Electrofiziologie
Electrofiziologie, or electrophysiology, is the branch of physiology that studies the electrical properties of biological cells and tissues and how these properties relate to function. It examines how membranes maintain resting potentials, how ion channels regulate currents, and how electrical signals such as action potentials are generated and propagated. The field covers excitable systems including neurons, cardiac and skeletal muscle, and sensory organs, as well as their interactions within neural and circulatory networks.
Techniques and instrumentation: Researchers use intracellular recording to measure membrane voltage, extracellular recording for population activity,
Applications: In cardiology, electrophysiology guides diagnosis and treatment of arrhythmias, supports ablation procedures, and underpins pacemaker
History and scope: Early experiments by Galvani and Volta established the electrical basis of muscle contraction;
