Beyond pulsed inhibition: Alpha oscillations modulate attenuation and amplification of neural activity in the awake resting state

open access: yesCell Reports, 2023
Summary: Alpha oscillations are a distinctive feature of the awake resting state of the human brain. However, their functional role in resting-state neuronal dynamics remains poorly understood.

Somatosensory alpha oscillations gate perceptual learning efficiency [PDF]

open access: yesNature Communications, 2019
Alpha power is known to play an important role in cognition and perception, but we do not understand the link between alpha power and perceptual learning efficacy.

Object-based attentional selection modulates anticipatory alpha oscillations [PDF]

open access: yesFrontiers in Human Neuroscience, 2015
Visual cortical alpha oscillations are involved in attentional gating of incoming visual information. It has been shown that spatial and feature-based attentional selection result in increased alpha oscillations over the cortical regions representing ...

Functional aspects of alpha oscillations in the EEG

open access: yesInternational Journal of Psychophysiology, 2001
Experimental evidence suggests a functional significance of EEG alpha rhythms. Event-related, evoked, and induced alpha rhythms may have functional correlates in primary sensory processing and preparatory processes. These results are in accordance with the view that spontaneous and induced EEG alpha rhythms have quasi-deterministic properties.

The role of alpha oscillations in resisting distraction

open access: yesTrends in Cognitive Sciences
The role of alpha oscillations (8-13 Hz) in suppressing distractors is extensively debated. One debate concerns whether alpha oscillations suppress anticipated visual distractors through increased power. Whereas some studies suggest that alpha oscillations support distractor suppression, others do not.

Attentional tracking reduces cortical alpha oscillations

open access: yesScientific Reports
The premotor theory of attention suggests that both overt and covert attentional orienting are governed by similar mechanisms and neural structures, a concept extensively investigated in paradigms involving shifts in attention and gaze towards peripheral

Alpha oscillations modulate premotor-cerebellar connectivity in motor learning: Insights from transcranial alternating current stimulation

open access: yesNeuroImage, 2021
Alpha oscillations (8-13 Hz) have been suggested to play an important role in dynamic neural processes underlying learning and memory. The goal of this study was to scrutinize the role of alpha oscillations in communication within a cortico-cerebellar ...

Experimental placebo analgesia changes resting-state alpha oscillations. [PDF]

open access: yesPLoS ONE, 2013
The lack of clear understanding of the pathophysiology of chronic pain could explain why we currently have only a few effective treatments. Understanding how pain relief is realised during placebo analgesia could help develop improved treatments for ...
