The relation of structure and function within the human cerebral cortex and its association with neuropathology as revealed in combination with animal models.

1. Abstract


A. According to our project description we maintained our line of investigation of the human cerebral cortex focussing on association areas of the parietal lobe and the extrastriatal areas of the visual system. The results have been published. These studies will be continued.

B. In collaboration with the Center for Epilepsy Bethel and the Institute for Neurophysiology University of Münster we continued our studies on heat shock protein expression in patients with epilepsy and in an animal model for tonic clonic seizures (PTZ model). For the latter we were able to show that astrocytes, which express the oxidative stress marker HSP-27 during the course of seizure episodes, become affected by a region-specific nitration and partial inhibition of glutamine synthase. These functional changes occur independently of quantitative changes in the amount of glutamine synthase. Therefore, future studies shall address the hypothesis, whether the observed seizure-induced nitration of the enzyme is part of an initially protective cerebral pathway in order to cope with seizure related phenomena of hyperexcitation. In addition, we started to address seizure and ischemia related changes of oligodendrocytes using oligodendrocyte specific stress markers.

C. We continued our studies on the receptors for nitric oxide, the soluble guanylyl cyclases (sGC) in the cerebral cortex of primates. In addition, we use now recently developed antibodies, which are specific for various regions within the sGC molecule to analyse the functional changes and role of sGC in development and neuropathology.

D. In vitro studies in combination with animal models for certain conditions known from hepatic encephalopathy. We analysed the mechanisms of ammonia induced NADH-oxidases and RNA oxidation in collaboration with the Clinic for Gastroenterology, Hepatology and Infectiology, SFB 575. This study will be continued.

E. In collaboration with the Institute of Anatomy of the University of Leipzig and the Max Planck Institute for Evolutionary Anthropology, Leipzig we studied the changes of the auditory nuclei within the brain stem (SOC) during the phylogeny of non-human primates in comparison to humans.
