Overview of Research Interests
Schwannomas and neurofibromas, also known as peripheral nerve sheath tumors (PNST), are benign tumors that arise from the nerve sheath of peripheral nerves. PNST are commonly solitary tumors, but they may occur in multiple areas of the body in Neurofibromatosis. Basic research includes genotype characterization of different disease phenotypes. A novel third type of recurrent NF1 microdeletion was shown to be mediated by nonallelic homologous recombination between low-copy repeats in chromosome 17q.
Benign brain tumors such as low grade gliomas may have different clinical evolution and prognosis. Molecular markers have been newly described with the support of the data base of the national glioma network program. Basic research on malignant brain tumors such as glioblastomas analyses the role of extracellular matrix and aquaporine on peritumoral edema formation. In addition, we have conducted in vitro and in vivo studies on hyperecin as intraoperative tumor visualization and a photodynamic therapy tool.
With introduction of a new intraoperative high field MRI (iMRI), studies are conducted to analyse intraoperative visualization of residual tumor: the role of perfusion-weighted imaging in a high-field intraoperative MR scanner. We are currently studying the results of high grade glioma surgery in a high-field iMRI – in terms of improvement of the extent of resection. Preoperative and intraoperative multimodal brain mappings are achieved by associating tools such as functional MRI studies, transcranial magnetic stimulation (TMS) and intraoperative electrophysiology.
The role of the cerebellum on biological motion processing was studied with fMRI examinations. It was shown that the cerebellum plays an important role in cognitive processes and motion processing, and that it communicates with right superior temporal gyrus.
The auditory (cochlear) nerve has no capability to spontaneously recover after injury. One of the reasons for this is just the fact that it contains central nervous system tissue and myelination is given by oligodendrocytes. The cochlear nerve differs tremendously from other cranial nerves, i.e. the facial nerve, which contain peripheral nerve myelin from Schwann cells. Regeneration of injured cochlear nerve in adult rats was analyzed following intrathecal application of antibodies against myelin-associated nerve growth inhibitor. Both morphological and electrophysiologial (auditory evoked potentials) investigations have shown some degree of regeneration, something which had never before been demonstrated.
The neuroprosthetics group of the Department of Neurosurgery implements invasive interfaces with human brains that are in diseased conditions in order to modulate pathological network activity and to decode ongoing oscillatory behavior for communication and therapeutic purposes. In parallel to these approaches this group conducts electrophysiological and neuroimaging studies to implement adaptive neuromodulation based on a physiological understanding of cortical networks. To support research in this rapidly developing field, a new Section on Translational Neurosurgery with its own “W3” professorship was created in the Department of Neurosurgery.
