[Effect of chronic electric stimulation of the auditory nerve on the development of the cochlear nuclei in guinea pigs].

14 newborn guinea pigs have been deafened three days after birth by bilateral destruction of the organ of Corti, and among them 8 have been supplied with a chronic auditory electric stimulation by mean of an intra-cochlear implanted electrode. The histological study and the anatomical reconstructions of these animals' cochlear nuclei demonstrate that this chronic stimulation prevent at least partially these auditory pathway medullary formations from the atrophy due to the cochlear destruction.
