[The intercellular connection of axons-capillaries in the light of genetically determined resistance to emotional stress].

Genetic factor is one of the main factors of systemic organization of animal resistance to emotional stress. This notion served as a basis for comparing ultrastructural specific of connections between nervous and vascular systems in catecholamine-synthesizing areas of different lines of Wistar and August rats. Quantitative difference has been observed in the structure of cell junctions.

[The mechanisms of the reorganization of functional systems in the ontogeny of rats].

Functional systems as well as other mechanisms of regulation of animal behavior (reflexes) have very high adaptive properties. Specific mechanisms of reorganization of the functional systems have been elaborated during ontogenesis to adapt an individual to changing environment.

[Spatial reorganization of the organelles of catecholamine-synthesizing group A1 neurons during emotional stress].

Dynamics of spatial reorganization of organellas in catecholamine-synthesizing neurons of A1 group, that participate in reactions of the cardiovascular control, have been studied under normal conditions and under stimulation of the ventromedial nucleus in the hypothalamus. During transition of the hypertensive reaction into the hypotensive one, concentration of various organellas in the Golgi complex area and in the perinuclear zone is intensively increasing. Deep mutual nucleocytoplasmic invaginations appear.
