from Wikipedia, the free encyclopedia

The electrophysiology is a partial area of the neurophysiology , which deals with the electrochemical signal transmission in cells and tissues involved.

Which one is different clinical electrophysiology from the medical field of neurology and cardiology of the experimental electrophysiology from the research field of physiology and especially neurophysiology and muscle physiology .

The neurologists' electrophysiological measurements provide information about damage to entire polysynaptic nerve tracts and peripheral nerves. Methods include electroencephalography (EEG), the measurement of evoked potentials (somatosensory, motor, visual or acoustic evoked), electroneurography and electromyography (EMG). Cardiologists examine the electrical currents on the body surface ( electrocardiogram (EKG)) and as part of a special cardiac catheter examination , the electrophysiological examination (EPU)Heart muscle .

As part of experimental neuro- and muscle physiology , the electrical properties of individual nerve cells or muscle cells or associations of such cells are examined. Methods of experimental electrophysiology are, for example, the manual and automated patch-clamp technique , staining with voltage-dependent dyes and measurements using a multi-electrode array .
