Generally, microsleeps are characterized by a decrease in activity in wakefulness-related regions of the brain and an increase in activity in sleep-related regions of the brain. Looking at neural correlates of microsleeps is difficult because microsleeps can also be triggered by monotonous tasks (e.g. such as driving or dozing off in class).
Hori et al. regard sleep onset hypnagogia as a state distinct from both wakefulness and sleep with unique electrophysiological, behavioral and subjective characteristics, [10] [12] while Germaine et al. have demonstrated a resemblance between the EEG power spectra of spontaneously occurring hypnagogic images, on the one hand, and those of both ...

It keeps us from dozing off to sleep for the whole day, but it also allows us to take it easy when it's time to get up without the fear of not making it to work or school in time.
Actigraphy can assess sleep/wake patterns without confining one to the laboratory. The monitors are small, wrist-worn movement monitors that can record activity for up to several weeks. Sleep and wakefulness are determined by using an algorithm that analyzes the movement of the patient and the input of bed and wake times from a sleep diary.
Finding the right sleep sound is a bit like finding the right type of pajamas, says Dr. Winter. And while research on the sleep benefits of different noise types is limited, it’s definitely growing.
