Is there frequency-specificity in the motor control of walking? The putative differential role of alpha and beta oscillations

open access: yesFrontiers in Systems Neuroscience, 2022
Alpha and beta oscillations have been assessed thoroughly during walking due to their potential role as proxies of the corticoreticulospinal tract (CReST) and corticospinal tract (CST), respectively.

Intra-cortical propagation of EEG alpha oscillations [PDF]

open access: yesNeuroImage, 2014
The most salient feature of spontaneous human brain activity as recorded with electroencephalography (EEG) are rhythmic fluctuations around 10Hz. These alpha oscillations have been reported to propagate over the scalp with velocities in the range of 5-15m/s. Since these velocities are in the range of action potential velocities through cortico-cortical

Alpha oscillation, criticality, and responsiveness in complex brain networks

open access: yesNetwork Neuroscience, 2020
Brains in unconsciousness are characterized by significantly limited responsiveness to stimuli. Even during conscious wakefulness, responsiveness is highly dependent on ongoing brain activity, specifically, of alpha oscillations (∼10 Hz). We hypothesized

Beta oscillations in vision: a (preconscious) neural mechanism for the dorsal visual stream?

open access: yesFrontiers in Psychology, 2023
Neural oscillations in alpha (8–12 Hz) and beta (13–30 Hz) frequency bands are thought to reflect feedback/reentrant loops and large-scale cortical interactions.

Computational analysis of speed-accuracy tradeoff

open access: yesScientific Reports, 2022
Speed-accuracy tradeoff (SAT) in the decision making of humans and animals is a well-documented phenomenon, but its underlying neuronal mechanism remains unclear. Modeling approaches have conceptualized SAT through the threshold hypothesis as adjustments

Vigilant attention mediates the association between resting EEG alpha oscillations and word learning ability

open access: yesNeuroImage, 2023
Individuals exhibit considerable variability in their capacity to learn and retain new information, including novel vocabulary. Prior research has established the importance of vigilance and electroencephalogram (EEG) alpha rhythm in the learning process.

Balance between pallidal neural oscillations correlated with dystonic activity and severity

open access: yesNeurobiology of Disease, 2023
Background and objective: The balance between neural oscillations provides valuable insights into the organisation of neural oscillations related to brain states, which may play important roles in dystonia.

Attention modulates TMS-locked alpha oscillations in the visual cortex [PDF]

open access: yes, 2015
Cortical oscillations, such as 8–12 Hz alpha-band activity, are thought to subserve gating of information processing in the human brain. While most of the supporting evidence is correlational, causal evidence comes from attempts to externally drive ...

Event-related alpha oscillations in task processing

open access: yesClinical Neurophysiology, 1999
Recent findings substantiate the view that electroencephalographic (EEG) alpha rhythm (7-13 Hz) is functionally involved in information processing. However, the association of alpha rhythms with cognitive brain processes is less well understood because both augmentation and suppression of alpha oscillations have been observed to accompany task ...

Resting-State Alpha-Band Oscillations in Migraine

open access: yesPerception, 2018
Migraine groups show differences in motion perception compared with controls, when tested in between migraine attacks (interictally). This is thought to be due to an increased susceptibility to stimulus degradation (multiplicative internal noise). Fluctuations in alpha-band oscillations are thought to regulate visual perception, and so differences ...
