title: [Features of metabolism in subcellular fractions of the motor cortex during restoration of visual nerve impulses].
abstract: Experimental data are obtained on cytochromoxidase (CO), acetylcholinesterase (AchE), MAO and ATPase activities in subfractions of synaptosomes and cellular mitochondria from the rabbit motor cortex following long-term visual deprivation. The first stage is characterized by elevated protein content and activation of enzymatic systems except K+; Na+--ATPase and CO. The tendency towards normalizing of protein content and activity of enzymes, particularly AchE and MAO occurred within 4 weeks. These data show that changes of enzymatic activity in subcellular components of the motor cortex following the sensory deprivation, are reversible but the process of neuronal recompensation in the integrative--starting system is complex and demands a longer time than in visual one.
