ROS and its role in neurophysiology

Name of the thesis Reactive oxygen species and their neurophysiological role Aim of the thesis Aim of the theoretical part is to provide overview of reactive oxygen species (ROS) and show their place in organism - posstive and necessary effects for the organism on the one hand and source of serious diseases on the other hand. Futhermore, the theoretical part deals with the restoration balance between the production of free radicals and antioxidants protection. Theoretical part also deals with substance FeTTPS. Aim of the experimental part is to determinate whether the application of FeTTPS affects cerebral blood flow during trancallosal stimulation with increasing frequency. Futhermore, to determinate whether the applicatication of this substance affects the slope of the curve and threshold of evoked potencials and number and duration of afterdischargers. Research method The research took place at the premises of Onstitue of Physiology, Academy of Sciences, Czech Republic. Experiments were carried out on laboratory albine Wistar rats. General anesthesia was performed to rats, stimulating and sensing electrodes were implated in epidural area of sensorimotoor cortex and Laser Doppler flow probe was implated into the contralateral hemisphere. In the first part of experiment included 11 animals. We..
