Abstract

Sleep recordings were made some days before the occurrence of focal motor seizures in cats injected with alumina cream in the motor cortex. The wakefulness EEG was completely normal. Slow-wave sleep showed spike-spindles and occasional isolated spikes. During paradoxical sleep, abortive seizures appeared. They were only electrographic and never produced arousal of the animals. The precipitating role of phasic paradoxical sleep on focal motor seizures is proposed.
