Recent Research Projects

PI: Todd Korthuis, MD, MPH
MARC Pilot Project (Methamphetamine Abuse Research Center)
Title: Risky Decision Making in Methamphetamine Users:
The Role of Opioid Blockade The primary goal of this MARC pilot proposal is to probe the neural mechanism of the effect of endogenous opioid blockade on impulsive choice in HIV-infected methamphetamine (MA) users. The proposal extends the scope of a recently funded NIDA award (R21DA033182) assessing neural mechanisms of endogenous opioid blockade on impulsive choice in non-HIV-infected MA users, to include HIV-infected subjects.
