The posterior parietal cortex and the prefrontal cortex are associated with eye movements
and visual attention, but their specific contributions are poorly understood. We compared the …

In the visual world, stimuli compete with each other for allocation of the brain's limited
processing resources. Computational models routinely invoke wide-ranging mutually …

Neural activity in the lateral intraparietal area (LIP) has been associated with attention to a
location in visual space, and with the intention to make saccadic eye movement. In this study …

We examined the activity of neurons in the lateral intraparietal area (LIP) during a task in
which we measured attention in the monkey, using an advantage in contrast sensitivity as …

Avoiding distraction by conspicuous but irrelevant stimuli is critical to accomplishing daily
tasks. Regions of prefrontal cortex control attention by enhancing the representation of task …

The prefrontal cortex is thought to modulate sensory signals in posterior cortices during top-
down attention,, but little is known about the underlying neural circuitry. Experimental and …

The close relationship between saccadic eye movements and vision complicates the
identification of neural responses associated with each function. Visual and saccade-related …

The analysis of a peripheral visual location can be improved in two ways: either by orienting
one's gaze (usually by making a foveating saccade) or by'covertly'shifting one's attention to …

We investigated the contribution of the lateral intraparietal area (LIP) to the selection of
saccadic eye movement targets and to saccade execution using muscimol-induced …

The faculty of attention endows us with the capacity to process important sensory information
selectively while disregarding information that is potentially distracting. Much of our …
