Control of goal-directed and stimulus-driven attention in the brain

The human brain is intrinsically organized into dynamic, anticorrelated functional networks

During performance of attention-demanding cognitive tasks, certain regions of the brain routinely increase activity, whereas others routinely decrease activity. In this study, w...

Common Blood Flow Changes across Visual Tasks: II. Decreases in Cerebral Cortex

Abstract Nine previous positron emission tomography (PET) studies of human visual information processing were reanalyzed to determine the consistency across experiments of blood...

Neural Systems for Visual Orienting and Their Relationships to Spatial Working Memory

Abstract We investigated neural correlates of human visual orienting using event-related functional magnetic resonance imaging (fMRI). When subjects voluntarily directed attenti...

A PET study of visuospatial attention

Positron emission tomography (PET) was used to identify the neural systems involved in shifting spatial attention to visual stimuli in the left or right visual field along foveo...
