The authors of the study propose that our nightly slumbers evolved from the rise and fall of our tiny oceangoing ancestors, as they swam up to the surface of the sea at twilight and then sank in a sleepy fall through the night.

What is wakeful sleep?

These so-called polysomnographic recordings are used to define the states of wakefulness and sleep as follows (FIGURE 1): wakefulness is defined by low-voltage fast EEG activity (LVFA) and high muscle tone, NREM sleep is characterized by high-amplitude low-frequency EEG and decreased muscle tone, whereas REM sleep has …

What is rapid eye sleep?

REM stands for rapid eye movement. During REM sleep, your eyes move around rapidly in a range of directions, but don’t send any visual information to your brain. That doesn’t happen during non-REM sleep. First comes non-REM sleep, followed by a shorter period of REM sleep, and then the cycle starts over again.

They photographed 5 men and 5 women after a normal night’s sleep, and again after 31 hours of sleep deprivation.

When was the National Center on sleep disorders established?

National Center on Sleep Disorders Research National Center on Sleep Disorders Research Located within the Division of Lung Diseases of the NHLBI, the National Center on Sleep Disorders Research (NCSDR) was established in 1993 to foster the coordination of sleep and circadian research within NIH and other Federal agencies.

Who is known as the father of Sleep Medicine?

He is a leading authority on sleep, sleep deprivation and the diagnosis and treatment of sleep disorders such as sleep apnea and narcolepsy.
