[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.
