The effects on thermoregulation of intracerebroventricular injections of L-aspartic acid in the sheep.

L-Aspartic acid was injected into a lateral cerebral ventricle of the sheep at ambient temperatures between 0 degrees and 40 degrees C. Doses of 100 or 500 nmoles-kg-1 caused a rise in heat production and/or a decrease in heat loss; rectal temperature rose. Atropine sulphate attenuated or prevented these effects.
