title: Effects of stimulation of the primary auditory cortex upon colliculogeniculate neurons in the inferior colliculus of the cat.
abstract: Electrical stimulation of the primary auditory cortex (AI) of the cat was found to evoke EPSPs, IPSPs or EPSP-IPSP sequences in colliculogeniculate (CG) neurons in the inferior colliculus (IC) which responded antidromically to stimulation of the medial geniculate nucleus. The CG neurons responding to the AI stimulation with short-latency EPSPs (1.0-1.4 msec) were located in the dorsomedial portion of the central nucleus of the IC. On the other hand, latencies of IPSPs elicited in CG neurons by AI stimulation ranged from 2.0 to 4.5 msec.
