Question

Quizplus · Accepted Answer

EEG or electroencephalogram is a device used to monitor the electrical activity of the brain over time. It measures the fluctuations in electrical activity using electrodes placed on the scalp, and can help diagnose conditions such as epilepsy, sleep disorders, and brain injuries. ESB (electrical stimulation of the brain) and TMS (transcranial magnetic stimulation) are techniques that involve the application of electrical or magnetic fields to the brain, but they are not used for monitoring brain activity over time. PET scans (positron emission tomography) are imaging techniques that show the function of the brain by measuring glucose metabolism, blood flow, or neurochemical activity, but they do not directly monitor electrical activity like EEG does.
