[Correlations between vegetative parameters in experimental emotional stress].

Correlative interrelations of the values of arterial pressure, heart and respiration rates were studied in rats by cross-correlation analysis, in conditions of free behaviour during acute immobilization stress and after chronic emotional two-month immobilization stress. During the acute emotional stress a disintegration of vegetative parametres is seen, the rate of it depends on the type of hemodynamic reaction to stress. The absence of such disintegration during immobilization of the animals enduring chronic stress, may point to the adaptation of these animals to repeated stress. The results obtained allow to suggest that the dissociation of the vegetative functions is a typical component of emotional stress reaction.
