Brain networks and α-oscillations: structural and functional foundations of cognitive control
S Sadaghiani, A Kleinschmidt - Trends in cognitive sciences, 2016 - cell.com
The most salient electrical signal measured from the human brain is the α-rhythm, neural
activity oscillating at∼ 100ms intervals. Recent findings challenge the longstanding dogma …

Alpha synchrony and the neurofeedback control of spatial attention
Decreases in alpha synchronization are correlated with enhanced attention, whereas alpha
increases are correlated with inattention. However, correlation is not causality, and …

Activation of serotonin 2A receptors underlies the psilocybin-induced effects on α oscillations, N170 visual-evoked potentials, and visual hallucinations
Visual illusions and hallucinations are hallmarks of serotonergic hallucinogen-induced
altered states of consciousness. Although the serotonergic hallucinogen psilocybin activates …

Cortical alpha oscillations as a tool for auditory selective inhibition
A Strauß, M Wöstmann, J Obleser - Frontiers in human neuroscience, 2014 - frontiersin.org
Listening to speech is often demanding because of signal degradations and the presence of
distracting sounds (ie,“noise”). The question how the brain achieves the task of extracting …

Laminar profile and physiology of the α rhythm in primary visual, auditory, and somatosensory regions of neocortex
The functional significance of the α rhythm is widely debated. It has been proposed that α
reflects sensory inhibition and/or a temporal sampling or “parsing” mechanism. There is also …

Region-specific modulations in oscillatory alpha activity serve to facilitate processing in the visual and auditory modalities
There have been a number of studies suggesting that oscillatory alpha activity (~ 10 Hz)
plays a pivotal role in attention by gating information flow to relevant sensory regions. The …
