...Gianna Spitta; Maria Garbusow; Ralph Buchert; Andreas Heinz Background: Alcohol-associated alterations of the dopaminergic (DA) system have been investigated via functional molecular imaging methods such as single-photon emission tomography (SPECT) and positron emission tomography (PET) over many...

... availability via 18 F-fallypride positron emission tomography applying a region of interest (ROI) approach. We selected ROIs for the prefrontal cortex (PFC) and the anterior cingulate cortex (ACC). Our sample included 19 healthy controls (low risk [LR]), 19 individuals at high risk (HR) to develop addiction...

...Martin A. Weiler; Monte S. Buchsbaum; Christian Gillin; Richard Tafalla; William E. Bunney, Jr. This study explored the relationship between rapid eye movement (REM) sleep and schizophrenia using positron emission tomography. Glucose use was compared between 49 schizophrenics, 30 awake controls...

...Hans Herzog; Vikram R. Lele; Torsten Kuwert; Karl-Josef Langen; E. Rota Kops; Ludwig E. Feinendegen Using positron emission tomography (PET), measurements of the regional cerebral metabolic rate of glucose (rCMRGlc) are able to delineate cerebral metabolic responses to external or mental...

...Mark Katz; Monte S. Buchsbaum; Benjamin V. Siegel, Jr.; Joseph Wu; Richard J. Haier; William E. Bunney, Jr. We studied 18 never-medicated schizophrenic patients and 22 normal control subjects with 18 F-deoxyglucose (FDG) positron emission tomography. Patients and controls performed the continuous...
