Sleep restriction and age effects on waking alpha EEG activity in adolescents.

With effects of time of day, age, and order accounted for, sustained vigilance measured as the log of the signal to noise ratio on the PVT showed a trend ( F 1,2233 = 3.41, p = .065) toward increasing with increasing O1 eyes closed alpha, but this relation was not significant ( F 1,1965 = 0.05, p = .82) once the effect of prior night’s sleep duration was accounted for ( Figure 7B ).
