Molecular-imaging studies of dopaminergic neurotransmission measure biomarkers of
dopamine (DA), such as the DA transporter and D1 and D2 receptor densities in the living …

Striatal dopamine (DA) is thought to code for learned associations between cues and
reinforcers and to mediate approach behavior toward a reward. Less is known about the …

Process-specific training can improve performance on untrained tasks, but the magnitude of
gain is variable and often there is no transfer at all. We demonstrate transfer to a 3-back test …

Recently, attempts have been made to alter the capacity of working memory (WMC) through
extensive practice on adaptive working memory tasks that adjust difficulty in response to …

Cell cycle checkpoints are signal transduction pathways activated after DNA damage to
protect genomic integrity. Dynamic spatiotemporal coordination is a vital, but poorly …

Hypertension affects more than 40% of adults worldwide and is associated with stroke,
myocardial infarction, heart failure, and other cardiovascular diseases. It has also been …

In our constantly changing environment, we are frequently faced with altered circumstances
requiring generation and monitoring of appropriate strategies, when novel plans of action …

The ability to dynamically use various aspects of cognition is essential to daily function, and
reliant on dopaminergic transmission in cortico-striatal circuitry. Our aim was to investigate …

This systematic review describes human molecular imaging studies which have investigated
alterations in extracellular DA levels during performance of behavioral tasks. Whilst …

The prefrontostriatal network is considered to play a key role in executive functions. Previous
neuroimaging studies have shown that executive processes tested with card‐sorting tasks …
