This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Our work demonstrates that oxytocin is released in the nucleus accumbens during pair bond formation in female prairie voles. Using retrograde labeling techniques we determined that the oxytocin released within the accumbens originates from oxytocinergic neurons within the paraventricular nucleus. We also developed an adeno-associated viral vector to over-express the oxytocin receptor in the prairie vole brain. Our work shows that increasing oxytocin receptor expression in the accumbens facilitates social attachments and that women who have suffered abuse or neglect in childhood have decreased oxytocin concentrations in the cerebrospinal fluid. Oxytocin has recently been shown to enhance social cognition in autism spectrum disorders. Our studies in prairie voles have important implications for the development of potential drug therapies for autism. This study seeks to understand the role of the neuropeptide oxytocin in the regulation of social behavior. The highly social and monogamous prairie vole is an excellent animal model for investigating the role of oxytocin.
