By studying the ability of a one-dipole model to explain the magnetic field actually resulting from two dipoles, minimum requirements for a successful separation of two dipoles were explored. Two dipoles in different depths generally require a much h

By analyzing simulated neuromagnetic recordings with a 37 channel magnetometer system, it was shown that the accuracy of a dipole source localization is considerably improved if the standard least-squares fit procedure is replaced by a maximum likeli

This paper introduces the concept of the resolution matrix as the basis for an objective theoretical comparison of distributed linear inverse solutions to the neuroelectromagnetic inverse problem. In particular, we describe how figures of merit deriv

A dipole source analysis of repeated measurements of the auditory evoked field (AEF) elicited by 60 dB SL tonebursts confirmed the previous theoretical prediction that a maximum likelihood estimation technique reduces localization errors resulting fr

The concept of a resolution field provides a means to compare arbitrary estimators of a brain activity of interest (AOI), represented, for example, by the amplitude of a dipole at a certain location of interest with well-defined and known direction.

The goal of the study was to explore the most fundamental aspects of a magnetoencephalography (MEG)-based dipole source analysis. For that purpose, a MEG measurement with an ideal magnetometer system (providing the radial component of the magnetic fi

The dependence of the neuromagnetic source localization accuracy on the volume conductor model was studied by the analysis of measured magnetic fields generated by tangentially oriented dipoles in a realistically shaped skull phantom. When using a ho

A new method of filtering auditory brain stem responses (ABR), which is time-and intensity-dependent, is proposed. The epoch containing the averaged response is divided up into 128 overlapping segments and each segment is differently filtered. The ch
