Frequency-specific transcranial neuromodulation of oscillatory alpha power alters and predicts human visuospatial attention performance

A leftward lateralization of alpha power relative to sham and a leftward attention bias are observed, which suggest that tACS operates through oscillatory interactions with ongoing brain rhythms in line with the synchronization theory.

Cortical dynamics following real-time MEG neurofeedback training of the speed of shifting spatial attention: a pilot study

A significant main effect of training is found on the reaction time linked to switching spatial attention in both the training task and the validation task, indicating the achieved improvement in shifting spatial attention generalized to another situation requiring this capability.

Short-delay neurofeedback facilitates training of the parietal alpha rhythm

It is shown for the first time show that visual NFB of parietal EEG alpha-activity is efficient only when delivered to human subjects at short latency, which guarantees that NFB arrives when an alpha spindle is still ongoing.

The neural bases of spatial attention and perceptual rhythms

A rhythmic and continuous model of attentional sampling is proposed, showing that attention involves a continuous exploration of space, shifting within and across visual hemifield at specific alpha and theta rhythms, independently of the current attentional load.

The importance of being on time: delayed neurofeedback impedes training of the parietal alpha-band power

It is shown that NFB latency affects the ability of subjects to increase their parietal electroencephalographic alpha activity, and clinical practitioners and manufacturers of NFB equipment should include latency in their specifications, and enable short-latency operations.

On the Role of Prestimulus Alpha Rhythms over Occipito-Parietal Areas in Visual Input Regulation: Correlation or Causation?

The test in the human brain whether the oscillation in the alpha band is causally shaping perception through directly stimulating visual areas via short trains of rhythmic TMS shows that the posterior alpha rhythm is actively involved in shaping forthcoming perception and, hence, constitutes a substrate rather than a mere correlate of visual input regulation.

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

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.

The Role of Alpha-Band Brain Oscillations as a Sensory Suppression Mechanism during Selective Attention

Findings in the context of intersensory selective attention as well as intrasensory spatial and feature-based attention in the visual, auditory, and tactile domains are discussed.

Neurofeedback Training of Gamma Oscillations in Monkey Primary Visual Cortex.

Both monkeys succeeded to raise gamma activity in the absence of visual stimulation in the selected frequency band and at the site from which the NFB signal was derived, suggesting that top-down signals are not confined to just modulate stimulus induced responses but can actually drive or facilitate the gamma generating microcircuits even in a primary sensory area.

Endogenously generated gamma‐band oscillations in early visual cortex: A neurofeedback study

It is argued that spatially confined networks in early visual cortex can be entrained to engage in narrow band gamma oscillations not only by visual stimuli but also by top down signals.

Neuronal Mechanisms and Attentional Modulation of Corticothalamic Alpha Oscillations

Analyzing laminar profiles of local field potential and multiunit activity recorded with linear array multielectrodes from the striate cortex of two macaque monkeys found that visual attention reduces the magnitude of alpha oscillations as well as the level of alpha interactions, consistent with numerous reports of occipital alpha reduction with visual attention in human EEG.
