Moving attention through visual space.

On the Construction and Maintenance of Expectancies

Reaction time techniques were used to examine the role of attention in the construction and maintenance of expectancies. In Experiment I, a primed letter matching task, expectan...

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

A default mode of brain function

A baseline or control state is fundamental to the understanding of most complex systems. Defining a baseline state in the human brain, arguably our most complex system, poses a ...

Medial prefrontal cortex and self-referential mental activity: Relation to a default mode of brain function

Medial prefrontal cortex (MPFC) is among those brain regions having the highest baseline metabolic activity at rest and one that exhibits decreases from this baseline across a 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...
