MEG measures magnetic fields with millisecond resolution
Magnetoencephalography (MEG) measures the magnetic fields generated by current flow in the brain using superconducting coils bathed in liquid helium, giving the most sensitive non-invasive measurement of human brain activity at millisecond temporal resolution, which complements fMRI's superior spatial resolution.
