Abstract
Changes in the rate and character of energy metabolism in the mitochondria, of the visual system of the brain induced by prolonged visual deprivation (from birth until the age of 2.5 months) were shown to be reversible. The degree of normalization differed for mitochondria of the visual cortex and superior colliculus. During the 2-week recovery period (when the animal was transferred to ordinary conditions of illumination) the rate of these processes increased, when glutamic acid was used as the substrate, and reached the control level or exceeded it somewhat. The rate of electron transport in the cytochrome c-cytochrome oxidase section of the succinate oxidase oxidation chain, which was increased during deprivation, diminished in the recovery period and came close to the control level The role of specific impulse activity in the formation of mitochondrial energy processes in the brain with age is discussed.
