First sleep-cycle gene discovered during study; Utah family: Finding could lead to new treatments for jet lag and insomniaASSOCIATED PRESS
However, the extent to which sleep affects responses along sensory pathways remains unclear. On one hand, responses to external stimuli in cortical sensory regions may be attenuated during sleep, given that perception of external events is rarely reported upon awakening, and stimuli are not ...

The closed-loop intervention had two modes of operation (Methods and Extended Data Fig. 3)—either (i) ‘synchronized (sync) stimulation’ (Fig. 1c) or (ii) ‘mixed-phase stimulation’—which were applied in two separate groups of participants. Sync-stimulation involved neocortical stimulation ...

Exposure to light during the day is key to a healthy circadian rhythm, which is the body’s internal clock regulating the sleep and wake cycle over 24 hours. Our brains use daylight and darkness to regulate this cycle — light means its daytime (time to be alert!) and dark means it’s...
以及The longer we sleep,the more time we spend in REM,which is why we are often dreaming when waking up in the morning.If we sleep less than seven hours,however,it becomes harder to achieve this level of REM.(我们睡得越久,在快速眼动阶段(做梦)的时间就越多,这就是为什么...

Abstract Summary: Behavioral and physiologic indices of arousal to auditory stimuli were examined during the first cycle of sleep in 8–12-year-old hyperactive children and nonhyperactive controls. No behavioral responses or sustained awakenings were obtained for any child during the first cycle of sl...
For example, babies and toddlers need a lot of sleep, since their bodies are growing and developing. During puberty, there are many hormonal changes going on, which can lead to disrupted sleep. And as you get older, hormone levels start to decline, which can affect the quality of your sle...
