Subdural electrode as a dipole source for magnetoencephalography.
A subdural electrode was designed and constructed with 3 pairs of contacts to make 3 dipoles. The dipoles well approximate the expected magnetic behavior for a current dipole and can be used clinically to test localization capabilities of magnetoencephalography.
