A new study showed that people who took longer to enter this dream phase of sleep had higher levels of amyloid beta and tau, ...

The function of rapid-eye-movement (REM) sleep is still unknown. One prevailing hypothesis suggests that REM sleep is important in processing memory traces. Here, using positron emission ...

We ask an expert why REM sleep is so important, what happens if we don't get enough of it and how to get more REM sleep.

Prolonged rapid eye movement sleep latency may be an early indicator of Alzheimer’s disease and related dementias, according ...

With commercial EEG hardware, [Michael] is able to communicate ... he’s busy writing an algorithm that will detect REM sleep and play an audio track while he’s in a dream state to trigger ...

Sleep has different stages. If you do an EEG of a person, there are four stages of sleep and then there is a separate sleep called REM sleep, rapid eye movement sleep. And the dreaming happens in ...

All video-EEG polysomnography recordings were made with ... to determine which individuals had visible movements in REM sleep. The researchers then used an optical flow computer vision algorithm ...

Although they experience lots of REM sleep, it is unusual. Unlike in placental mammals, where the EEG is desynchronized with a low-voltage activity, monotreme REM sleep shows synchronized high ...

Scientists have discovered that rhythmic oscillations of a specific neurotransmitter play a vital role in clearing toxic proteins from the brain during non-rapid eye movement (non-REM) sleep. These ...

AI-powered algorithm can analyze video recordings of clinical sleep tests and more accurately diagnose REM sleep behavior disorder. A Mount Sinai-led team of researchers has enhanced an artificial ...
