A Visual ERP Study of Impulse Inhibition following a Zaleplon-Induced Nap after Sleep Deprivation

The side effects of a zaleplon-induced nap as a countermeasure in the reduction of impulse inhibition function decline following 30 h of sleep deprivation (SD) were examined by event-related brain potentials. Sixteen adult participants performed a Go/NoGo task at five time points: (1) baseline; (2) after 30 h of SD; (3) upon sudden awakening, also called 2 h post-drug; (4) 4 h post-drug; and (5...

Ageing, physical function, and the diurnal rhythms of cortisol and dehydroepiandrosterone.
