Abstract

Fos-like immunoreactivity (FLI) was mapped in the auditory pathway ofSprague-Dawley rats in response to unilateral electrical stimulation of the cochlea implanted with two stimulating electrodes. Densely packed FLI neurons were widely distributed in the dorsal cochlear nucleus (more ipsilaterally than contralaterally), while FLI neurons were rarein the posteroventral cochlear nucleus and virtually absent in the anteroventral cochlear nucleus. Sparse FLI was detected in the superior olivary complex, the pontine nuclei and the ipsilateral dorsal nucleusof the lateral lemniscus, whereas the contralateral dorsal nucleus ofthe lateral lemniscus was moderately labeled. In the inferior colliculus, the pattern of FLI was similar on both sides, restricted mainly to its dorsal and external cortices. At the thalamic level, FLI neuronswere seen in the dorsal and medial divisions of the medial geniculatebody as well as in the peripeduncular nucleus. A significant increaseof FLI was observed in the temporal cortex. This study demonstrates the presence of selective functional changes along the auditory pathwayelicited by electrical stimulation of the cochlea, as revealed by FLI.
