EEG waves {alpha wave} can have frequency range 8 to 12 per second. Sleep or quiet rest has alpha waves. They have larger amplitude if brain has pathology. A 12-millisecond phase shift goes from brain rostral to caudal pole, during alpha wave activity while awake and during REM sleep [Varela et al., 2001]. Alpha-wave frequency increases until five or six years old.
