Characteristics

Epilepsy-like behaviour which can be induced by Megamide (Nakano et al, 1996). Phenobarbital suppresses the seizures dose-dependently, but zonisamide is ineffective (Nagatomo et al, 1996a). Seizure susceptibility may be due to a reduced number of nitric oxide-producing cells in the hippocampal area (Nagatomo et al, 1996b) Maint. by Yok.
