title: [Parenteral penicillin in rats: an experimental model of periodic EEG activity].
abstract: Parenteral G Penicillin has been administered to 10 rats and EEG pattern has been recorded. High voltage spikes appeared on one hemisphere, 12 to 25 minutes after injections. Gradually spike frequency and voltage increased till periodical EEG was observed  on both hemispheres. Such activity was synchronous, symmetrical, stereotyped and often accompanied by myoclonias. This pattern lasted from 45 to 100 minutes. The authors underline the analogies with the Ouabain model of epilepsy and with periodical EEG patterns in man.
