Effects of zonisamide (AD-810, CI-912) were examined on tungstic acid gel-induced thalamic generalized seizures and conjugated estrogen-induced cortical spike-wave discharges in gallamine-immobilized cats. Zonisamide prolonged the interictal periods of the generalized seizures by thalamic (centralis lateralis) application of tungstic acid
