Unveiling residual, spontaneous recovery from subtle hemispatial neglect three years after stroke

Frontiers in Human Neuroscience, 2015
A common and disabling consequence of stroke is the difficulty in processing contralesional space (i.e. hemispatial neglect). According to paper-and-pencil tests, neglect remits or stabilizes in severity within a few months after a brain injury.

Distinct phase-amplitude couplings distinguish cognitive processes in human attention [PDF]

, 2018
Spatial attention is the cognitive function that coordinates the selection of visual stimuli with appropriate behavioral responses. Recent studies have reported that phase-amplitude coupling (PAC) of low and high frequencies covaries with spatial ...

Spatial Neglect and Attention Networks [PDF]

Annual Review of Neuroscience, 2011
Unilateral spatial neglect is a common neurological syndrome following predominantly right hemisphere injuries and is characterized by both spatial and non-spatial deficits. Core spatial deficits involve mechanisms for saliency coding, spatial attention, and short-term memory and occur in conjunction with nonspatial deficits that involve reorienting ...

Influence of hand position on the near-effect in 3D attention [PDF]

, 2008
Voluntary reorienting of attention in real depth situations is characterized by an attentional bias to locations near the viewer once attention is deployed to a spatially cued object in depth.

How Attention Affects Spatial Resolution [PDF]

Cold Spring Harbor Symposia on Quantitative Biology, 2014
We summarize and discuss a series of psychophysical studies on the effects of spatial covert attention on spatial resolution, our ability to discriminate fine patterns. Heightened resolution is beneficial in most, but not all, visual tasks. We show how endogenous attention (voluntary, goal driven) and exogenous attention (involuntary, stimulus driven ...

Overt orienting of spatial attention and corticospinal excitability during action observation are unrelated [PDF]

, 2017
Observing moving body parts can automatically activate topographically corresponding motor representations in the primary motor cortex (M1), the so-called direct matching.

The Role of Temporal and Spatial Attention in Size Adaptation

Frontiers in Neuroscience, 2020
One of the most important tasks for the visual system is to construct an internal representation of the spatial properties of objects, including their size.

Attention modulates spatial priority maps in the human occipital, parietal and frontal cortices. [PDF]

, 2013
Computational theories propose that attention modulates the topographical landscape of spatial 'priority' maps in regions of the visual cortex so that the location of an important object is associated with higher activation levels.

Gradients of spatial attention

Acta Psychologica, 1986
Abstract A reaction time technique was used to measure the distribution of attention following a cue to attend at a particular location. Reaction time to a target light increased with the distance of the target location from the cued location. This distance effect held both for targets that were more or less foveal than the cue.
