The functional roles of alpha-band phase synchronization in local and large-scale cortical networks
Frontiers in Psychology, 2011 Alpha-frequency band (8-14 Hz) oscillations are among the most salient phenomena in human electroencephalography (EEG) recordings and yet their functional roles have remained unclear.

Frontiers in Pharmacology, 2022 Background: Electroencephalography (EEG) recordings under propofol exhibit an increase in slow and alpha oscillation power and dose-dependent phase–amplitude coupling (PAC), which underlie GABAA potentiation and the central role of thalamocortical ...

Attentional switching-related human EEG alpha oscillations
Neuroreport, 2002 Alpha oscillations during cognitive performance have mostly been studied in memory and/or basic attention tasks. This study investigates task-related alpha power desynchronization during an attentional switching task requiring higher executive attentional control.

Do spherical alpha^2-dynamos oscillate?
, 2002 The question is answered whether kinematic alpha^2-shell-dynamos are able to produce a cyclic activity or not. The alpha-effect is allowed to be latitudinally inhomogeneous and/or anisotropic, but it is assumed as radially uniform in the turbulent shell.

Dynamic Neural State Identification in Deep Brain Local Field Potentials of Neuropathic Pain
Frontiers in Neuroscience, 2018 In neuropathic pain, the neurophysiological and neuropathological function of the ventro-posterolateral nucleus of the thalamus (VPL) and the periventricular gray/periaqueductal gray area (PVAG) involves multiple frequency oscillations.

Alpha oscillations in brain functioning: an integrative theory
International Journal of Psychophysiology, 1997 The old concept stating that EEG alpha (10-Hz) activity reflects passive or idling states of the brain is giving way to modern views of 10-Hz oscillations in relation to diverse brain functions comprising sensory, motor, and memory processes: (1) Spontaneous alpha activity is not pure noise as shown by methods of chaos analysis.

Distinct roles of forward and backward alpha-band waves in spatial visual attention
eLife, 2023 Previous research has associated alpha-band [8–12 Hz] oscillations with inhibitory functions: for instance, several studies showed that visual attention increases alpha-band power in the hemisphere ipsilateral to the attended location.

Tactile expectancy modulates occipital alpha oscillations in early blindness
NeuroImage, 2023 Alpha oscillatory activity is thought to contribute to visual expectancy through the engagement of task-relevant occipital regions. In early blindness, occipital alpha oscillations are systematically reduced, suggesting that occipital alpha depends on ...
