Abstract In an explorative study, we investigated the time course of attentional selection shifts in feature-based attention in early visual cortex by means of steady-state visual evoked potentials (SSVEPs). To this end, we presented four flickering random dot kinematograms with red/blue, horizontal/vertical bars, respectively. Given the oscillatory nature of SSVEPs, we were able to investigate neural temporal dynamics of facilitation and inhibition/suppression when participants shifted…

Suppression of Unattended Features Is Independent of Task Relevance.
TLDR
Electroencephalography-derived steady-state visual-evoked potentials were used to investigate early visual processing of the attended, unattended, and irrelevant color under sustained feature-based attention and revealed a biphasic process with an early amplification of the to-be-attended color followed by suppression ofThe neural dynamics for the unattended and always irrelevant color were comparable.

Time matters: Feature-specific prioritization follows feature integration in visual object processing
TLDR
A novel experimental design was employed, allowing simultaneous electrophysiological measurements of the allocation of attention to two distinct features within one object (a square) during both trial-wise and block-wise cued shifts of attention, which indicated a biphasic process composed of an early transient integration of the constituent object features, followed by sustained mechanisms of feature selection with amplification of the to-be-attended feature, followed temporally by suppression of the new feature.
Early Visual Cortex Dynamics during Top–Down Modulated Shifts of Feature-Selective Attention
TLDR
It is found that shifts toward color occurred earlier after the shifting cue compared with shifts toward orientation, regardless of the original feature (i.e., color or orientation), which was paralleled in SSVEP amplitude modulations as well as in the time course of behavioral data.
Global Enhancement but Local Suppression in Feature-based Attention
TLDR
Results showed amplification of the attended and suppression of the unattended color as measured by SSVEP amplitudes, indicating that, while facilitation in feature-based attention operates globally, suppression seems to be linked to the location of focused attention.
Behavioral performance follows the time course of neural facilitation and suppression during cued shifts of feature-selective attention
TLDR
The significant deviations from a temporally synchronized reciprocity between enhancement and suppression suggest that the enhancement of the attended stimulus may cause the suppression of the unattended stimulus in the present experiment.
Spatial Attentional Selection Modulates Early Visual Stimulus Processing Independently of Visual Alpha Modulations.
TLDR
The results challenge the view that modulations of alpha-band activity represent a mechanism that directly alters or controls sensory gain and the potential role ofalpha-band oscillations beyond sensory processing is discussed.
Dynamics of Feature-based Attentional Selection during Color–Shape Conjunction Search
TLDR
The results suggest that target-colored objects are prioritized during color–shape conjunction search, and the ability to select the target is delayed while target- colored distractors are actively suppressed.
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.
Selective attention to stimulus location modulates the steady-state visual evoked potential.
TLDR
These findings indicate that the SSVEP reflects an enhancement of neural responses to all stimuli that fall within the "spotlight" of spatial attention, whether or not the stimuli are task-relevant.
Putting spatial attention on the map: timing and localization of stimulus selection processes in striate and extrastriate visual areas
TLDR
The cortical mechanisms of visual-spatial attention in a task where subjects discriminated patterned targets in one visual field at a time were investigated to localize attention-related changes in neural activity within specific retinotopic visual areas, while recordings of event-related brain potentials (ERPs) traced the time course of these changes.
Visual search for singleton feature targets across dimensions: Stimulus- and expectancy-driven effects in dimensional weighting.
TLDR
Findings confirm that top-down dimensional set modulates stimulus-driven dimension processes in the detection of pop-out signals.
