title: The effect of the destruction of the caudate-putamen on the development of amygdaloid kindling and kindled seizures.
abstract: To elucidate the possible roles of the caudate-putamen (CP) on the development of amygdala (AM) kindling and AM-kindled seizures, the bilateral CP were destroyed by intra-CP injection of ibotenic acid (0.5 or 1.0 microg per side) before the AM kindling or after completion of the AM kindling. Prior destruction of the CP, especially by 0.5 microg ibotenic acid injection, caused a significant delay in seizure development. However, after completion of the AM kindling, bilateral destruction of the CP significantly suppressed AM-kindled seizures in proportion to lesion size, however, all animals reached a stage 5 seizure by additional stimulations and established AM kindling. These findings suggest that the intact CP modulates the development of the AM kindling and the generalization and/or expression of the kindled AM seizures, and that the CP plays an important role in the generalization and/or expression of the kindled AM seizures.
