Question

Quizplus · Accepted Answer

An EEG is an electroencephalogram, which is used to detect, amplify, and record electrical activity in the brain. It is often used in sleep labs to determine which stage of sleep a person is in. MRI and PET scanners are imaging tools used to visualize the brain, but they do not measure electrical activity. A fetoscope is a medical instrument used to monitor the health of a fetus during pregnancy and would not be used in a sleep lab.
