Effect of penicillin‐induced epilepsy seizure on the volume of hippocampus stratum pyramidalis in rat

Experimental epileptic models have been developed to assess the pathophysiology of epileptic seizures. We have previously shown that epileptic seizures cause significant neuronal loss in hippocampus (p 0.05). This study suggests that the loss of hippocampal neurons in penicillin-induced epilepsy seizure is not directly correlated with a volume change in the hippocampus. Furthermore, our results indicate that it is important to assess both the neuron number and the volume of the affected area using stereological methods in an epilepsy model to objectively analyze the effects of the seizure.
