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.
研究发现，电刺激猫的初级听觉皮层（AI）能在下丘（IC）的丘膝神经元（CG）中诱发兴奋性突触后电位（EPSP）、抑制性突触后电位（IPSP）或EPSP-IPSP序列，这些神经元对内侧膝状体核的刺激产生逆行反应。以短潜伏期EPSP（1.0-1.4毫秒）对AI刺激作出反应的CG神经元位于IC中央核的背内侧部分。另一方面，AI刺激在CG神经元中诱发的IPSP潜伏期为2.0至4.5毫秒。
