TL;DR: It is shown that astrocytic Ca2+ signals exhibit distinct features across the sleep-wake cycle and are reduced during sleep compared to wakefulness, and ablation of thisCa2+ signalling pathway impairs slow wave sleep.

TL;DR: In this article, the authors investigate statistical versions of such questions, by examining the number of battle-determined wars over time, and find that great wars become less violent over time.

TL;DR: Using two-photon imaging of naturally sleeping mice, sleep cycle-dependent PVS dynamics – slow, large-amplitude oscillations in NREM, a reduction in REM and an enlargement upon awakening at the end of a sleep cycle are demonstrated.

TL;DR: In this article, two different general strategies for not only estimating the break point τ but also complementing such an estimate with full confidence distributions, both for the change-point τ and for associated measures of differences between the two levels of θ, are examined.

TL;DR: In this article , the authors demonstrate sleep cycle-dependent vascular dynamics of pial arteries and penetrating arterioles: slow, large-amplitude oscillations in NREM sleep, a vasodilation in REM sleep, and a vasoconstriction upon awakening at the end of a sleep cycle and microarousals in both NREM and intermediate sleep.
