In the past gamma waves were not researched to the same extent as the other four brain waves. Today they have gained more popularity and are known to be associated with perception and consciousness. Gamma waves can be between 26 and 70 Hz but most often corresponds to frequencies of 40 Hz or higher.
In medical and basic research, the correlation of particular brain waves with sleep phases, emotional states, psychological profiles, and types of mental activities is ongoing. Four simple periodic rhythms recorded in the EEG are alpha, beta, delta, and theta.These rhythms are identified by frequency (Hz or cycles/sec) and amplitude (Table 3.1). The amplitudes recorded by scalp electrodes are in the range of microvolts (uV or l/l,OOO,OOO of a volt).n medical and basic research, the correlation of particular brain waves with sleep phases, emotional states, psychological profiles, and types of mental activities is ongoing.
