Journal ArticleDOI
An improved boundary element method for realistic volume-conductor modeling
TL;DR: An improved boundary element method (BEM) with a virtual triangle refinement using the vertex normals, an optimized auto solid angle approximation, and a weighted isolated problem approach is presented and the results are compared to the spherical-shells approximation.
Journal ArticleDOI
Improving source reconstructions by combining bioelectric and biomagnetic data
Manfred Fuchs,Michael Wagner,Hans-Aloys Wischmann,Thomas Köhler,Annette Theißen,R. Drenckhahn,Helmut Buchner +6 more
TL;DR: In this paper, a framework for combining bioelectric and biomagnetic data is presented, where the data are transformed to signal-to-noise ratios and reconstruction algorithms utilizing a new regularization approach are introduced.
Journal ArticleDOI
Comparison of realistically shaped boundary-element and spherical head models in source localization of early somatosensory evoked potentials
Helmut Buchner,Till Dino Waberski,Manfred Fuchs,Hans-Aloys Wischmann,Michael Wagner,R. Drenckhahn +5 more
TL;DR: Source localizations of early somatosensory evoked potentials and electrical potentials produced by dipoles in the region of the central sulcus were computed using realistically shaped boundary-element head models (BEM) and compared to localizations obtained using 3-shell spherical models.
Journal ArticleDOI
Postcentral origin of P22: evidence from source reconstruction in a realistically shaped head model and from a patient with a postcentral lesion
Helmut Buchner,T.D. Waberski,Manfred Fuchs,R. Drenckhahn,Michael Wagner,Hans-Aloys Wischmann +5 more
TL;DR: The present study used dipole localization within realistically shaped head models and constrained the inverse solution by using the individual cortex and the normals on it, as derived from MR-tomography, to find the source of the radial field of P22.
