OBJECTIVE: Alcohol and other drugs of abuse stimulate dopamine release in the ventral
striatum, which includes the nucleus accumbens, a core region of the brain reward system, and …

Brain imaging with positron emission tomography has identified some of the principal cerebral
structures of a central network activated by pain. To discover whether the different cortical …

OBJECTIVE: In abstinent alcoholic patients, a low availability of dopamine D 2/3 receptors
in the ventral striatum and adjacent putamen was associated with a high level of craving for …

Fluorine-18 is among the most commonly used radionuclides for positron emission tomography
(PET).[1] This non-invasive imaging technique is capable of providing in vivo information …

Background: Purpose of this study was to investigate the functional relationship between
electroencephalographic (EEG) alpha power and cerebral glucose metabolism before and after …

To determine how opiate receptor distribution is co-localized with the distribution of nociceptive
areas in the human brain, eleven male healthy volunteers underwent one PET scan with …

Previous positron emission tomography (PET) studies with levodopa analogs have revealed
a modestly increased capacity for dopamine synthesis in the striatum of patients with …

Objective: Muscle pain differs from skin pain with respect to quality, accuracy of localization,
and unpleasantness. This study was conducted to identify the brain regions associated with …

Background The current study investigated dose-dependent effects of the mu-selective agonist
remifentanil on regional cerebral blood flow (rCBF) in volunteers using positron emission …

Purpose: Although animal data are suggestive, evidence for an alteration of the extrastriatal
dopaminergic system in human focal epilepsy is missing. Methods: To quantify D2/D3‐…
