Epileptiform patterns observed in traumatic brain injury (TBI) rats at 1 min before the initiation of an electrographic seizure. Y-axis shows the behavioral severity of each seizure on Racine's scale. (A) Rat #1049 that had 56 seizures over a period of 40 h. Epileptiform activity largely comprised generalized continuous spiking (GCS; see Fig. 7). (B) Rat #1059 had 39 seizures over a period of 156 h. Preictal epileptiform activity largely comprised periodic discharges (PDs), GCS, spikes (SPk) and polyspikes (PSPk), suppression (Supp), and rhythmic occipital intermittent delta activity (OIRDA). (C) Percentage of different electrographic patterns preceding the electrographic seizure in rats with TBI. Color image is available online.
