Question

Quizplus · Accepted Answer

EEG stands for electroencephalogram, which is a device used to monitor the electrical activity in the brain. This is the most commonly used tool for sleep research as it allows researchers to determine the different stages of sleep based on patterns in the electrical activity of the brain. MRI (magnetic resonance imaging) and PET (positron emission tomography) are imaging techniques used to visualize the brain, while CAT (computed tomography) is an imaging technique used to visualize organs and tissues in the body. None of these tools are specifically designed for sleep research.
