The visual system of adult zebra finches was investigated immunocytochemically for the distribution of the Ca super(2+) -binding protein parvalbumin for the activity of the respiratory enzyme cytochrome oxidase, and for the uptake of 2-deoxyglucose. In the visual system, only nuclei of the tecto-fugal pathway and related nuclei were labeled by the parvalbumin antiserum. With few exceptions there was a striking correlation of parvalbumin-positive and cytochrome oxidase-positive nuclei of the visual system. Parvalbumin concentrations suggest as one possibility that special Ca super(2+) mechanisms are present in neuronal systems that can reach high levels of electrical activity.
