Question

Quizplus · Accepted Answer

The method described in the question is the electroencephalogram (EEG), which records the brain's electrical activity by placing electrodes on the scalp to detect brain-wave activity. PET, MRI, and fMRI do not directly measure electrical activity, but instead measure blood flow, metabolic activity, and magnetic fields, respectively.
