Behavioural effects of 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT) in monkeys.


PMID 2139614

Abstract

Subcutaneous injections of a 5-HT1A receptor agonist, 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT), in monkeys induced distinct behavioural changes characterized by head weaving, hindlimb extension and upper limb fluttering. The effects were dose-dependent and were similar to the 5-HT syndrome induced in rats by 8-OH-DPAT. The 5-HT receptor antagonist, metergoline, attenuated the behavioural syndrome seen in response to 8-OH-DPAT. These results suggest that 8-OH-DPAT induces a 5-HT1A receptor-mediated behavioural syndrome in monkeys as well as in rodents.
