Vitamin B12 enhances the phase-response of circadian melatonin rhythm to a single bright light exposure in humans.

abstract：:Acute physical exercise (APE) induces an increase in the individual alpha peak frequency (iAPF), a cortical parameter associated with neural information processing speed. The aim of this study was to further scrutinize the influence of different APE intensities on post-exercise iAPF as well as its time course after ex...
