[Morpho-chemical characteristics of the brain of rats genetically predisposed to catalepsy].
Cell organization of the cerebral cortex and striatum has been studied by+light optics and enzymatic activity of neuromediators catabolism--histochemically. In layers III and V of the sensomotor cortex and in the nucleus caudatus the number of neurons per unit area is increased, and their size is decreased. Volume of cytoplasm and nuclei of neurons in both layers is decreased, the latter--to less extent. The total amount of the perineuronal glia in the nucleus caudatus is also decreased at the expense of astroglia. In the cerebral cortex it is equal, but the ratio between astro-++- and oligodendroglia is changed. Acetylcholinesterase activity in the layers III and V of the sensomotor cortex is lower than in the control, while monoamine oxidase activity is kept at the control level. The genetically determined anomalies++ of growth and development of the cerebral cells is supposed to be considered as a structural base of the cataleptic state.
