B)fMRI
C)PET scan
D)MEG

Question

Quizplus · Accepted Answer

MEG (magnetoencephalography) measures the electrical activity of brain cells directly by detecting the magnetic fields generated by the electrical currents in neurons. MRI (magnetic resonance imaging) and fMRI (functional magnetic resonance imaging) measure blood flow and oxygenation in the brain, while PET (positron emission tomography) scan measures glucose metabolism in the brain.
