1. Multiple Sclerosis

Magnetic resonance imaging (MRI) is an important method to capture pathological processes in the central nervous system in patients suffering from multiple sclerosis. However, those parameters which can be detected most easily, i.e. multiple sclerosis plaques in the white matter and contrast enhanced lesions, do not sufficiently correlate with the impairment of the patients. Thus, prognostic markers are lacking. In the past years we have employed MR imaging in longitudinal and therapeutic studies. Additionally, we have enhanced MR sequences and analysis methods in collaboration with physicists to gain new insights into the pathology of multiple sclerosis. We were able to show that local perfusion increase precedes new contrast enhanced lesions. Thus, new centers of inflammation can be detected earlier by employing perfusion-weighted imaging. We further found an association of disease related imaging activity with increased size of the Virchow-Robin spaces. This corroborates our experimental findings regarding the relevance of the perivascular space, in which obviously is determined whether a lymphocyte has auto-aggressive effects on the central nervous system. Our main focus is the investigation of inflammatory neural damage. Therefore, we use imaging techniques in humans and animals.

2. Vestibular System

Our research group focuses on the central representations of the vestibular system and its multisensory interconnections within the cortex. Animal experiments (sprague dawley rat) are performed using galvanic vestibular stimulation in FDG-PET. Examinations of healthy volunteers as well as patients with vestibular disorders in magnetic resonance imaging make up for the majority of our studies. Here, the potential methods include structural imaging (VBM) as well as functional neuroimaging (fMRI, DCM, resting state analysis and functional connectivity). Our repertoire of vestibular stimuli includes galvanic stimulation of the whole vestibular nerve, short tone bursts for otolith stimulation and caloric irrigation of the horizontal semi-circular canal.
