AB  - OBJECTIVE: The deleterious neurocognitive effects of laboratory-controlled
      short-term sleep deprivation are well-known. The present study investigated
      neurocognitive changes arising from chronic sleep restriction outside the
      laboratory. METHODS: Sleep patterns of 24 undergraduates were tracked via
      actigraphy across a 15-week semester. At the semester beginning, at a midpoint,
      and a week before finals, students performed the Psychomotor Vigilance Test (PVT)
      and cortical arousal was measured via event-related potentials (ERP) and resting 
      state electroencephalography (EEG). RESULTS: Average daily sleep decreased
      between Session 1 and Sessions 2 and 3. Calculated circadian rhythm measures
      indicated nighttime movement increased and sleep quality decreased from Sessions 
      1 and 2 to Session 3. Parallel to the sleep/activity measures, PVT reaction time 
      increased between Session 1 and Sessions 2 and 3 and resting state alpha EEG
      reactivity magnitude and PVT-evoked P3 ERP amplitude decreased between Session 1 
      and Sessions 2 and 3. Cross-sectional regressions showed PVT reaction time was
      negatively associated with average daily sleep, alpha reactivity, and P3 changes;
      sleep/circadian measures were associated with alpha reactivity and/or P3 changes.
      CONCLUSIONS: Small, but persistent sleep deficits reduced cortical arousal and
      impaired vigilant attention. SIGNIFICANCE: Chronic sleep restriction impacts
      neurocognition in a manner similar to laboratory controlled sleep deprivation.
