TL;DR: The hypothesis that age-related changes in sleep are due to weaker circadian regulation of sleep and wakefulness is favored and manipulations of the circadian timing system, rather than the sleep homeostat, may offer a potential strategy to alleviate age‐related decrements in sleep and daytime alertness levels.

TL;DR: The results indicate that, like during nocturnal sleep, daytime sleep EEG oscillations including spindle activity are modified after declarative learning of word pairs, and demonstrate here that the nature of the learning material is a determinant factor for sleep-related alterations after declARative learning.

TL;DR: The gender effect is interpreted as a different strategy in women when performing the PVT, although the instructions to be 'as fast as possible' were identical, which may contribute to attentional failures in extended work shifts and during nighttime work shifts.

TL;DR: Data indicate that the difference between the fastest and slowest RTs was particular sensitive to detect very early effects of growing sleep pressure, and decrements in PVT performance which were related to circadian phase did not depend significantly on any categorization (such as percentiles of the RTs).

TL;DR: The data demonstrate that changes in FLA during wakefulness are to a large extent determined by the sleep-wake dependent process with little circadian modulation, and reflect differential levels of sleep pressure in the awake subject.
