[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. The spatial reorganization of the organellas in the neuron demonstrates that some new integrations take place in its metabolic system and reflects its another qualitative state. This serves as an impulse for structural adaptive modifications of the synaptic apparatus. There is a reason to suppose that one of the ways for organization of the alive system stability to an emotional stress is the way of reorganization of the connections, creation of another physiological architecture of the functional system, that can ensure the adaptive reactions of the organism to emotional overstrains.
