Summated auditory evoked potentials in the cerebellum and inferior colliculus in the young rat

The summated auditory evoked responses recorded at the superior surface and depth of the cerebellum of the young rat had a similar latency and configuration as did summated auditory evoked potentials in the inferior colliculus. Electric stimulation of the inferior colliculus did not evoke a response (other than the shock-artifact response) at the cerebellum. Stimulation of the cerebellum did not modify the evoked responses to click in the inferior colliculus (unless current levels were large enough to cause current spread to the brain stem). There is insufficient evidence to conclude that the cerebellum has an auditory receiving area in the young rat.
