PSYC23H3 Lecture Notes - Lecture 4: Prairie Vole, Montane Vole, Oxytocin Receptor
Document Summary
Monogamy and the prairie vole (carter and getz) Prairie voles form long lasting pair bonds and both aprents share in raising their young. Oxytocin and vasopressin are important and have roles in reproduction and body water regulation. The chief criterion that defines monogamy is a life long association between a male and a female. Females and males of monogamous species are the same size, defend the net and territory, both care for young, form complex social groups as well including extending fam and offspring of various ages. Monomogy is rare in mammals and commn in birds. Sexual exclusivity is not part of monogamy= proof from dna fingerprinting. Pheromones used= avtivate and trigger hormonal events needed to activate the ovaries and to insuce heat vomeronasal organ regulates and mediates the effects of pheromones, as does the olfac bulb. Once female is exposed to male odors, levels of ne, and lhrh change and lhrh causes pituitary gland to relase.
