Specificity-related suppression of responses to binary mixtures in olfactory receptors of the Colorado potato beetle.

abstract：:Mapping studies with central drug injections in the hungry rat have identified the perifornical lateral hypothalamus as being uniquely sensitive to the feeding suppressive effects of exogenous dopamine, as well as anorexic drugs which release endogenous catecholamines. In the present study, the hypothalamic dopamine-r...
