in order to better delineate the profile of central actions of neuropeptide y (npy), the effects of intracerebroventricular administration of several doses (2.5-20 micrograms) of the peptide on spontaneous activity, muscular tone, body temperature, food intake, nociception and cataleptic manifestations were examined in rats. |

the most salient difference was that deletion of the n-terminal residue tyr1 of npy resulted in a five-fold loss in the potency for decreasing rectal temperature, whereas npy2-36 was relatively more potent than the native peptide to increase food intake in animals. |

since rats were deprived of food during the behavioural test, it is concluded that inhibition of sexual behaviour is a 'true', direct behavioural effect of npy, not due to a shift towards increased feeding. |
