Neural mechanisms of selective visual attention.
TLDR
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.
Modulation of Oscillatory Neuronal Synchronization by Selective Visual Attention
TLDR
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.
Competitive Mechanisms Subserve Attention in Macaque Areas V2 and V4
TLDR
A quantitative neural model of attention is proposed to account for these findings, which are consistent with the idea that attention biases competitive interactions among neurons, causing them to respond primarily to the attended stimulus.
Neural mechanisms of spatial selective attention in areas V1, V2, and V4 of macaque visual cortex.
TLDR
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.
Increased Activity in Human Visual Cortex during Directed Attention in the Absence of Visual Stimulation
Selective attention gates visual processing in the extrastriate cortex.
TLDR
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.
Neural Mechanisms of Visual Working Memory in Prefrontal Cortex of the Macaque
TLDR
It is suggested that PF cortex plays a primary role in working memory tasks and may be a source of feedback inputs to IT cortex, biasing activity in favor of behaviorally relevant stimuli.

TLDR
Three commonly observed neuronal effects in memory-demanding tasks are repetition suppression, enhancement, and delay activity, which appear to be an intrinsic property of visual cortical areas such as inferior temporal cortex and is thought to be important for perceptual learning and priming.
High-Frequency, Long-Range Coupling Between Prefrontal and Visual Cortex During Attention
TLDR
It is found that attention to a stimulus in their joint receptive field leads to enhanced oscillatory coupling between the two areas, particularly at gamma frequencies, which may optimize the postsynaptic impact of spikes from one area upon the other, improving cross-area communication with attention.
Multiple visual areas in the caudal superior temporal sulcus of the macaque
TLDR
Several visual areas were distinguished within the caudal STS, based on differences in their visuotopic organization, neuronal properties, receptive field size, myeloarchitecture, and pattern of connections with MT.
