REM stands for rapid eye movement. According to a new study from the University of Surrey in England, REM sleep is often associated with memory and cognition. Surrey scientists collaborated with the UK Dementia Research Institute Centre for Care Research and Technology at Imperial College in London to use closed-loop auditory stimulation, which targets brain oscillations during sleep in a precise way. With this technology, the sounds from the closed-loop auditory stimulation are timed to hit brain waves at particular parts of the oscillation. For the first time, this was done during the REM period of sleep. The purpose of brain oscillations is to assist in the working of the brain and how it learns and retains information. Stimulating brain waves with sounds can increase the frequency and help scientists understand how brain oscillations in REM sleep can promote cognition and how REM sleep can be improved in those with dementia. This new technology and innovation can improve the memory functions of patients with dementia!
