Brain dopamine (DA) has long been implicated in cognitive control processes, including
working memory. However, the precise role of DA in cognition is not well-understood, partly …

It is well recognised that patients with Parkinson's disease exhibit cognitive deficits, even in
the earliest disease stages. Whereas, l-DOPA therapy in early Parkinson's disease is …

Converging evidence from human lesion, animal lesion, and human functional neuroimaging
studies implicates overlapping neural circuitry in ventral prefrontal cortex in decision-…

We investigated how dopamine (DA) systems contribute to cognitive performance in the
domain of learning and attentional flexibility by examining effects of withdrawing DA-ergic …

Event-related functional magnetic resonance imaging was used to measure blood oxygenation
level-dependent responses in 13 young healthy human volunteers during performance …

In the current study we investigated the role of dopamine in attentional and socio-emotional
functioning by examining effects of withdrawing dopaminergic medication in patients with …

5-Hydroxytryptamine (5-HT, serotonin) has long been implicated in a wide variety of emotional,
cognitive and behavioural control processes. However, its precise contribution is still not …

Recent years have seen a rejuvenation of interest in studies of motivation–cognition interactions
arising from many different areas of psychology and neuroscience. The present issue of …

… Cools AR. Role of the neostriatal dopaminergic activity in sequencing and selecting
behavioural strategies: facilitation of processes involved in selecting the best strategy in a stressful …

This study examined the effects of l‐dopa medication in patients with Parkinson’s disease on
cortical and subcortical blood flow changes during two tasks known to involve frontostriatal …
