During non-REM sleep, participants received auditory cues to reinforce positive memories and reduce negative ones.

Being able to erase bad memories and traumatic flashbacks could help in the treatment of a host of different mental health issues, and scientists have found a promising new approach to do just this: ...

Every minute or so during non-rapid eye movement (NREM) sleep, the brain releases a wave of norepinephrine, a hormone that is one of the brain’s primary neurotransmitters. Norepinephrine is a ...

A study published in the Proceedings of the National Academy of Sciences journal found good news for people looking to forget ...

The frequency and duration of large muscle group leg movements during sleep change over time, and show distinct sleep stage differences.

The two phases of sleep include rapid eye movement (REM) cycle sleep and non-rapid eye movement (NREM) sleep. Sleep allows both our body and our cognition to go into a full resting period.

Brain waves and eye movements tell doctors about the timing of the different phases of sleep. The two broad phases of sleep are non-REM (non-rapid eye movement) and REM (rapid eye movement).

that combine during non-rapid eye movement (non-REM) sleep in mice. These oscillations power the glymphatic system—a brain-wide network responsible for removing protein waste, including amyloid ...

There is a dose-dependent relationship between alcohol and sleep, especially for REM sleep onset latency and REM sleep duration.

Upon analysing the data, it was found that two substages happened during the NREM (Non-Rapid Eye Movement) sleep. The pupils contracted in one phase, suggesting new memories were being replayed ...

It is known that while one sleeps, the brain 'consolidates' memory by integrating new information learnt during the day with previous knowledge. Critical to this is the process of 'memory replay', in ...
