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. In different blocks, cued spatial locations (left or right) were in either the upper or lower visual field, and attended stimuli were either oriented Ts or moving dots. Distractor stimuli were equally likely in the uncued hemifield. Sustained focal increases of alpha-band activity were seen over occipital cortex…

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.
Right Prefrontal TMS Disrupts Interregional Anticipatory EEG Alpha Activity during Shifting of Visuospatial Attention
TLDR
Visual attention processes associated with posterior EEG alpha activity are at least partly top-down controlled by the prefrontal cortex, according to a multimodal approach combining transcranial magnetic stimulation and multichannel electroencephalography in healthy humans.
Frontoparietal Cortex Controls Spatial Attention through Modulation of Anticipatory Alpha Rhythms
TLDR
The causal role of the dorsal frontoparietal network is supported in the control of visuospatial attention, and it is suggested that this is partly exerted through the synchronization of occipital visual neurons.
Shifting visual attention away from fixation is specifically associated with alpha band activity over ipsilateral parietal regions.
TLDR
Brain activity during the displacement of attention in a modified visuo-spatial orienting paradigm revealed an attention directing anterior negativity contralateral to the shift of attention and P3 and contingent negative variation waveforms that were enhanced in both shift conditions as compared to the no-shift task.
A shift of visual spatial attention is selectively associated with human EEG alpha activity
TLDR
It was found that prefrontal cortex shows stronger phase coupling with posterior sites that are contralateral to the attended hemifield than ipsilateral sites, and that this posterior modulation of alpha activity is controlled by prefrontal regions.

Lateralization of posterior alpha EEG reflects the distribution of spatial attention during saccadic reading.
TLDR
The use of EEG alpha-band oscillations to investigate the spatial distribution of attention during reading indicates that alpha lateralization can serve as a measure of attention deployment and its link to oculomotor behavior in reading.
Lateralization in Alpha-Band Oscillations Predicts the Locus and Spatial Distribution of Attention
TLDR
The results suggest that alpha synchronization reflects changes in the excitability of populations of neurons whose receptive fields match the locus of attention, consistent with the hypothesis that alpha oscillations reflect the neural mechanisms by which top-down control of attention biases information processing and modulate the activity of neurons in visual cortex.
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.
Spontaneous Alpha Power Lateralization Predicts Detection Performance in an Un-Cued Signal Detection Task
TLDR
The results support the presence of a spontaneous component of visuospatial attentional allocation and they advance pre-stimulus alpha-band lateralization as one of its neural signatures.

Electroencephalographic activity associated with shifts of visuospatial attention.
TLDR
Different ERP patterns generated by central and peripheral cues support the hypothesis that distinct neural systems are involved in voluntary and reflexive mechanisms of attention shift and suggest that the neural processes underlying spatial selection are initiated in the posterior region and that other cortical activities are recruited in a serial fashion.
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.

Neural Processes Involved in Directing Attention
TLDR
Boys appeared more aroused and reflected faster and greater selective processing than girls than girls and the effects of spatial attention on P1, N1, and P3 ERP components following the targets replicated previous results.

Modulation of the Parieto-Occipital Alpha Rhythm during Object Detection
TLDR
The results reinforce the idea of bidirectional interaction: information derived from visual shape can rapidly modify activity in the parieto-occipital region, and synchronized alpha oscillations may reflect attenuation of occipito-parietal information transfer and disengagement of parietal cortex from object selection.
