Attention has been found to have a wide variety of effects on the responses of neurons in
visual cortex. We describe a model of attention that exhibits each of these different forms of …

▪ Abstract Single-unit recording studies in the macaque have carefully documented the
modulatory effects of attention on the response properties of visual cortical neurons …

The small visual area known as MT or V5 has played a major role in our understanding of
the primate cerebral cortex. This area has been historically important in the concept of …

The biased competition theory of selective attention has been an influential neural theory of
attention, motivating numerous animal and human studies of visual attention and visual …

Spatial attention is comprised of neural mechanisms that boost sensory processing at a
behaviorally relevant location while filtering out competing information. The present review …

Primates use a combination of smooth pursuit and saccadic eye movements to stabilize the
retinal image of selected objects within the high-acuity region near the fovea. Pursuit has …

The processing of visual information combines bottom-up sensory aspects with top-down
influences, most notably attentional processes. Attentional influences have now been …

Previous single-unit studies of visual cortex have reported that spatial attention modulates
responses to different orientations and directions proportionally, such that it does not change …

Primates use two types of voluntary eye movements to track objects of interest: pursuit and
saccades. Traditionally, these two eye movements have been viewed as distinct systems …

Natural visual scenes are cluttered and contain many different objects that cannot all be
processed simultaneously. Therefore, attentional mechanisms are needed to select relevant …
