Webtheta (4-12 Hz) and gamma (40-90) oscillations are prominent rhythms in the mammalian brain. A striking feature of these rhythms, possibly vital to memory encoding, is their specific coordination in a manner that has been termed 'nesting', i.e. the preferred occurrence of bouts of gamma activity during specific phases of theta. crystal uplightWebDuring relaxed wakefulness, the human brain exhibits pronounced rhythmic electrical activity in the alpha frequency band (8-13 Hz).
