5Hz - 4Hz high (up to 200uV) Deep sleep Theta 4Hz - 8Hz low (5uV - 20uV) somnolence (also first stage of sleep) Alpha 8Hz - 14Hz high (up to 200uV) Relaxed but rakish Bet a 14Hz - 30Hz low (less than 10uV) Highly alert and focused The predominate absolute frequency in the EEG pattern determines what shall be called the modish state of the brain.
