Maturation Patterns of EEG Basic Waves of Healthy Infants under Twelve-months of Age

A simplified method for an evaluation of maturation patterns of the EEG waves of healthy infants under 12 months of age was reported. The EEG basic waves were divided into 10 bands according to frequency ranges (I-X bands). An averaged integrated voltage was calculated at each of the frequency bands (I-E%, II-E%, ....X-E%). When ‘R’=(E% of VIII+E% of IX)/(E% of II+E% of III) was claculated and plotted against the age in months, a linear figure was obtained which demonstrated a maturation pattern of the EEG basic waves of infants with advance in age.
