Electromyography (EMG) is a general term meaning, the recording of the electrical activity of nerve and muscle. EMG is a diagnostic test used to assess the function of nerves and muscles. You may be sent for an EMG test if you are experiencing numbness, tingling, weakness, or pain. The test may take from 45 minutes to 1.5 hours depending on what your doctor has ordered.
Electroencephalography (EEG) is an electrophysiological monitoring method to record electrical activity of the brain. It is typically noninvasive, with the electrodes placed along the scalp, although invasive electrodes are sometimes used in specific applications. EEG measures voltage fluctuations resulting from ionic current within the neurons of the brain.
