Journal ArticleDOI
Patterns of performance degradation and restoration during sleep restriction and subsequent recovery: a sleep dose-response study
Gregory Belenky,Nancy J. Wesensten,David R. Thorne,Maria L. Thomas,Helen C. Sing,Daniel P. Redmond,Michael B. Russo,Thomas J. Balkin +7 more
TL;DR: The results suggest that the brain adapts to chronic sleep restriction and in mild to moderate sleep restriction this adaptation is sufficient to stabilize performance, although at a reduced level.
Regional cerebral blood flow throughout the sleep- wake cycle
Allen R. Braun,Thomas J. Balkin,Nancy J. Wesensten,Richard E. Carson,M. Varga,Paul Baldwin,S. Selbie,Gregory Belenky,Peter Herscovitch +8 more
Journal ArticleDOI
Impaired decision making following 49 h of sleep deprivation.
TL;DR: The findings suggest that cognitive functions known to be mediated by the ventromedial prefrontal cortex, including decision making under conditions of uncertainty, may be particularly vulnerable to sleep loss and that this vulnerability may become more pronounced with increased age.
Journal ArticleDOI
Dissociated pattern of activity in visual cortices and their projections during human rapid eye movement sleep.
Allen R. Braun,Thomas J. Balkin,Thomas J. Balkin,Nancy J. Wesensten,Nancy J. Wesensten,Fuad G. Gwadry,Fuad G. Gwadry,Richard E. Carson,Richard E. Carson,M. Varga,M. Varga,Paul Baldwin,Paul Baldwin,Gregory Belenky,Gregory Belenky,Peter Herscovitch,Peter Herscovitch +16 more
TL;DR: A model for brain mechanisms subserving REM sleep where visual association cortices and their paralimbic projections may operate as a closed system dissociated from the regions at either end of the visual hierarchy that mediate interactions with the external world is suggested.
Journal ArticleDOI
Performance and alertness effects of caffeine, dextroamphetamine, and modafinil during sleep deprivation
TL;DR: At the doses tested, caffeine, dextroamphetamine, and modafinil are equally effective for approximately 2–4 h in restoring simple psychomotor performance and objective alertness.
