Medicine & Inventions: REM Sleep

Learn about REM sleep with iMinds insightful knowledge series.

REM is an important component of sleep. But sleep itself is a difficult phenomenon to study, because it is such an insular process. Dreams in particular are highly elusive for the researcher of sleep. As dreaming is a "state of mind", theories concerning it are frustratingly convoluted and highly theory-based, with any advancement unlikely to be supported by hard evidence. However, what scientists can do is measure the physical reactions that take place in our bodies and by our bodies when we are sleeping. This helps us understand what happens to us when we sleep and what REM is all about.
