ABSTRACT:
An apparatus and method for the passive, non-invasive magnetoencephalographic (MEG) localization and tracking of sources of magnetic signals in the brain is disclosed. The apparatus and method uses a multi-axis magnetic gradiometer to detect the magnetic field, field gradient, and polarization emanating from neuronal sources in the brain under either normal or pathological conditions.
