Recent studies show that in addition to enhancing neural processing for attentionally relevant stimuli, selective attention also operates by suppressing the processing of distracter stimuli. When subjects are pre-cued to selectively deploy attention during voluntary (endogenous) attentional tasks, these mechanisms can be set up in advance of actual stimulus processing. That is, the brain can be placed in a biased attentional state. Two recent cueing studies have provided evidence for the… Expand
Anticipatory Attentional Suppression of Visual Features Indexed by Oscillatory Alpha-Band Power Increases:A High-Density Electrical Mapping Study
TLDR
Alpha-suppression mechanisms appear to operate during feature-based selection in much the same manner as has been shown for space-based attention. Expand
Oscillatory Alpha-Band Mechanisms and the Deployment of Spatial Attention to Anticipated Auditory and Visual Target Locations: Supramodal or Sensory-Specific Control Mechanisms?
TLDR
It is suggested that parietally generated alpha-band mechanisms are central to attentional deployments across modalities but that they are invoked in a sensory-specific manner during deployment of spatial attention. Expand
Oscillatory alpha-band suppression mechanisms during the rapid attentional shifts required to perform an anti-saccade task
TLDR
Low-density electroencephalography in conjunction with infra-red eye-tracking was recorded while participants engaged in both pro- and anti-saccade task blocks, implicate oscillatory alpha-band activity as a common mechanism across both overt and covert attentional deployments. Expand
Biasing the brain’s attentional set: I. Cue driven deployments of intersensory selective attention
TLDR
Brain activity associated with directing attention to one of two possible sensory modalities was examined using high-density mapping of human event-related potentials to support extensive interactions between sensory, parietal and frontal regions during processing of cue information, deployment of attention, and maintenance of the focus of attention in anticipation of impending attentionally relevant input. Expand
Mechanisms of selective inhibition in visual spatial attention are indexed by α‐band EEG synchronization
TLDR
During voluntary orienting of attention, α‐synchronization is found to dominate over desynchronization, to be topographically specific for each of eight attention positions, and to occur over areas processing unattended space in a retinotopically organized pattern, which indicates that α‐ synchronized activity is an important component of selective attention, serving active suppression of unattended positions during visual spatial orienting. Expand
Increases in alpha oscillatory power reflect an active retinotopic mechanism for distracter suppression during sustained visuospatial attention.
TLDR
Bilateral flickering stimuli were presented simultaneously and continuously over entire trial blocks, such that externally evoked alpha desynchronization is equated in precue baseline and postcue intervals and suggests that alpha synchronization reflects an active attentional suppression mechanism, rather than a passive one reflecting "idling" circuits. Expand
Expect to neglect: Cross-modal resource allocation in anticipation of visual load
TLDR
This EEG study investigated how expectancy about visual load modulated neural activity, prior to the onset of visual stimuli, and observed a sustained posterior positivity in the ERPs after high perceptual load cues, suggestive of resource allocation for the upcoming visual targets. Expand
Top-down Modulation of Neural Activity in Anticipatory Visual Attention: Control Mechanisms Revealed by Simultaneous EEG-fMRI.
TLDR
The results show that IPS and frontal executive areas are the main sources of biasing influences on task-relevant visual cortex, whereas task-irrelevant default mode network and sensorimotor cortex are inhibited during visual attention. Expand
Supramodal selective attention differentially adjusts frequency and phase of entrained oscillations in primary sensory areas and the dorsal attention network
TLDR
A differential effect of attentional focus on entrained oscillations in primary sensory areas and core areas of the dorsal attention network is shown, which suggests that these areas prioritize the attended modality by optimally exploiting the temporal structure of stimulation. Expand
Alpha Oscillations in the Human Brain Implement Distractor Suppression Independent of Target Selection
TLDR
Electroencephalography recordings are used to test the preregistered hypothesis that alpha power directly relates to distractor suppression and thus operates independently from target selection, and demonstrate that the neurobiological foundation of attention implies a selection-independent alpha oscillatory mechanism to suppress distraction.

Responses of neurons in inferior temporal cortex during memory-guided visual search.
TLDR
The results support a "biased competition" model of attention, according to which objects in the visual field compete for representation in the cortex, and this competition is biased in favor of the behaviorally relevant object by virtue of "top-down" feedback from structures involved in working memory. Expand
Competitive Mechanisms Subserve Attention in Macaque Areas V2 and V4
TLDR
A quantitative neural model of attention is proposed to account for these findings, which are consistent with the idea that attention biases competitive interactions among neurons, causing them to respond primarily to the attended stimulus. Expand
Shifting visual attention in space: an electrophysiological analysis using high spatial resolution mapping
TLDR
The data support the current view that voluntarily orienting visual attention in space leads to top-down modulations in cortical excitability of ventral extrastriate regions initiated by posterior-parietal and mediated by lateral-prefrontal cortical structures. Expand
The dynamics of shifting visuospatial attention revealed by event-related potentials
TLDR
The design enabled us to record the brain activity engaged during spatial shifts of covert attention that was independent from the physical characteristics of the cueing stimulus using event-related potentials (ERPs), and the results extend the understanding of the neural system that orients spatial attention. Expand
Attention-dependent suppression of metabolic activity in the early stages of the macaque visual system.
TLDR
In these early stages of the visual system, attention to the orientation of the grating suppressed the metabolic activity in a retinotopically specific band peripheral to the representation of the stimulus. Expand

TLDR
Results are inconsistent with the view that spatially selective processing in vision and audition is controlled by independent modality-specific systems and suggest that at post-perceptual levels, attentional control may be more flexible. Expand
Spatial gradients of visual attention: behavioral and electrophysiological evidence.
TLDR
Both d' scores and the amplitudes of the P135 and N190 waves decreased progressively as attention was directed to locations increasingly distant from a given lateral stimulus, which support 'gradient' models of the spatial distribution of visual attention. Expand
Parieto-occipital approximately 10 Hz activity reflects anticipatory state of visual attention mechanisms.
TLDR
High-density eeg recordings revealed sensory specific modulation of anticipatory parieto-occipital approximately 10 Hz oscillatory activity when visually presented word cues instructed subjects in an intermodal selective attention paradigm, and these results support models implicating parietoscipital areas in the directing and maintenance of visual attention.

ERP effects of intermodal attention and cross-modal links in spatial attention.
TLDR
The ERP effects of intermodal attention and of cross-modal links in spatial attention were investigated in two experiments where participants had to attend to one stimulus modality to respond to infrequently presented targets whenever these were presented at a relevant location (indicated by a cue). Expand
The neural mechanisms of top-down attentional control
TLDR
FMRI was used during a cued spatial-attention task to dissociate brain activity related to attentional control from that related to selective processing of target stimuli, indicating that Superior frontal, inferior parietal and superior temporal cortex were selectively activated by cues. Expand
