Which technique measures magnetic fields from the brain's natural electrical activity?

Question

Quizplus · Accepted Answer

MEG (Magnetoencephalography) is a technique that measures the magnetic fields produced by the electrical activity in the brain. It is similar to EEG (Electroencephalography), which measures the electrical activity, but MEG is more sensitive to activity in deeper structures and has better spatial resolution. Lesion techniques involve the intentional destruction of certain brain regions to study the effects on behavior, while PET (Positron Emission Tomography) is a brain imaging technique that measures blood flow and metabolism.
