Data collection times for the first subject on an experimental night. During a 1-hr period, PVT and KSS data were collected twice during the first 45 minutes. In the last 15 minutes, EEG, saliva and a third PVT and KSS measures were collected. Four subjects were run each experimental night; start times for subsequent subjects were staggered by 15 minutes.
