Time Course of Executive Processes: Data from the Event-Related Optical Signal

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

This chapter discusses a series of experiments in which a pre-cue signals which of several dimensions of an upcoming stimulus is relevant on a particular trial. The event-related optical signal is used to follow the time course of activity in different cortical areas after the pre-cue. The data show two types of preparatory brain activities: (1) a domain-general set, involving first the left middle frontal gyrus and then the lateral parietal cortex; and (2) a domain-specific set, involving secondary sensory and motor areas of the brain. These data suggest that task preparation involves the operation of a hierarchical, top-down system.
