Dopaminergic regulation of limbic-striatal interplay: 2006 CCNP Young Investigator Award.(Canadian College of Neuropsychopharmacology)
November 1, 2007... Neurochemical, electrophysiological and behavioural evidence indicates that certain forms of goal-directed behaviours are mediated by complex and reciprocal interactions between limbic and dopamine (DA) inputs in the nucleus accumbens (NAc)....

Association of [alpha]4[beta]2 nicotinic receptor and heavy smoking in schizophrenia.(Research Article/Article de recherche)

Amygdala reactivity to masked negative faces is associated with automatic judgmental bias in major depression: a 3 T fMRI study.(Research Paper/Article de recherche)(functional magnetic resonance imaging at 3 T)
November 1, 2007... Objective: In a previous study, we demonstrated that amygdala reactivity to masked negative facial emotions predicts negative judgmental bias in healthy subjects. In the present study, we extended the paradigm to a sample of 35 inpatients...

In vivo measurements of brain trapping of [sup.11]C-labelled [alpha]-methyl-L-tryptophan during acute changes in mood states.(Brief Report/Rapport sommaire)
November 1, 2007... Background: Little is known about the specific contribution of serotonin (5-HT) to the neurobiology of emotion and mood in healthy people. In an exploratory study, we sought to investigate the effect of rapid and sustained changes of emotional...

Malondialdehyde levels in adult attention-deficit hyperactivity disorder.(Brief Report/Rapport sommaire)(Clinical report)
November 1, 2007... Objective: To evaluate the biochemical basis of adult attention-deficit hyperactivity disorder (A-ADHD), we compared lipid peroxidation status in the plasma of A-ADHD patients, and that of control subjects without A-ADHD by quantifying the...
