In the past two decades brain connectomics has evolved into a major concept in
neuroscience. However, the current perspective on brain connectivity and how it underpins …

Cognition and behavior are emergent properties of brain systems that seek to maximize
complex and adaptive behaviors while minimizing energy utilization. Different species …

The dopaminergic system is a central component of the brain's neurobiological framework,
governing motor control and reward responses and playing an essential role in various …

External tasks evoke characteristic fMRI BOLD signal deactivations in the default mode
network (DMN). However, for the corresponding metabolic glucose demands both …

The finding of reduced functional MRI (fMRI) activity in the default mode network (DMN)
during externally focused cognitive control has been highly influential to our understanding …

Impaired glucose metabolism in the brain has been linked to several neurological disorders.
Positron emission tomography and carbon-13 magnetic resonance spectroscopic imaging …

Purpose Positron emission tomography (PET) provides precise molecular information on
physiological processes, but its low temporal resolution is a major obstacle. Consequently …

The nervous and circulatory system interconnects the various organs of the human body,
building hierarchically organized subsystems, enabling fine-tuned, metabolically expensive …

The ability to solve cognitive tasks depends upon adaptive changes in the organization of
whole-brain functional networks. However, the link between task-induced network …

Abstract Serotonin (5-HT) plays an essential role in reward processing, however, the
possibilities to investigate 5-HT action in humans during emotional stimulation are …
