[The role of catecholamines in various brain nuclei in maintaining the stability of physiological functions in emotional stress].
Direct arterial BP recording through an indwelling catheter in the tail artery showed August rats to be more prone to disorders of arterial BP control under emotional stress, as compared to Wistar rats. High baselines of catecholamines, dopamine in particular, in the cerebral nuclei, and the involvement of zone A1 adrenalin BP control are unfavorable indicators of a predisposition to abrupt BP changes in response to stress. Locus ceruleus is shown to play an essential role in BP control under emotional stress, its functions being largely determined by genetic mechanisms.
