Introduction: electric, magnetic and electromagnetic effect in live beings and humans
Basics of electrophysiological effects: neural and muscle cells, electric effects on cell membrane, electrophysiological measurements on the cellular level, cells in brain, neurons and heart
Bioelectrical source in humans, tissue a conductor, measurements, simulations, modeling: dipole, volume source, volume conductor, source – field, forward and inverse problem (example of heart), double-domain model, effect of aniosotropy
Bioelectica and biomagnetic measurements: electrodes on volumetric conductor, measurements of biomelectrical potential differences, biomagnetic fields, SQUID magnetometer: one-channel and multi-channel versions, electromagnetic safety, ECG, MCG, EEG, MEG, EMG measurements – clinical applications, basic diagnosis from ECG and MCG measurements
Electric and magnetic signals from other electro-active organs: eye, digestive system, lungs
Electrical and magnetic stimulation: electric stimulation of the heart, heart defibrillation, functional nerve stimulation
Measurements of electric and magnetic properties of neurons: impedence volumetric methods, blood flow in extremities, measurements of the magnetic lung pollution, importance of the magnetic indicators in digestive system
