Human cognitive function and its neural basis; neuroimaging
Current research explores the neural basis of the cognitive abnormalities that characterize schizophrenia, and the cognitive and blood flow changes caused by marijuana. Both areas of research involve both behavioral cognitive assessments and structural and functional neuroimaging. We have ongoing positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) studies of schizophrenic individuals, as well normal volunteers and occasional and chronic users of marijuana.
