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 …

The effects of attention on neuronal responses in visual cortex have been likened to a
change in stimulus contrast. Attention and stimulus contrast both modulate the magnitude of …

Although many studies have shown that the activity of individual neurons in a variety of
visual areas is modulated by attention, a fundamental question remains unresolved: can …

When attention is directed to a location in the visual field, sensitivity to stimuli at that location
is increased. At the neuronal level, this could arise either through a multiplicative increase in …

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

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 …

In mammals, the lateral geniculate nucleus (LGN) and the superior colliculus (SC) are the
major targets of visual inputs from the retina. The LGN projects mainly to primary visual …

Attention increases the contrast gain of V4 neurons, causing them to respond to an attended
stimulus as though its contrast had increased. When multiple stimuli appear within a …

The response properties of cells in the primary visual cortex (V1) were measured while the
animals directed their attention either to the position of the neuron's receptive field (RF), to a …

Visual attention, which improves perception of attended locations or objects, has long been
known to affect many aspects of the responses of neuronal populations in visual cortex …
