The scientific practice of neuromonitoring takes place in the surgical suite (OR). It aims to 1) reduce the risk to the patient of iatrogenic damage to the nervous system, and/or 2) provide functional guidance to the surgeon. To accomplish this, a specially trained member of the surgical team, for example a neurophysiologist, obtains and co-interprets triggered and spontaneous electrophysiologic signals from the patient as their surgery proceeds.
