Pharmacological magnetic resonance imaging (phMRI) maps the neurovascular response to a pharmacological challenge and is increasingly used to assess neurotransmitter systems. Here we investigated the hemodynamic response to a dopaminergic (DAergic) challenge with dextroamphetamine (dAMPH) in humans using arterial spin labeling (ASL) based phMRI. Twelve(More)
D-amphetamine (dAMPH) and methylphenidate (MPH) are stimulants used in the treatment of Attention Deficit Hyperactivity Disorder (ADHD). Preclinical studies have shown that in healthy animals, dAMPH induces dopamine (DA) dysfunction, as evidenced for instance by loss of DA levels and its transporters. It has also been suggested that DA plays an important(More)
BACKGROUND Dopamine (DA) is involved in systems governing motor actions, motivational processes and cognitive functions. Preclinical studies have shown that even relatively low doses of d-amphetamine (dAMPH) (equivalent to doses used in clinical Practice) can lead to DA neurotoxicity in rodents and non-human primates (Ricaurte et al., 2005).
