… For the MEG, we used a BTI 1 148 channel whole-head system. Each magnetometer flux
transformer was modeled by means of a thin, closed conductor loop with a diameter of 11.5 mm…

We used computer simulations to investigate finite element models of the layered structure
of the human skull in EEG source analysis. Local models, where each skull location was …

In the current study, we provide compelling evidence to answer the long-standing question
whether perception is continuous or periodic. Spontaneous brain oscillations are assumed to …

For accurate EEG/MEG source analysis it is necessary to model the head volume conductor
as realistic as possible. This includes the distinction of the different conductive …

Transcranial direct current stimulation (tDCS) has been applied in numerous scientific
studies over the past decade. However, the possibility to apply tDCS in therapy of …

… Aydin and CH Wolters are with the Institute for Biomagnetism and Biosignalanalysis, University
of Münster, 48149 Münster, Germany. B. Lanfer is with the Institute for Biomagnetism and …

… As an example, the sensors of the whole head BTI-148-channel MEG system together
with the outer surface of the head model of figure 1 are shown in figure 3(a). A typical …

Objective. We investigate volume conduction effects in transcranial direct current stimulation
(tDCS) and present a guideline for efficient and yet accurate volume conductor modeling in …

The major goal of the evaluation in presurgical epilepsy diagnosis for medically intractable
patients is the precise reconstruction of the epileptogenic foci, preferably with non-invasive …

Diffusion-weighted magnetic resonance imaging is a key investigation technique in modern
neuroscience. In clinical settings, diffusion-weighted imaging and its extension to diffusion …
