Die Magnetoenzephalographie (MEG) wird in den nervenarztlichen Fachern vor allem fur Grundlagenforschung, fur die Epilepsiediagnostik und fur die Lokalisation funktioneller Hirnareale benutzt. Die funktionelle Lokalisationsdiagnostik hat sich zu eine

We investigated a co-registration algorithm using a contour-fitting procedure to integrate functional data from magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) for frameless stereotaxy. In fMRI the shape of the head was

In this study we investigated the spatial heterotopy of MEG and fMRI localizations after sensory and motor stimulation tasks. Both methods are frequently used to study the topology of the primary and secondary motor cortex, as well as a tool for pres

We used a current localization by spatial filtering-technique to determine primary language areas with magnetoencephalography (MEG) using a silent reading and a silent naming task. In all cases we could localize the sensory speech area (Wernicke) in

Intraoperative magnetic resonance (MR) imaging was used to evaluate the extent of a resection, mainly in pituitary, brain tumor and epilepsy surgery. This paper summarizes some of our experience gained in 300 patients, which were investigated by intr

OBJECTIVE Intraoperative image data may be used not only to evaluate the extent of a tumor resection but also to update neuronavigation, compensating for brain shift. To date, however, intraoperative magnetic resonance imaging (MRI) can be combined o

In this longitudinal study multichannel MEG was used to localize and to quantify focal pathological spontaneous neuromagnetic activity in six patients with transient ischemic attacks (TIA) and two patients with transient global amnesia (TGA). Slow (2

Epilepsy surgery candidates with extratemporal foci represent a particular diagnostic and therapeutic challenge, because of anatomic and functional features of the pertaining areas. In the last decade, novel developments in the field of electrophysio

Brain lesions may influence their border zones by moving, compressing, infiltration, edema or by a mixture of all. Sources of evoked and spontaneous activity in border zones can be localized by magnetoencephalography (MEG) giving information on the f
