People have been interpreting dreams for millennia, but the field of oneirology attempts to study them scientifically. One theory, supported by PET scan studies, suggests that dreams are a result of electrical energy that stimulates memories located in various brain regions. Current research in oneirology seeks correlations between dreams and the functions of these regions. What machine did the researchers who discovered the link between dreams and REM sleep use to measure brain activity?
