[Metabolic activity of thalamic and telencephalic auditory centers in the pigeon].
Distribution of activity of the mitochondrial oxidative enzyme cytochrome oxidase C was studied in the thalamic (Ov) and telencephalic (field L) auditory centers in pigeons. The CO activity level has been shown to differ in the central (core) and peripheral (belt) subdivisions of these centers: the high CO activity in the former (nCe, L2) and the much lower or absent in the latter (Ovl, Ovm, SPO). Comparison of our data with those of various avian and reptile species confirms the concept of the common plan of rostral auditory centers in sauropsid amniotes by the principle of the center-periphery (core-belt), which is characteristic of the corresponding mammalian centers. The separation of the central and peripheral parts of these centers is better pronounced in birds than in reptiles.
