Visuospatial navigation in animals and human subjects is generally studied using maze
exploration. We used functional MRI to observe brain activation in male and female subjects as …

BACKGROUND: Dysfunctional reward processing, accompanied by a limited ability to
tolerate reward delays, has been proposed as an important feature in attention-deficit/…

Flow refers to a positive, activity-associated, subjective experience under conditions of a
perceived fit between skills and task demands. Using functional magnetic resonance perfusion …

We describe a principal component analysis (PCA) method for functional magnetic resonance
imaging (fMRI) data based on functional data analysis, an advanced nonparametric …

Objective Animal studies assessing mechanisms of self-starvation under conditions of stress
and diet suggest a pivotal role for the mesolimbic reward system in the maintenance of core …

Previous studies on working memory (WM) function in adults with attention‐deficit/hyperactivity
disorder (ADHD) suggested aberrant activation of the prefrontal cortex and the …

Background: Aerobic endurance exercise has been shown to improve higher cognitive
functions such as executive control in healthy subjects. We tested the hypothesis that a 30-minute …

All known human societies establish social order by punishing violators of social norms.
However, little is known about how the brain processes the punishment threat associated with …

Previously, experimentally induced flow experiences have been demonstrated with perfusion
imaging during activation blocks of 3 min length to accommodate with the putatively slowly …

Electrophysiological correlates of impulsiveness were investigated in thirty-two healthy
subjects using event-related potentials (ERP). Impulsiveness was determined by calculating …
