Gene variants of brain dopamine pathways and smoking-induced dopamine release in the ventral caudate/nucleus accumbens.
CONTEXT Preclinical studies demonstrate that nicotine administration leads to dopamine release in the ventral striatum. However, human studies reveal considerable interindividual variability in the extent of smoking-induced dopamine release. OBJECTIVE To determine whether common gene variants of the brain dopamine pathway explain this observed phenotypic variability in humans. DESIGN Blood ...
متن کاملDistinct presynaptic control of dopamine release in striosomal and matrix areas of the cat caudate nucleus.
By use of a sensitive in vitro microsuperfusion method, the cholinergic prsynaptic control of dopamine release was investigated in a prominent striosome (areas poor in acetylcholinesterase activity) located within the core of cat caudate nucleus and also in adjacent matrix area. The spontaneous release of [3H]dopamine continuously synthesized from [3H]tyrosine in the matrix area was found to be...
متن کاملRepetitive transcranial magnetic stimulation of the human prefrontal cortex induces dopamine release in the caudate nucleus.
Dopamine is implicated in movement, learning, and motivation, and in illnesses such as Parkinson's disease, schizophrenia, and drug addiction. Little is known about the control of dopamine release in humans, but research in experimental animals suggests that the prefrontal cortex plays an important role in regulating the release of dopamine in subcortical structures. Here we used [(11)C]raclopr...
متن کاملEffect of cholecystokinin-octapeptide on dopamine release from slices of cat caudate nucleus.
The cat caudate nucleus has been reported to possess a rich and fairly even distribution of nerve endings, containing both dopamine- and cholecystokinin-like peptides. In this study, the effect of cholecystokinin-octapeptide (CCK-8) on basal and electrically evoked tritium outflow from slices of cat caudate nucleus previously labeled with [3H]dopamine was examined. Evoked tritium outflow from s...
متن کاملContinuous determination of 3H-labelled 3,4-dihydroxyphenethylamine (dopamine) synthesis and release in the cat caudate nucleus in vivo.
Three major approaches have been classically used to study the release of dopamine (3,4dihydroxyphenethylamine) from dopaminergic terminals of the nigrostriatal pathway in the cat. The amine has been determined in perfusates (1) from the lateral ventricle (Portig & Vogt, 1969; Von Voigtlander & Moore, 1971), (2) from push-pull cannulae introduced into the head of the caudate nucleus (McLennan, ...
