[Effects of cochlear implant on the morphofunctional state of spiral ganglion neurocytes].

This paper discusses the effects of cochlear implantation on spiral ganglion neurocytes. It presents morphometric data and hearing measurements obtained from the treated animals. Cochlear implantation led to the death of some neurons and compensatory rearrangement of others. The number of the survivors was greater than that of degenerative cells. The functional variations were consistent with changes in the quality of spiral ganglion neurons and amplitude of the SSP EP peak at different postoperative intervals.
