Question

Quizplus · Accepted Answer

EEG stands for electroencephalogram, which is a technique that involves affixing electrodes to the scalp to measure electrical activity in the brain. It is commonly used in sleep labs to measure the different stages of sleep based on the patterns of beta, alpha, theta, and delta waves. MRI, PET, and CT scans are imaging techniques that are not typically used to measure brain wave activity during sleep.
