[Biochemical characteristics of the synaptosomes and mitochondria of the motor area of the cerebral cortex following switching off of sensory impulsation].

Changes in the specific activity of cytochrome oxidase, monoamine oxidase, acetylcholinesterase and Na,K-ATPase in the light and heavy synaptosomes and mitochondria of neurone bodies fractions in the motor cerebral cortex of rabbits were demonstrated under conditions of light (visual) deprivation. These changes were specific of different metabolic cycles and differed in individual cell ultrastructures. The influence of sensory impulsation on functional neuron activity in different projection regions of the cerebral cortex is discussed.
