The rhythms of spontaneously occurring seizures (spike-wave discharges, SWD) and motor activity, as well as the relationship between SWD and sleep-wake states were investigated in the WAG/Rij rat model of absence epilepsy. In order to establish whether SWD are controlled by external (Zeitgebers) or by endogenous factors such as circadian influences or the state of vigilance, the study was perfo...

The aim of this study is to analyze the graphic features and the clinical significance of the focal interictal paroxysmal abnormalities (FIPA) which can be found in the EEG of patients with typical absences, on the basis of 29 personal cases. The children (15 female; mean age at the first evaluation=8.2 years, range 4.8-14.3 years) were particularly selected, because they only showed absence se...
