Histochemical and fluorescent analyses of mitochondrial integrity in chick auditory neurons following deafferentation.

Background: Neurons rely exclusively on mitochondrial oxidative phosphorylation to meet cellular energy demands, and disruption of mitochondrial function often precipitates neuronal cell death. Auditory neurons in the chick brain stem (n. magnocellularis [NM]) receive glutamatergic innervation exclusively from ipsilateral eighth nerve afferents.
