Zusammenfassung: | Aspartate aminotransferase and glutaminase immunoreactive labeling of the auditory nerve has previously been reported. In the present study, the development of these immunoreactivities was examined in the auditory nerve of the rat, at ages ranging from 17 days gestation to four postnatal weeks. Cells and processes were examined in the cochlea, and fibers and terminals in the cochlear nucleus. In the cochlea, immunoreactive labeling with antisera to both enzymes was first seen at 20 gestational days, in spiral ganglion cells. It was not until two postnatal weeks, however, that this immunoreactive labeling was first seen in primary afferent terminals around spherical cells in the anteroventral cochlear nucleus. This correlates with the establishment of mature synaptic connections and function. |
