Tail temperature in rats after intraventricular injections of 6-hydroxydopamine or 5,7-dihydroxytryptamine.
The tail vasomotor tone in rats is reduced by the intraventricular injection of 5,7-dihydroxytryptamine but not by 6-hydroxydopamine. Central serotonergic but not noradrenergic neurons participate in vasoconstriction of the tail.
