Introduction to Magnetoencephalography (MEG)

Magnetoencephalography (MEG) is a completely noninvasive imaging technique used to measure the tiny magnetic fields produced by electrical activity in the human brain. Measurements are performed with extremely sensitive sensors called SQUIDS. A state-of-the-art MEG system has about 100-300 SQUIDS that are contained in a helmet-shaped dewar filled with liquid helium.
