title: [Rhythmic activity (25--35 Hz) of autonomic nerves and its physiologic role].
abstract: A study of daily ongoing activity of the sympathic and vagal nerves has shown that 14,6% of this activity are of a rhythmic form (25--35 c/s) arising synchronously in both nerves. Its formation is attended by an enhancement (by 50--100%) of the nerve tone. The appearance of the rhythmic activity bears a non-specific character. A spatial synchronization within the range of 25--35 c/s has been found between the rhythmic activity of the vegetative nerves and that of brain structures. It is suggested that the rhythmic activity of the vegetative nerves reflects a homeostatic mechanism, which is indicative of the appearance of alertness in the nervous system.
