The limited capacity of neural processing restricts the number of objects and locations that can be attended to. Selected events are readily enhanced: the bright side of attention. However, such focal processing comes at a cost, namely, functional blindness for unattended events: the dark side of visual attention. Recent work has advanced our understanding of the neural mechanisms that facilitate visual processing, as well as the neural correlates of unattended, unconscious visual events. Also… Expand
The Neural Basis of the Attentional Blink
ABSTRACT A fundamental characteristic of visual attention is its severely limited processing capacity: We have great difficulty in attending to more than one visual event at a time. This limitationExpand
The Neural Fate of Consciously Perceived and Missed Events in the Attentional Blink
TLDR
The results suggest that medial temporal cortex permits rapid categorization of the visual input, while the frontal cortex is part of a capacity-limited attentional bottleneck to conscious report. Expand
Multiple Spotlights of Attentional Selection in Human Visual Cortex
TLDR
Functional MR imaging of human subjects as they performed a task that required simultaneous attention to two briefly displayed and masked targets at locations separated by distractor stimuli reveals retinotopically specific enhanced activation in striate and extrastriate visual cortical representations of the two attended stimuli and no enhancement at the intervening representation of distracting stimuli. Expand
Posterior parietal cortex and the filtering of distractors
TLDR
Testing the ability of a patient with bilateral parietal lesions to discriminate the features of a target surrounded by distractors of variable contrast found a finding consistent with the projections of parietal cortex to visual processing areas covering a wide range of receptive field sizes and eccentricities. Expand
Neural fate of ignored stimuli: dissociable effects of perceptual and working memory load
TLDR
Functional magnetic resonance imaging (fMRI) is used to demonstrate that the type of task that a human subject engages in determines the way in which ignored visual background stimuli are processed in parahippocampal cortex. Expand
Capacity limits of information processing in the brain
TLDR
A review of the neurobiological literature suggests that the capacity limit of VSTM storage is primarily localized to the posterior parietal and occipital cortex, whereas the AB and PRP are associated with partly overlapping fronto-parietal networks. Expand
Surprise-induced blindness: a stimulus-driven attentional limit to conscious perception.
TLDR
It is concluded that the capture of stimulus-driven attention alone can limit explicit perception, and this powerful but short-lived deficit contrasts with a milder but more enduring form of attentional capture that accompanies singleton presentations in rapid serial visual presentations. Expand
Attentional modulation of visual processing.
TLDR
Microstimulation of the frontal eye fields, one of several areas that control the allocation of spatial attention, induces spatially local increases in sensitivity both at the behavioral level and among neurons in area V4, where endogenously generated attention increases contrast sensitivity. Expand
Attentional Routes to Conscious Perception
TLDR
Evidence is shown that distinct sorts of spatial attention can have different effects on visual conscious perception, and Fronto-parietal networks important for spatial attention constitute plausible neural substrates for the interactions between exogenous spatial attention and conscious perception. Expand
Causal contributions of the left frontal eye field to conscious perception.
TLDR
The high temporal resolution and causal power of event-related transcranial magnetic stimulation is used to explore the causal contributions of the left FEF on conscious perception and to assess whether or not these effects are mediated by the orienting of spatial attention. Expand

Neural Correlates of the Attentional Blink
TLDR
It is demonstrated that an AB can be elicited by both temporal and spatial distractor interference on an attended target and that both of these interference mechanisms activate the same neural circuit. Expand
The cognitive neuroscience of visual attention
TLDR
In current conceptualizations of visual attention, selection takes place through integrated competition between recurrently connected visual processing networks, and the activation of striate and extrastriate brain regions during conditions of competition is revealed. Expand
Visual attention: Insights from brain imaging
TLDR
It is shown that functional neuroimaging is revealing much more than where attention happens in the brain; it is beginning to answer some of the oldest and deepest questions about what visual attention is and how it works. Expand
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. Expand
Feature-based attention influences motion processing gain in macaque visual cortex
TLDR
Non-spatial, feature-based attentional modulation of visual motion processing is demonstrated, and it is shown that attention increases the gain of direction-selective neurons in visual cortical area MT without narrowing the direction-tuning curves. Expand
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. 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

TLDR
This study found that it could improve the monkey's performance with microstimulation when, but only when, the object to be attended was positioned in the space represented by the cortical stimulation site. Expand
A neural basis for visual search in inferior temporal cortex
TLDR
The results suggest that inferior temporal cortex is involved in selecting the objects to which the authors attend and foveate, and this area is known to be important for high-level visual processing. Expand
Attentional requirements in a ‘preattentive’ feature search task
TLDR
It is shown that detection of differences in a simple feature such as orientation is severely impaired by additionally imposing an attentionally demanding rapid serial visual presentation task involving letter identification, demonstrating that attention can be critical even for the detection of so-called ‘preattentive’ features.
