Kappa Opioid-Oxytocin Interactions During Long-Term Partner Separation: Insights from PET Imaging in Titi Monkeys (Plecturocebus cupreus)

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.

Brain Kappa Opioid Receptor Availability Across Stress and Social Buffering Conditions: A Positron Emission Tomography Study in Coppery Titi Monkeys

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.

Mapping Kappa Opioid Receptor Binding in Titi Monkeys with 11C-GR103545 PET

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.

Schema support for forming inferences in the human brain

This study investigates how memory schemas facilitate associative inference in the brain using fMRI, finding that schema congruency enhances integration of associations, and sleep, but not reward, supports this process.
