Positron emission tomography was used to measure changes in the regional cerebral blood flow of normal people while they searched visual displays for targets defined by color, by motion, or by a conjunction of color and motion. A region in the superior parietal cortex was activated only during the conjunction task, at a location that had previously been shown to be engaged by successive shifts of spatial attention. Correspondingly, the time needed to detect a conjunction target increased with…

TLDR
The fronto-parietal network may be the source of spatial attentional modulations in the ventral visual system during object recognition or discrimination, and suggests that shifts of attention to visual locations of objects recruit areas involved in oculomotor programming and execution.
Posterior Parietal Mechanisms of Visual Attention
TLDR
Posterior parietal neuronal activity appears to provide critical information for shifting attention between stimuli and spatial locations, and is modulated by whether they are attended or not based on prior information.

Parietal activation during visual search in the absence of multiple distractors
TLDR
A subset of parietal regions participates in the control of visual search even in the absence of distractors, according to fMRI results.
Involvement of the human frontal eye field and multiple parietal areas in covert visual selection during conjunction search
TLDR
FMRI results suggest an involvement of the human frontal eye field in covert visual selection of potential targets during search and provide evidence for a subdivision of posterior parietal cortex in multiple areas participating in covertVisual selection, with a major contribution of the posterior intraparietal sulcus.

Functional anatomical and single-unit recording studies indicate that a set of neural signals in parietal and frontal cortex mediates the covert allocation of attention to visual locations, as

The role of the parietal cortex in visual feature binding
TLDR
Using functional MRI (fMRI), it is shown that regions of the parietal cortex involved in spatial attention are more engaged in feature conjunction tasks than in single feature tasks when multiple objects are shown simultaneously at different locations but not when they are shown sequentially at the same location.

TLDR
PET findings indicate that parietal and frontal regions control different aspects of spatial selection, and the functional asymmetry in superior parietal cortex may be relevant for the pathophysiology of unilateral neglect.
Combined spatial and temporal imaging of brain activity during visual selective attention in humans
TLDR
Together neuroimaging and e.r.p. recording showed that visual inputs from attended locations receive enhanced processing in the extrastriate cortex (fusiform gyrus) at 80–130 ms after stimulus onset, which reinforces early selection models of attention.

TLDR
It is suggested that the role of area 7 in visual attention may be mediated by the enhancement of visual responses to selected stimuli, which resembles the psychological phenomenon of selective spatial attention.

TLDR
A network approach to the localization of complex functions offers an alternative to more extreme approaches, some of which stress an exclusive concentration of function within individual centers in the brain and others which advocate a more uniform (equipotential or holistic) distribution.
Effects of parietal injury on covert orienting of attention
TLDR
The results show that damage to the parietal lobe produces a deficit in the disengage operation when the target is contralateral to the lesion, and suggest one mechanism of the effects of parietal lesions reported in clinical neurology.
Functional anatomical studies of explicit and implicit memory retrieval tasks
TLDR
These experiments suggest that areas of frontal cortex play a role in explicit recall and that an effect of priming may be to require less activation of perceptual regions for the processing of recently presented information.

TLDR
A unified theory of visual recognition and attentional selection is developed by integrating the biased-choice model for single-stimulus recognition with a choice model for selection from multielement displays in a race model framework.
