Sensory evoked potentials.
Small potentials, evoked by repetitive visual, auditory or somatosensory stimulation in the afferent pathways of the cord, brainstem or cortex, and detected by averaging signals from distant electrodes on the skin of the neck or scalp, can be used to investigate sensory loss or to detect clinically "silent" lesions in multiple sclerosis and other diseases.
