WHY YOU’RE GAY: A NEW STUDY SHOWS WHY BOY RATS LIKE OTHER BOY RATS
PUBLISHEDSexual Preference In Rats Influenced By Oxytoc And Dopamenanka/ basis for homosexual behavr has equently—and often hotly—been bated. They have been able to show that ndned homosexual preference male rats n be duced by oxytoc and the psychoactive dg qupirole. This go agast other studi, one of which suggted that the size of the SDN n be related to sexual preference male sheep and that homosexual behavr might be related to differenc bra anatomy.
Lockg two men a room and feedg them oxytoc and qupirole isn't gog to turn them gay, but the study do suggt that is possible for apparently heterosexual male rats to velop a ndned homosexual social and sexual leang, given the right ndns. This review discs the effect of ndng on the velopment of heterosexual and homosexual partner preferenc ronts.
MAKG GAY RATS
Th, unrstandg the bas of partner preference formatn is necsary to unrstand an important part of social behavr animals and aim of this mancript is to discs the role of learng on the exprsn of heterosexual and homosexual partner preferenc ronts. Assortative matg is believed to mata homozygosy a stra and, thereby, keep stras om outbreedg posive characteristics. Th, polygamo male rats acquired a preferred partner by exposure to a simple Pavlovian ndng procre that lked a ntral olfactory stimul to sexual reward duced by on the fact that the postejaculatory perd is sufficiently rewardg to support the velopment of heterosexual partner preference male rats, we tted s effects on ndned homosexual partner preference.
One day after the last ndng trial, mal were tted for homosexual partner preference a chamber wh two stud mal as potential partners, one almond scented and one unscented. Contrary to our hypothis, both groups failed to velop a ndned homosexual preference for the CS+ male, ditg that the ‘cril perd’ duced by ejaculatn is sufficient to support heterosexual, but not homosexual ndng of partner preference putatively heterosexual mal. This might dite that exposure to a male durg the postejaculatory perd rulted ndned play partner preference but not homosexual preference.
For stance, a D1 agonist or D2 antagonist blocks the formatn of matg-duced pair bonds (Ggrich et al., 2000); but a D2 agonist will facilate the formatn of pair bonds if the treated vole habat for few hours wh a potential partner (Wang et al., 1999), siar to the preference that velops after on the fact that enhanced D2-type receptor activy facilat the formatn of heterosexual partner preference, we tted the effect of a D2 agonist, qupirole, on the formatn of ndned homosexual preference. Four days after the fal ndng trial, the rats were dg-ee and tted for homosexual partner preference a three-partment chamber. Acrdgly, is likely that NAc D2-type receptor activy also modulat the formatn of ndned homosexual partner preferenc male rats and that repeated habatn unr the pharmalogil effects of qupirole helped crystallize the preference for the male has been also scribed that the proportn of D1 and D2 receptors the bra is different between monogamo and polygamo ronts.
