The study will last from four to six months and includes an initial screening period (three days/nights in the Sleep Laboratory) and three experimental periods. The entire study will require a total of 21 nights in the Sleep Laboratory. Each experimental period will last approximately one month and includes six days/nights in the Sleep Laboratory.


The study will include nights with limited sleep, blood draws and electroencephalography (EEG) tests to measure the brain's electrical activity, and testing to determine how thinking and performance are effected by decreased sleep.
