Journal ArticleDOI
Neural Mechanisms of Selective Visual Attention
Robert Desimone,John S. Duncan +1 more
TL;DR: The two basic phenomena that define the problem of visual attention can be illustrated in a simple example and selectivity-the ability to filter out un wanted information is illustrated.
Journal ArticleDOI
Modulation of Oscillatory Neuronal Synchronization by Selective Visual Attention
TL;DR: Neurons activated by the attended stimulus showed increased gamma-frequency but reduced low-frequency synchronization compared with neurons at nearby V4 sites activated by distracters, suggesting localized changes in synchronization may serve to amplify behaviorally relevant signals in the cortex.
Journal ArticleDOI
Selective attention gates visual processing in the extrastriate cortex.
Jeffrey Moran,Robert Desimone +1 more
TL;DR: The filtering of irrelevant information from the receptive fields of extrastriate neurons may underlie the ability to identify and remember the properties of a particular object out of the many that may be represented on the retina.
Journal ArticleDOI
Increased Activity in Human Visual Cortex during Directed Attention in the Absence of Visual Stimulation
TL;DR: The increased activity in visual cortex in the absence of visual stimulation may reflect a top-down bias of neural signals in favor of the attended location, which derives from a fronto-parietal network.
Journal ArticleDOI
Neural mechanisms of spatial selective attention in areas V1, V2, and V4 of macaque visual cortex
TL;DR: The role of attention was examined in areas V1, V2, and V4 of macaque monkeys with the use of a behavioral paradigm in which attention was directed to one of two stimulus locations and it was found that the cell's response was strongly influenced by which of the two stimuli was attended.
