Clinical neurophysiology involves the study of the nervous system and its functions, including the brain, spinal cord, and nerves. Synonyms for clinical neurophysiology can include electrophysiology, neurodiagnostics, and neurophysiological testing. Electrophysiology refers to the measurement of electrical activity in the nervous system, while neurodiagnostics involves the use of imaging and other tools to diagnose neurological disorders. Neurophysiological testing may include a wide range of techniques such as electromyography, electroencephalography, and nerve conduction studies. Whether studying nervous system disorders, monitoring brain activity, or assessing nerve function, clinical neurophysiology is a critical part of modern medicine.
