| Popis: | The levels of biogenic amines and of a number of the products of their metabolism were studied in the hypothalamic nuclei in Wistar and August rats, which have different levels of resistance to emotional stress; levels were also studied in structures functionally and anatomically associated with the hypothalamic nuclei, i.e., the reticular formation of the midbrain, the amygdaloid body, the septum, the locus ceruleus, the dorsal cervical nucleus, and the ventral region of the tegmentum. The genotype was found to determine the level of metabolism of biogenic amines in structures of the central nervous system in conditions of emotional stress. In August rats, the activities of the dopaminergic and serotoninergic systems, which are stress-limiting, decreased to a greater extent during 24-hour immobilization stress. Adrenaline levels in structures of the central nervous system in August rats were higher during stress. Changes in the contents of biogenic amines in the paraventricular and ventromedial nuclei of the hypothalamus in Wistar and August rats could affect the preganglionic neurons of the autonomic nervous system. |
