About
To assess the changes in brain activation and cerebral blood flow due to mental fatigue in a placebo-controlled study. More specifically we want to assess whether brain activation [measured with Blood Oxygen Level Dependent (BOLD) functional resonance imaging (fMRI)] is decreased during a Flanker task in a mentally fatigued state and whether this coincides with a decline in cognitive performance. In addition we also want to evaluate whether cerebral blood flow [measured with arterial spin labeled (ASL) fMRI] in a resting state is reduced when mentally fatigued.
