文摘

Dominant male starlings had lower OPRK1 mRNA in VTA and mPOA than subordinates. OPRK1 in VTA related negatively to sexual/agonistic behaviors and gonad volume. PDYN in mPOA related negatively to nesting behaviors and positively to gonad volume. Area X PDYN related positively to singing; OPRK1 related positively to gonad volume. Kappa receptors/dynorphin relate to individual differences in sociosexual behaviors.
