A Combined fMRI and Eye Tracking Study of Human Overt Attention

Abstract

Visual attention can be voluntarily directed towards an item based on our current behavioral goals and knowledge or it can be reflexively drawn to salient features of a visual scene. Recent functional magnetic resonance imaging (fMRI) studies have proposed two partially segregated networks for these complementary top-down and bottom-up attentional control mechanisms: The dorsal frontoparietal system, which is involved in top-down attentional allocation, and a stimulus-driven ventral frontoparietal system.
