Muscular Nonshivering Thermogenesis in Cold-Acclimated Ducklings
In small terrestrial mammals, the existence of nonshivering thermogenesis (NST) is fully demonstrated in new-borns, cold-acclimated and hibernating species. The activation of the sympathetic catecholaminergic system by cold or by diet is largely documented. Norepinephrine is considered as the mediator of NST and brown adipose tissue as the major site of this NST.
