The effects of bilateral high radiofrequency lesions of superior colliculus (SC) were studied on amygdala kindling. The results demonstrate that a selective destruction of the SC only slightly facilitated the development of kindling. However, the most remarkable effect was the increase of afterdischarge and motor seizure duration observed when SC-lesioned animals reached the generalized seizures. These data confirm that the superior colliculi participate in controlling the generalization of kindled seizures.
