FEATURES OF STRUCTURAL AND FUNCTIONAL CORRELATORS OF HOMEOSTATIC STABILITY FUNCTIONS OF THE RATS SENSORIMOTOR CEREBRAL CORTEX

Authors have studied the behaviour of neuronal pool of sensorimotor cerebral cortex of 124 rats (white, not thoroughbred males) in usual conditions of vivarium and under effect of external disturbances and changes of internal medium of organism.

It has established, that neuronal pool forms the functional system, which represent the definite correlation of cells witch structural manifestation of different functional activity. In usual conditions this correlation some change according to season or a day of month. The correlation of neurons deviates to increase of the cells subpopulation with expressed reparation activity and exhaustion activation under external disturbances. In case of changes of internal medium of the organism, there are increase in subpopulation of the cells with sings of wasted activity and decrease in the number of the cells with signs of intensified regeneration. Authors comes to the conclusion that neuronal pool as changing its organization is preserving the optimum standard of activity as functional system, at the same time is intensifing its regenerative possibilities that gives an opportunity for a long-term functioning.
