Alterations of the alpha rhythm in visual snow syndrome: a case-control study [PDF]

open access: yesThe Journal of Headache and Pain
Background Visual snow syndrome is a disorder characterized by the combination of typical perceptual disturbances. The clinical picture suggests an impairment of visual filtering mechanisms and might involve primary and secondary visual brain areas, as ...

The generation and propagation of the human alpha rhythm. [PDF]

open access: yesProc Natl Acad Sci U S A, 2019
Abstract The alpha rhythm is the longest studied brain oscillation and has been theorized to play a key role in cognition. Still, its physiology is poorly understood. In this study, we used micro and macro electrodes in surgical epilepsy patients to measure the intracortical and thalamic generators of the alpha rhythm during quiet ...

Portable wireless neurofeedback system of EEG alpha rhythm enhances memory [PDF]

open access: yesBioMedical Engineering OnLine, 2017
Background Effect of neurofeedback training (NFT) on enhancement of cognitive function or amelioration of clinical symptoms is inconclusive. The trainability of brain rhythm using a neurofeedback system is uncertainty because various experimental designs

Effect of Pilates training on alpha rhythm. [PDF]

open access: yesComput Math Methods Med, 2013
In this study, the effect of Pilates training on the brain function was investigated through five case studies. Alpha rhythm changes during the Pilates training over the different regions and the whole brain were mainly analyzed, including power spectral density and global synchronization index (GSI).

Dynamics of the EEG sensorimotor and alpha rhythm amplitude patterns in a training series of controlling the power platform with visual feedback [PDF]

open access: yesSHS Web of Conferences, 2019
The study of the EEG alpha reactivity patterns in the prefrontal, central, parietal and occipital regions involved 25 healthy male subjects who participated in four training sessions of controlling the power platform with visual feedback.

Never resting brain: simultaneous representation of two alpha related processes in humans. [PDF]

open access: yesPLoS ONE, 2008
Brain activity is continuously modulated, even at "rest". The alpha rhythm (8-12 Hz) has been known as the hallmark of the brain's idle-state. However, it is still debated if the alpha rhythm reflects synchronization in a distributed network or focal ...

Alpha-band rhythms in visual task performance: phase-locking by rhythmic sensory stimulation [PDF]

open access: yes, 2012
Oscillations are an important aspect of neuronal activity. Interestingly, oscillatory patterns are also observed in behaviour, such as in visual performance measures after the presentation of a brief sensory event in the visual or another modality. These

The dynamic of brain rhythms after neurofeedback course

open access: yesБюллетень сибирской медицины, 2010
In this article there is comparative analysis of cerebrum biopotentials of sportsmen in different periods after the end of neurofeedback course. It was revealed the character of late effects has depended on success of the training and period it’s end ...

Alpha Rhythms and Hyperkinesis [PDF]

open access: yesNature, 1973
IN his comment on my report “Alpha Rhythms in the Hyperkinetic Child”1, Davidson2 stated that my data support Lippold's hypothesis3 that “Oscillation in striate muscle control systems is the source of alpha rhythm”. He quoted the work of Mulholland and Evans4,5 which suggested that presence or absence of alpha rhythms was not determined by the presence
