Inhibition of endotoxin-induced temperature change by behavioral conditioning using alpha-melanocyte-stimulating hormone as an unconditioned stimulus.

abstract：:Nonmammalian peptides of the tachykinin, bombesin and opioid families, injected into the brain ventricles, potently and specifically affect drinking behaviour of rats and pigeons. These peptides, or at least their counterparts, have been found in the brain of mammals and birds. It has been hypothesized that these endo...
