There is not much information on a possible locus in the brain at which opioids exert their effects on social behavior. In an effort to address this issue we analyzed regional opioidergic activity upon social isolation-induced social...
An in vivo autoradiographic procedure was employed to visualize local changes in brain opioid receptor occupancy in juvenile rats. This procedure is based on the assumption that released endogenous ligand will exclude exogenously applied tracer, in this case [ 3 H]diprenorphine, from opioid receptors. Increases in availability of opioid peptides will then result in decreased opioid receptor...
