Absence seizures do not result in severe postictal hypoxia. (a) 198 seizures were recorded from 5 GAERS rats. Distribution of seizure durations from all seizure events. (b) Mean neocortical oxygen profile (n = 5) during 30-minute recording sessions. Mean oxygen did not fall below the severe hypoxic threshold, despite the occurrence of 198 absence seizures. (c), Mean hippocampal oxygen profile (n = 3) following elicitation of a single, brief seizure with 60 Hz kindling stimulation (first and only kindling session). Mean oxygen crossed the severe hypoxic threshold in the postictal period.
