We investigated the sensitivity of brain areas to the presence of filtering operations during overt visual search in crowded displays. Task conditions involved either visual search or predetermined simple eye movements for the detection of target digits. Furthermore, visual displays either contained letter foils that required filtering or contained only target digits. Brain imaging using positron emission tomography showed extensive overlap between areas involved in overt visual search and eye… Expand
Brain Activations during Visual Search: Contributions of Search Efficiency versus Feature Binding
TLDR
The results confirm the important role of the parietal cortex in visual search, but suggest that feature binding is not a requirement to engage its contribution. Expand
Visual search and memory search engage extensive overlapping cerebral cortices: an fMRI study
TLDR
It is proposed that the right DLPFC is associated with the process of monitoring and manipulating multiple elements, while the left FEF is involved in cognitive planning, and the right precuneus and cuneus as well as the left cerebellum are responsible for both spatial and nonspatial shifts of attention. Expand
Exploring the visual world: The neural substrate of spatial orienting
TLDR
Functional magnetic resonance imaging data suggest that the inferior parietal lobule and temporo-parietal junction are part of the network involved in human spatial orienting and exploration. Expand
Impaired attentional selection following lesions to human pulvinar: Evidence for homology between human and monkey
TLDR
Patients' contralesional contrast thresholds for discriminating the orientation of grating stimuli were elevated only when the task required selection of a visual target in the face of competition from a salient distracter, providing the first evidence that the human pulvinar plays a necessary role in modulating physical saliency in attentional selection. Expand
Temporal characteristics of neural activity related to target detection during visual search
TLDR
The results demonstrate that neural activities of multiple regions had different temporal characteristics, and the later activity around the CaS was related to the target segregation from its surroundings during the orientation contrast search. Expand
The role of the right superior temporal gyrus in visual search—Insights from intraoperative electrical stimulation
TLDR
It is found that inactivation of the middle portion of the superior temporal gyrus (STG) leads to disturbed serial exploratory visual search and the traditional view that only the right posterior parietal cortex is involved in the mediation of visual search processes is challenged. Expand

TLDR
Agreement suggests that a fixed-parameter model using spatiochromatic filters and a simulated retina, when driven by the correct visual routines, can be a good general-purpose predictor of human target acquisition behavior. Expand
Theory of visual attention thalamic model for visual short-term memory capacity and top-down control: Evidence from a thalamo-cortical structural connectivity analysis
In the theory of visual attention (TVA), it is suggested that objects in a visual scene compete for representation in a visual short-term memory (vSTM) store. The race towards the store is assumed toExpand
The Role of Temporo-parietal Cortex in Subcortical Visual Extinction
TLDR
The results support the idea that a normally functioning TPJ area plays a decisive role for the attentional network involved in detecting of visual stimuli under conditions of competition. Expand
TMS in the parietal cortex: Updating representations for attention and action
TLDR
The high temporal resolution of TMS has proved to be a particular strength of the technique and the experiments have led to hypotheses about when circumscribed regions of parietal cortex are critical for specific attentional and sensorimotor processes. Expand

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.

Superior Parietal Cortex Activation During Spatial Attention Shifts and Visual Feature Conjunction
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 aExpand
Covert Visual Spatial Orienting and Saccades: Overlapping Neural Systems
TLDR
FMRI showed that common parietal and frontal regions are more activated during the covert task than the overt oculomotor condition and the possible nature of the relationship between these two operations is discussed. Expand
Involvement of striate and extrastriate visual cortical areas in spatial attention
TLDR
Event-related potentials (ERPs) and modeling of their neural sources indicated that the initial sensory input to striate cortex at 50–55 milliseconds after the stimulus was not modulated by attention, whereas the earliest facilitation of attended signals was observed in extrastriate visual areas. Expand
Increased Activity in Human Visual Cortex during Directed Attention in the Absence of Visual Stimulation
TLDR
The increased activity in visual cortex in the absence of visual stimulation may reflect a top-down bias of neural signals in favor of the attended location, which derives from a fronto-parietal network. Expand
A Common Network of Functional Areas for Attention and Eye Movements
TLDR
Overlapping regional networks in parietal, frontal, and temporal lobes were active in both tasks, consistent with the hypothesis that attentional and oculomotor processes are tightly integrated at the neural level. Expand
A PET study of visuospatial attention
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. Expand
Functional localization of the system for visuospatial attention using positron emission tomography.
TLDR
The two attention tasks evoked largely overlapping patterns of neural activation, supporting the existence of a general neural system for visuospatial attention with regional functional specialization. Expand
The Retinotopy of Visual Spatial Attention
We used high-field (3T) functional magnetic resonance imaging (fMRI) to label cortical activity due to visual spatial attention, relative to flattened cortical maps of the retinotopy and visual areasExpand
Spatial Selective Attention Affects Early Extrastriate But Not Striate Components of the Visual Evoked Potential
TLDR
The hypothesis that spatial attention does not affect the initial activity evoked in area V1 but rather produces an enhancement within extrastriate visual areas of sensory signals arising from stimuli at attended locations is supported. Expand
