Electrophysiology

Electrophysiology is a part of neurophysiology, which deals with the electrochemical signal transmission in the nervous system.

One differentiates the clinical electrophysiology in the medical field of neurology of the experimental electrophysiology in the research field of physiology and in particular neurophysiology and muscle physiology. The electrophysiological measurements of neurologists provide information on all polysynaptic damage nerves and peripheral nerves, whereas the experimental neurophysiology describes the electrical properties of individual nerve cells or muscle cells or associations of such cells.

Methods of neurological electrophysiology are eg electroencephalography (EEG ), the measurement of evoked potentials ( somatosensory, motor, visual or auditory evoked ), the electroneurography and electromyography ( EMG).

Methods of experimental electrophysiology are, for example manual and automated patch clamp technique, staining with voltage-sensitive dyes and measurements using multi-electrode array.
