Hyperphagia in cold-adapted rats: a possible role for neuropeptide Y.
The feeding response to intracerebroventricular injection of neuropeptide Y or to starvation is greater in cold-adapted than in non-adapted rats, suggesting that with cold-adaptation the central sensitivity to this peptide is increased. Hypometabolism and hypothermia (which usually follow the administration of neuropeptide Y) cannot, however, be demonstrated in the course of cold-adaptation per se.
