Thermoregulatory effects of intraventricular injection of noradrenaline in the mouse and the influence of ambient temperature

Abstract
1. At an ambient temperature of 20° C, intraventricular injection of noradrenaline in the mouse resulted in hypothermia accompanied by a fall in metabolic rate and by cutaneous vasodilatation. Subcutaneous injection of noradrenaline resulted in hyperthermia with raised metabolic rate and cutaneous vasodilatation.
