title: [Effect of cerebral hypoxia and hyperventilation hypocapnia on the epileptiform activity of the cerebral cortex of the cat].
abstract: Influence of cerebral hypoxia and hyperventilatory hypocapnia on the ECoG and focal epileptiform activity of the cerebral cortex induced with local application of strychnine was studied in cats with transection of spinal cord at C1. Although both hypoxia and hypocapnia produced synchronization of the cerebral cortex electrical activity, i.e. exerted the same effects on the ECoG, their influence on cortical excitability was quite different: hypoxia suppressed the epileptiform activity whereas hypocapnia facilitated it.
