Recorders, Physiologic, Evoked Potential, Somatosensory

Definition : Evoked potential (EP) physiologic recorders designed for detecting, amplifying and recording the bioelectric response of the central nervous system (brain and/or spine) in response to electric stimuli applied on or through the skin near an appropriate nerve fiber. These recorders typically include signal amplifiers; filters (to suppress interference); memory (e.g., electronic or optical/magnetic disc); a display; and detachable electrodes that are usually placed on appropriate locations characterized by anatomic landmarks (e.g., standard EEG positions on the head, midline of the spine). Cephalic bipolar montages are relatively free from noise and are preferred for routine clinical use. EP recorders usually include capabilities to deliver external or transdermal electrical stimuli appropriate to elicit the bioelectric response needed for recording. Somatosensory EP recorders are used in clinical studies of the spinal cord and upper and lower limb pathways and in assessment of the status of comatose patients.
