Abstract:
Seizures induced in rats by kainic acid microinjection into the perirhinal cortex were studied electrophysiologically and behaviorally and compared with known features of seizures following kainic acid injection into the amygdala. Unlike amygdalar seizures, perirhinal cortical seizures did not generalize to become limbic seizures but rather spread to sensorimotor cortex to become manifest as motor seizures. Perirhinal cortical seizures also required larger kainic acid doses for provocation and were briefer.
