Earliest recorded seizure activity in the ventral hippocampus. A Seizure onset indicated by red dashed line. B Expanded view reveals earliest seizure activity in the right ventral hippocampus. C Nissl-stained section reveals long (arrow) and short parts of a bipolar electrode track (double arrow). The short electrode recorded the earliest seizure activity 118 times, which was 96% of all seizures recorded earliest in the right ventral hippocampus and 63% of all seizures recorded in this rat. m = molecular layer, g = granule cell layer, h = hilus, S = subiculum.
