[Early auditory evoked potentials (EAEP) following cochlear nerve lesions in the cerebellopontile angle. An animal experiment study]. 1983

H Mika, and K Maurer

After exposure of the cerebello-pontine angle, various lesions were applied to the cochlear nerve in 20 rabbits. Changes of the EAEP were registered at the same time. Lesions proximal to the internal auditory meatus hardly exercised any influence on wave I. Waves II-V disappeared immediately after the trauma, Partial or complete recovery was observed, depending on the extension of the nerve lesion. Dissection or crushing of the cochlear nerve resulted in permanent disappearance of the waves II-V. Wave I often showed a slight reduction of amplitude, combined with a broadening of its duration and increase in latency. Lesions of minor intensity produced a transient disappearance of waves II-V. Recovery of these waves occurred within the following 2-3 days.

D003056	Cochlear Nerve	The cochlear part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The cochlear nerve fibers originate from neurons of the SPIRAL GANGLION and project peripherally to cochlear hair cells and centrally to the cochlear nuclei (COCHLEAR NUCLEUS) of the BRAIN STEM. They mediate the sense of hearing.
