Title Executive functions and the ability to sustain vigilance during sleep loss
Bibliographic information Feb. 2009, Vol.80, No.2, p.81-87. Illus. 62 ref.
Abstract It has been suggested that individuals with higher activation of the prefrontal cortex may be less vulnerable to fatigue. This hypothesis was tested in a sample of 54 healthy volunteers who were assessed bi-hourly for psychomotor vigilance during 41h of sleep deprivation. Subsets of these subjects, representing the top and bottom quartiles based on their vigilance performance were compared with respect to baseline neuro-cognitive abilities. The sleep deprivation resistant group scored significantly higher than the sleep deprivation vulnerable group on all three baseline tasks assessing prefrontal neuro-cognitive abilities. Other findings are discussed.
