driven attention. Response inhibition has most often been(More)
Flexible adaptation to changing environments requires shifting of a cognitive set, one basic function of the prefrontal cortex. Set shifting, as instantiated in the Wisconsin Card Sorting Task (WCST) administered in a neuropsychological testing room, is typically achieved when subjects have no prior experiences of updating one WCST behavior to another.

One of the most prevailing views on the functional localization of human cognition is the hemispheric specialization, wherein the left and right hemispheres are implicated primarily in verbal and nonverbal functions, respectively. Cognitive control is known to involve the lateral prefrontal cortex. However, it remains unclear whether the hemispheric(More)
