| Research Abstract |
Applying freeze lesioning in the bilateral frontoparietal lobes during the prenatal period, we developed a cortical dysplasia rat model that can show spontaneous temporal lobe seizures. Immunohistochemical examinations using semiquantitative densitometry revealed the glutamine hyper-excitability at dysplasic lesion accelerate the hippocampal excitability. Phase locking analysis between dysplasic lesion and hippocampus showed the increment of synchronization between these two structures before the start of hippocampal seizure. These findings suggest the excitability in hippocampus increases gradually via the network between cortical dysplasia and hippocampus.
