Clinical neurophysiology

Clinical neurophysiology is a medical speciality that studies the central and peripheral nervous systems through the recording of bioelectrical activity, whether spontaneous or stimulated.

In some countries it is a part of neurology, whereas in others (such as Spain, Italy, the United Kingdom and Finland, for example) it is an autonomous field.

Its main parts are:
 * Electromyography and nerve conduction study (EMG/NCS)
 * Electroencephalography
 * Evoked potentials
 * Polysomnography
 * Intraoperative monitoring, also called IOM, Intraoperative neurophysiology monitoring, IONM, surgical neurophsyiology
