Attention enhances LFP phase coherence in macaque visual cortex, improving sensory processing

TLDR
The data reveal that phase coherence increases when attention is deployed towards the receptive field of the recorded neural population, and it is shown that the attentional enhancement ofphase coherence is positively correlated with the Attentional modulation of stimulus induced firing rate, and importantly, a higher phase coherent leads to a faster behavioral response.

Using Neuronal Populations to Study the Mechanisms Underlying Spatial and Feature Attention

High-alpha band synchronization across frontal, parietal and visual cortex mediates behavioral and neuronal effects of visuospatial attention

Spectral and Anatomical Patterns of Large-Scale Synchronization Predict Human Attentional Capacity.

TLDR
The results show that good attentional capacity is preceded by efficient dynamic functional coupling and decoupling within brain regions and across frequencies, which may enable efficient communication and routing of information between sensory and attentional systems.

Spatial attention modulates visual gamma oscillations across the human ventral stream

Attention strengthens across-trial pre-stimulus phase coherence in visual cortex, enhancing stimulus processing

TLDR
This work documents an attentional modulation of pre-stimulus inter-trial phase coherence of low frequency local field potentials (LFP) in visual area MT of macaque monkeys and reveals that phase coherent increases following a spatial cue deploying attention towards the receptive field of the recorded neural population.

Spatial attention increases high-frequency gamma synchronisation in human medial visual cortex

Top-down flow of visual spatial attention signals from parietal to occipital cortex.

TLDR
This work test the hypothesis that topographically organized posterior parietal cortical areas IPS1 and IPS2 transmit top-down spatial attention signals to early visual cortex and measures functional connectivity among cortical areas V1, V2, V3, V4, V5, V6, and IPS1 during sustained visual spatial attention to measure coherency.

Early dissociation between neural signatures of endogenous spatial attention and perceptual awareness during visual masking

TLDR
The results support a double dissociation between the neural signatures of endogenous spatial attention and perceptual awareness, suggesting that the conscious detection of a masked stimulus at an unexpected location captures spatial attention.

Temporal Dynamics and Response Modulation across the Human Visual System in a Spatial Attention Task: An ECoG Study

The selection of behaviorally relevant information from cluttered visual scenes (often referred to as “attention”) is mediated by a cortical large-scale network consisting of areas in occipital,…

Modulation of long-range neural synchrony reflects temporal limitations of visual attention in humans.

TLDR
This work hypothesized that the network communicates by means of neural phase synchronization, and used magnetoencephalography to study transient long-range interarea phase coupling in a well studied attentionally taxing dual-target task (attentional blink).

α-Band Electroencephalographic Activity over Occipital Cortex Indexes Visuospatial Attention Bias and Predicts Visual Target Detection

TLDR
Electroencephalography data indicate that collateral modulations of posterior α-activity, the momentary bias of visuospatial attention, and imminent visual processing are linked, and suggest that the Momentary direction of attention, predicting spatial biases in imminent visualprocessing, can be estimated from a lateralization index of posterior β-activity.

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.

Attentional modulation in visual cortex depends on task timing

TLDR
The attentional modulation of sensory neurons reflects a subject's anticipation of the timing of behaviourally relevant events and is shown to reflect the allocation of attention over time.

Brain signals for spatial attention predict performance in a motion discrimination task.

TLDR
It is shown that subjects' performance can be predicted, trial-by-trial, by neural activity that precedes the onset of a sensory stimulus and that BOLD signals can be used to forecast human behavior.

Increased Activity in Human Visual Cortex during Directed Attention in the Absence of Visual Stimulation

Anticipatory Biasing of Visuospatial Attention Indexed by Retinotopically Specific α-Bank Electroencephalography Increases over Occipital Cortex

TLDR
Alpha-band (8-14 Hz) oscillatory EEG activity was examined with high-density scalp electrical recording during the cue-stimulus interval of an endogenous spatial cueing paradigm and results are consistent with active gating of uncued spatial locations.

Selective visual attention and perceptual coherence

Mechanisms of visual attention in the human cortex.

TLDR
Functional brain imaging studies reveal that, both in the absence and in the presence of visual stimulation, biasing signals due to selective attention can modulate neural activity in visual cortex in several ways.
