Beta wave is the term used to designate the frequency range of brain activity above 12 Hz (12 transitions or cycles per second). Beta states are the states associated with normal waking consciousness. Low amplitude beta with multiple and varying frequencies is often associated with active, busy or anxious thinking and active concentration. Rhythmic beta with a dominant set of frequencies is associated with various pathologies and drug effects.
Beta Waves are also split into three sections. High Beta Waves(19Hz+) Beta Waves(15-18Hz) and Low Beta Waves(12-15Hz).
