Abstract The original Human Connectome Project yielded a rich data set on structural and
functional connectivity in a large sample of healthy young adults using improved methods of …

Cerebral blood flow (CBF) and cerebral metabolic rate are normally coupled, that is an
increase in metabolic demand will lead to an increase in flow. However, during functional …

Why does performing certain tasks cause the aversive experience of mental effort and
concomitant deterioration in task performance? One explanation posits a physical resource …

Human brain functional networks contain a few densely connected hubs that play a vital role
in transferring information across regions during resting and task states. However, the …

When someone asks,“How do you feel?”, your answer includes your bodily feelings as well
as your emotional feelings. Influential models of emotion view the embodiment of emotions …

Cognitive fatigue and boredom are two phenomenological states that reflect overt task
disengagement. In this article, we present a rational analysis of the temporal structure of …

Objective: We compared the ability of arterial spin labeling (ASL), an MRI method that
measures cerebral blood flow (CBF), to that of FDG-PET in distinguishing patients with …

To date, functional 1H NMR spectroscopy has been utilized to report the time courses of few
metabolites, primarily lactate. Benefiting from the sensitivity offered by ultra-high magnetic …

Resting-state functional magnetic resonance imaging (fMRI), a promising technique for
measuring brain activities during rest, has attracted much attention in the past few years. In …

Brain metabolism increases during stimulation, but this increase does not affect all energy
metabolism equally. Briefly after stimulation, there is a local increase in cerebral blood flow …
