[The morphochemical characteristics of the brain in Wistar rats that differ by open-field motor activity].

[Article in Russian]


By cytochemical and biochemical methods it is established that in rats with low motor activity the increased content of proteins of cytoplasma and nuclei of neurones of the sensorimotor cortex, caudate nucleus and n. accumbens, the increased activity of a number enzymes of oxidizing and protein metabolism in them are combined with a low activity of enzymes of mediator exchange. In the studied formations in rats with high motor activity an increased activity of synaptic and membrane forms of acetylcholinesterase appears at the same level of activity of cholineacetyltransferase in these subcortical formations and at high monoamineoxidase activity in cellular structures of the cortex and in subcortical formations. It is shown that in animals of the same line but differing by the behaviour in the open field, brain formations such as the sensorimotor cortex, caudate nucleus and n. accumbens have their own biochemical properties of the studied characteristics.
