Posterior parietal cortex and the filtering of distractors

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.

Neural fate of ignored stimuli: dissociable effects of perceptual and working memory load

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.

Capacity limits of information processing in the brain

Surprise-induced blindness: a stimulus-driven attentional limit to conscious perception.

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.

Attentional modulation of visual processing.

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.

Attentional Routes to Conscious Perception

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.

Causal contributions of the left frontal eye field to conscious perception.

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.

Visual attention: Insights from brain imaging

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.

Selective attention gates visual processing in the extrastriate cortex.

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.

Feature-based attention influences motion processing gain in macaque visual cortex

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.

Neural mechanisms of selective visual attention.

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.

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.

A neural basis for visual search in inferior temporal cortex

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.

Attentional requirements in a ‘preattentive’ feature search task

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.
