[Biogenic amines in the ganglia of the autonomic nervous system in emotional stress].

Rabbits with different stability of cardiovascular functions were shown to have different activity of sympathetic nervous system under emotional stress. A small enhancement of the system activity occurred in animals with practically unchanged arterial pressure, whereas its hyperactivity was found in the animals with a progressive decrease of arterial pressure. Different changes of catecholamines in the nodose ganglia of these two groups of animals seem to reflect the participation of those ganglia in the maintenance of stable cardiovascular functions in extreme conditions.
