Measuring Electricity in the Nervous System
The brain communicates with electrical impulses, which can also be sent to the spinal cord and nerves of the body. The measurement of these electrical impulses is called electrodiagnostic testing. Electroencephalography involves the measurement of activity in the brain. Nerve conduction studies follow electrical impulses in the nerves. Electromyography looks at electrical activity in the muscle. Learn more about these techniques and the diseases they can help identify.
How EMG and Nerve Conduction Studies Work
Electromyography (EMG) and nerve conduction studies (NCSs) are helpful tools neurologists use to investigate diseases of the peripheral nervous system and muscles. Learn more about how these tests are done here.
