Quizplus · Accepted Answer

EEG, or electroencephalography, uses electrodes placed on the scalp to detect electrical activity in the brain's surface. This is the only method listed that involves measuring electrical activity rather than blood flow or magnetic fields, making it the most appropriate choice for the scenario described. PET scans, fMRI, and TMS all use different methods to measure brain function.
