The development of EEG background activities in El mouse.

Abstract

The development of background activities of cortical EEG in El mouse, the seizure susceptible mutant strain of ddN mouse, were investigated. Furthermore, it was compared to that of the ddN control mouse. The average peak frequency of EEG background activity was much slower than that of the ddN mouse. After seizures in the El mouse were completed, the average energy distribution rates of the main frequency band, theta band, have decreased because of an increase in the delta band compared to those in seizure-free periods (the 5th to 8th week).
