7. EEGs Detecting Sleep Disorders

Because an EEG measures the electrical impulses in the brain, it is an effective test for detecting sleep disorders. During sleep, you are peacefully resting, but there is also an interplay of brain activity that moves you through various stages of sleep. Scientists discovered the different stages of sleep using an EEG in the 1950s by examining brain waves and measuring eye and limb movement.
