Earliest recorded seizure activity at multiple sites in an epileptic pilocarpine-treated rat. A Seizure onset indicated by red dashed line. B Seizure 1 is an expanded view that reveals earliest recorded seizure activity in the left ventral subiculum. The high-amplitude background activity in the right ventral hippocampus should not be confused with the seizure onset. Seizures 2 and 3 show onsets of two other seizures recorded on another day. The earliest recorded seizure activity was in the right ventral subiculum of seizure 2 and the left dorsal hippocampus of seizure 3.
