Thematik

The interpretation of the electrical signals from patients is not merely a matter of memorizing a few characteristic pictures; there are many unusual variations and combinations of these phenomena which must be studied, analyzed, and correlated one with another and with other available data before any definite conclusion is possible. These situations demand some acquaintance with the electrical and physiologic principles by which they are determined.

The purpose of the course is to understand the origin of the electrical signals that can be recorded from excitable living tissues, the basic properties of their behavior, the main physical and physiological processes by which these signals (action potential, ECG, EEG, event related potentials, R triggered potentials, field potentials, intracellular and extracellular single unit recording) are determined. The course includes the discussion of the physical basis of electricity, resting potential, passive and active properties of the excitable membrane, voltage and ligand gated ion channels, realistic and abstract neuronal network models, the nature of the intra and extracellular signals. The origin and the physiological significance of the diagnostically important electrical signals (ECG, EEG, EMG, VEP) will also be discussed, some clinically relevant topic will also be touched.
