[Subcellular changes in the cortex of the motor analyzer and hippocampus of dogs with locally manifested neuroses].

In experiments on dogs with local neurosis-continuous flexion of the foreleg-changes were revealed in the beta-rhythm amplitude and the frequency of mean unit activity in the motor cortex, and the appearance and increased amplitude of the theta-rhythm in the hippocampus. Specific activity of Na+-K+-activated, and Mg2+-dependent ATPase decreases in subcortical fractions of the experimental animals' cerebral cortex by 55.0% in the synaptic membranes and 2 to 2.

[Content of N-acetylneuraminic acid in water-soluble and membrane fractions of various fractions from rat brain cortex].

The content of N-acetylneuraminic acid (ANA) was measured in the water-soluble and membrane fractions of the visual, locomotory, auditory and sensomotory divisions of rat brain cortex as well as in glycoproteins and glycolipids of the membrane fraction. The content of ANA in the water-soluble fraction of the visual, locomotory, auditory and sensomotory analyzers of brain cortex was 0.55, 0.

[Distribution of 5'-nucleotidase activity in the subcellular fractions of rabbit brain cortex].

The specific activity of 5'-nucleotidase was measured in the fractions of myelin, synaptic membranes, heavy and light synaptosomes and purified mitochondria of brain cortex of intact rabbits. The enzyme specific activity in these fractions was practically the same and made up to 2.2, 2.
