Previous studies showed that neuronal network nuclei for behaviorally different forms of audiogenic seizure (AGS) exhibit similarities and important differences. The amygdala is involved differentially in tonic AGS as compared to clonic AGS networks. The role of the lateral amygdala (LAMG) undergoes major changes after AGS repetition (AGS kindling) in tonic forms of AGS. The present study examined the role of LAMG in a clonic form of AGS [genetically epilepsy-prone rats (GEPR-3s)] before and after AGS kindling using bilateral microinjection and chronic neuronal recordings. AGS kindling in GEPR-3s results in facial and forelimb (F&F) clonus, and this behavior could be blocked following bilateral microinjection of a NMDA antagonist (2-amino-7-phosphonoheptanoate) without affecting generalized clonus. Higher AP7 doses blocked both generalized clonus and F&F clonus. LAMG neurons in GEPR-3s exhibited only onset type neuronal responses both before and after AGS kindling, unlike LAMG neurons in normal rats and a tonic form of AGS. A significantly greater LAMG neuronal firing rate occurred after AGS kindling at high acoustic intensities. The latency of LAMG neuronal firing increased significantly after AGS kindling. Burst firing occurred during wild running and generalized clonic behaviors before and after AGS kindling. Burst firing also occurred during F&F clonus after AGS kindling. These findings indicate that LAMG neurons play a critical role in the neuronal network for generalized clonus as well as F&F clonus in GEPR-3s, both before and after AGS kindling, which contrasts markedly with the role of LAMG in tonic AGS.
