The Electroencephalogram of the Healthy Person. Chapter III,
Abstract
The most characteristic feature of the human EEG, which distinguishes it from the EEG of animals, is the regular rhythmic activity, called the alpha rhythm, having a frequency of 8-12 oscillations per second, an amplitude of 50-100 microvolts and clearer manifestation in taps from the posterior sections of the hemispheres. The dominance of the alpha rhythm in the pattern of bioelectrical activity is typical for the brain of the healthy human adult in a state of relative rest. The rhythm of the biopotentials of the brain in infants is almost completely absent. The EEG evolves with age and as the nerve elements mature, the oscillation frequency gradually increases, a more or less stable rhythm develops and an EEG pattern, typical for the adult human, is established by 14 to 16 years of age.
