What we do
This section conducts both functional and structural brain imaging studies related to alcoholism. For functional work we primarily use functional magnetic resonance imaging (fMRI) techniques although positron emission tomographic (PET) studies are also undertaken. Structural studies include both measurements of brain volumes using MRI as well as diffusion tensor imaging (DTI). We also use nuclear magnetic resonance (NMR) spectroscopy to measure various brain metabolites. Recently much of our functional work has focused on emotion and motivation as they related to substance abuse. Pharmacological fMRI studies are also employed, particularly studies involving alcohol administration.
