    J Sleep Res 12:1-12. 2003
    ..These adaptive changes are hypothesized to restrict brain operational capacity and to persist for several days after normal sleep duration is restored, delaying recovery...

    Cynthia M LaJambe
    Department of Behavioral Biology, Division of Neurosciences, Walter Reed Army Institute of Research, Silver Spring, MD, USA
    Aviat Space Environ Med 76:108-13. 2005
    ..Caffeine is widely used to reverse alertness and performance decrements. However, caffeine's effects on subsequent recovery sleep and post-recovery performance are not well documented and, therefore, were evaluated...

    Nancy Jo Wesensten
    Department of Behavioral Biology, Division of Psychiatry and Neuroscience, Walter Reed Army Institute of Research, Silver Spring, MD 20910 7500, USA
    Sleep 28:93-103. 2005
    ..At effective doses, zolpidem induces sleep but also impairs performance. Combining melatonin with low-dose zolpidem may promote daytime sleep without exacerbating performance impairments seen with high-dose zolpidem alone...
