Those are examples of physiological measure. An electromyogram (EMG) measures the electrical action of muscles very still and amid constriction. Nerve conduction thinks about measure how well and how quick the nerves can send electrical signs
An electroencephalogram (EEG) is a test used to discover issues identified with electrical movement of the cerebrum. An EEG tracks and records mind wave designs. Little metal plates with thin wires (anodes) are set on the scalp, and after that send signs to a PC to record the outcomes.
