EEG/MEG Error Bounds for a Dynamic Dipole Source with a Realistic Head Model

Abstract:

This work presents the background and derivation of Cramér-Rao bounds on the errors of estimating the parameters (moment and location) of a dynamic current dipole source using data from electro- and magneto-encephalography. A realistic head model, based on knowledge of surfaces separating tissues of different conductivities, is used.

Keywords:
