[Pharmacologic analysis of the cholinergic vasodilation in unanesthetized animals].
Cholinergic vasodilatation evoked by hypothalamic stimulation in cats could be elicited by stimulation of both the emotional and mator areas of the brain. Tranquilizers affected the cholinergic vasodilatation in different ways: reserpine decreased, catapresan increased, while diazepam had no effect on amplitude of the cholinergic vasodilatation. The latter seems to be closely connected with activity of skeletal muscles but not with emotional reactions. Alpha--adrenergic structures of the c. n. s. are the activating mechanism of the central integration of cholinergic vasodilatation.
