Question

Quizplus · Accepted Answer

Sleep activity is usually measured using an EEG (Electroencephalogram) machine, which records the electrical activity in the brain during sleep. MRI and PET scanners are not typically used to measure sleep activity. A fetoscope is a tool used for monitoring and listening to fetal heartbeats during pregnancy, and is unrelated to measuring sleep activity.
