Beta wave

Beta waves were discovered and named by the German psychiatrist Hans Berger, who invented electroencephalography (EEG) in 1924, as a method of recording electrical brain activity from the human scalp.

[6] Bursts of beta activity are associated with a strengthening of sensory feedback in static motor control and reduced when there is movement change.

[11] During rest, fast beta oscillations are prevalent over lateral prefrontal cortex (LPFC) in humans, following a posteroanterior increase in frequency.

Benzodiazepines, drugs that modulate GABAA receptors, induce beta waves in EEG recordings from humans [14] and rats.

[16] Similarly, children with Angelman syndrome with deletions of the same GABAA receptor subunit genes feature diminished beta amplitude.
