Beta wave, or beta rhythm, is the term used to designate the
frequency range of
human brain activity between 12.5 and 30
Hz (12.5 to 30 transitions or cycles per second). Beta waves are split into three sections: Low Beta Waves (12.5–16 Hz, "Beta 1 power"); Beta Waves (16.5–20 Hz, "Beta 2 power"); and High Beta Waves (20.5–28 Hz, "Beta 3 power"). Beta states are the states associated with normal waking consciousness. Beta waves can be quantified using
Quantitative electroencephalography (qEEG) using freely available toolboxes, such as,
EEGLAB or the
Neurophysiological Biomarker Toolbox.
