This study uses PET imaging in titi monkeys to examine KOR availability and plasma OT changes during partner separation, finding reduced KOR in nucleus accumbens and sex-dependent OT responses.

This study uses PET to measure kappa opioid receptor availability in coppery titi monkeys under different stress and social conditions, showing condition-dependent binding changes in brain regions like the amygdala and hippocampus.

This study uses 11C-GR103545 PET to assess KOR binding in titi monkeys, showing significant reduction in BPND with a KOR antagonist but not with a KOR agonist.
