Developmental change of EEG in rat from 4th to 16th week.
The development of EEG in 8 male rats from 4 to 16 weeks age were studied chronically. Theta band had the highest power at 5--16 weeks. Especially after 11 weeks, theta band presented a significantly higher peak than that of 4-week-old. In contrast to this, delta band, which had the highest power at 4 weeks, was markedly decreased.
