The proposed project seeks to demonstrate the engagement of post-exposure dopamine
neurotransmission and downstream acute reorganization of dopaminergic resting-state neural
networks as a means of increasing consolidation of extinction memories formed during analogue
exposure therapy in adult women with PTSD. Participants will include 120 women aged 21-50
with a current diagnosis of PTSD related to physical or sexual assault, English speaking, and
medically healthy. Participants will complete the stages of the study across 2-3 days,
depending on participant need.
