Trial Summary
Trial Overview
Inclusion Criteria
This project hypothesizes that the brain's opioid system determines rejection sensitivity, a
personality trait that is a vulnerability factor and feature of several psychiatric
disorders. This project will use positron emission tomography to measure the brain's opioid
response to social rejection and acceptance in a nonclinical population with varying levels
of rejection sensitivity. The results will provide the first major step towards understanding
a neurotransmitter mechanism for rejection sensitivity, allowing for further investigation
into predicting and treating its associated disorders.
