TL;DR: The posterior and downward displacement of the mean metabolic centroid is consistent with the concepts of hypofrontality, hyperactivity of subcortical structures, and neuroleptic effect in schizophrenics.

TL;DR: It is demonstrated that incorporation of computer science principles into functional neuroimaging clinical studies, facilitates deduction about the behavioral probes from the brain activation data, thus providing a valid tool that incorporates objective brain imaging data into clinical classification of psychopathologies and identification of genetic vulnerabilities.

TL;DR: Although still very preliminary, these studies exemplify how metabolic brain measurements can address questions of relevance in the investigation of drugs of addiction such as mechanisms of toxicity, addiction, withdrawal, and reinforcement of other drugs of abuse.

TL;DR: Positron emission tomography data has been used to investigate possible mechanisms for some of alcohol 3s effects and to provide additional evidence for the heritability of alcoholism.

TL;DR: In this article, the authors investigated the role of dopaminergic signaling in response inhibition in early stage Parkinson's disease and found that the PD group showed weaker striatal activations to salient events (infrequent vs. frequent events: stop vs. go trials).
