WebOct 9, 2024 · Beta activity refers to a frequency band rather than a distinct (specific) rhythm such as alpha or mu. Beta activity is commonly present in the EEG of healthy people. However, it is often difficult to see because of its low amplitude. Gastaut initially described the mu rhythm in 1952. Beta waves are often considered indicative of inhibitory cortical transmission mediated by gamma aminobutyric acid (GABA), the principal inhibitory neurotransmitter of the mammalian nervous system. Benzodiazepines, drugs that modulate GABAA receptors, induce beta waves in EEG recordings … See more Beta waves, or beta rhythm, are a neural oscillation (brainwave) in the brain with a frequency range of between 12.5 and 30 Hz (12.5 to 30 cycles per second). Beta waves can be split into three sections: Low Beta Waves … See more Beta waves were discovered and named by the German psychiatrist Hans Berger, who invented electroencephalography (EEG) in 1924, as a … See more Low-amplitude beta waves with multiple and varying frequencies are often associated with active, busy or anxious thinking and active concentration.
