The brain neuronal systems defined by the neurotransmitter dopamine (DA) have since long
a recognized role in the regulation of motor functions. More recently, converging evidence …

It is generally considered that Parkinson's disease is induced by specific agents that
degenerate a clearly defined population of dopaminergic neurons. Data commented in this …

The default mode network (DMN) is a set of functionally connected brain regions which
shows deactivation (task-induced deactivation, TID) during a cognitive task. Evidence shows …

OBJECTIVE: There is growing interest in distinguishing the biological bases of sex
differences in behavior from environmental influences. Sex hormone levels seem to be …

Dopamine transporter imaging is a valuable tool to investigate the integrity of the
dopaminergic neurons. To date, several reports have shown an age-associated decline in …

We examined the relationship of age-related losses of striatal dopamine transporter (DAT)
density to age-related deficits in episodic memory and executive functioning in a group of …

Involvement of the dopaminergic system has been suggested in patients suffering from
attention deficit hyperactivity disorder (ADHD) since the symptoms can be successfully …

Substance abuse among older adults has received little attention in the past, presumably
because this population has traditionally accounted for only a small percentage of the drug …

Because age‐related changes in brain dopaminergic innervation are assumed to influence
human disorders involving dopamine (DA), we measured the levels of several presynpatic …

Parkinson's disease is a progressive neurodegenerative disorder characterized by a
selective loss of dopamine in the striatum. Problems remain in the accurate diagnosis of …
