ABSTRACT
Neurology is the branch of medicine dealing with all aspects of the nervous system. At least two types of electrophysiological measurement are usually made in a department of neurology; these are electroencephalography (EEG) and electromyography (EMG). EEG measurements can help in the diagnosis of epilepsy and are also useful in the investigation of brain tumours and accidental damage to the brain. EMG is usually taken to include both the recording of electrical signals from muscle and also the measurement of neural function using techniques such as nerve conduction measurement. EMG measurement is used in the diagnosis of muscle disease such as muscular dystrophy and also in the investigation of nerve damage which has resulted either from disease or physical injury.
