The device that provides a detailed, three-dimensional computer-generated image of brain activity by aiming a powerful magnetic field at the brain is called a(n) ______.

Question

Quizplus · Accepted Answer

The device described is a functional magnetic resonance imaging (fMRI) scanner, which uses magnetic fields to create detailed 3D images of brain activity by detecting changes in blood flow. EEG (A) measures electrical activity in the brain, while psychophysiological measures (B) can include a range of physiological responses such as heart rate and skin conductance. CAT scans (C) use X-rays to produce images of the brain, but do not show details of brain activity. Therefore, option D is the correct answer.
