Homepage PRINCIPLE: Cytochrome oxidase is the collective name for part of the oxidative respiratory chain of enzymes located exclusively in the mitochondria of cells. A simple histochemical staining for the metabolic enzyme cytochrome oxidase (CO) (Wong-Riley, 1979) produces a regular pattern of darkly stained patches in the supragranular layers of the visual cortex (Horton and Hubel, 1981; Carroll and Wong-Riley, 1984; Horton, 1984; Horton and Hedley-Whyte, 1984; Murphy et al., 1990, 1991a, b, 1995). In V1, cytochrome oxidase histochemistry has revealed a regular array of darkly staining … The appearance of cytochrome oxidase immuno- staining within neurons in brain was similar to that described in DRG; the staining had a granular ap- pearance and was localized in somal cytoplasm. Ever since Wong–Riley first reported in the late 1970s that histological staining using the chemical reactions of cytochrome oxidase (CO), a metabolic enzyme in the mitochondria, is useful to reveal the cytoarchitecture of the brain (Wong-Riley, 1979), the CO histochemistry method has been widely used in the field of neuroanatomy, especially in carnivores and primates. Cytochrome c oxidase (COX), or complex IV of the mitochondrial respiratory chain, catalyses the transfer of electrons from reduced cytochrome c to molecular oxygen, and couples this reaction to proton pumping across the inner mitochondrial membrane. Cytochrome oxidase staining was used as a marker of metabolic activity in neural elements in the rat major pelvic ganglion.
