WE often search for a face in a crowd or for a particular object in a cluttered environment. In
this type of visual search, memory interacts with attention: the mediating neural mechanisms …

neurons in inferior temporal cortex during memory-guided visual search. J. Neurophysiol. 80: …

Efficient goal-directed behavior in a crowded world is crucially mediated by visual selective
attention (VSA), which regulates deployment of cognitive resources toward selected, …

Visual selective attention is the brain function that modulates ongoing processing of retinal
input in order for selected representations to gain privileged access to perceptual awareness …

Outcomes of actions, in the form of rewards and punishments, are known to shape behavior.
For example, an action followed by reward will be more readily elicited on subsequent …

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

Luck, Steven J., Leonardo Chelazzi, Steven A. Hillyard, and Robert Desimone. Neural
mechanisms of spatial selective attention in areas V1, V2, and V4 of macaque visual cortex. J. …

It is well established that attention modulates visual processing in extrastriate cortex.
However, the underlying neural mechanisms are unknown. A consistent observation is that …

Reward-related mesolimbic dopamine steers animal behavior, creating automatic approach
toward reward-associated objects and avoidance of objects unlikely to be beneficial. …

In a typical scene with many different objects, attentional mechanisms are needed to select
relevant objects for visual processing and control over behavior. To test the role of area V4 in …
