[Distribution of metabolic activity (cytochrome oxidase) and immunoreactivity to calcium-binding proteins in turtle brainstem auditory nuclei].
Using histochemical and immunohistochemical techniques, distribution of activity of oxidative mitochondrial enzyme cytochrome oxidase (CO) and of immunoreactivity to calcium-binding proteins has been studied in spiral ganglion and auditory nuclei of brainstem in two turtle species. It has been shown that immunoreactivity to calbindin, parvalbumin, and calretinin in neurons and neuropil of nuclei of cochlear and superior olivary complexes, in nucleus of lateral lemniscus, and in spiral ganglion neurons coincides topographically with the high CO activity. The similarity of the studied metabolic and neurochemical characteristics of these auditory centers in reptiles, birds, and mammals indicates the existence of some common principles of their organization in amniotes in spite of phylogenetic differences and peculiarities of specialization of the auditory system in different species.
