Question

Quizplus · Accepted Answer

The description provided in the question matches with functional magnetic resonance imaging (fMRI) which uses a powerful magnet to detect changes in blood-oxygen levels in different areas of the brain, indicating neural activity. EEG (A) and ERP (B) use electrodes on the scalp to detect electrical activity in the brain, whereas MEG (C) uses sensors to detect the magnetic fields generated by neural activity.
