Course main goalA basic understanding of bioelectric phenomena (like the Action Potential, the ElectroNeuroGram, ElectroEncephaloGram, ElectroCardioGram etc.) and their mathematical analysis, based on biophysical/mathematical source models and volume conduction theory.
Course descriptionIn this course the electrophysiologic and biophysical processes underlying the generation of bio-electrical activity in particularly the brain and the heart are presented in relation to the potential differences that can be measured on the body surface, the ENG, the EEG and the ECG, respectively. These electrical signals may provide information on the (patho)physiological condition of the corresponding organ. Also, the principles and practicalities of artificial neural stimulation are dealt with. As a general introduction the theory of volume conduction of ionic currents, based on the quasi-static expression of Maxwell's equations, is presented. This theoretical framework is then applied to nerves and neurons. The aim is to obtain a basic understanding of the electrical phenomena involved, emphasizing both on a quantitative description and a model-oriented approach. This knowledge will serve as well as a basis for understanding the clinical measurement methods of ENG, EEG and ECG, and to improve the methods for measurement and analysis of these bio-electrical signals. The course also serves as an introduction to the extensive international scientific literature on bio-electric phenomena.
