Intraoperative Neurophysiological Monitoring (NIM) is a procedure used during certain surgeries of the nervous system, such as spine or brain. Its main purpose is to protect the patient’s neurological functions during surgery.

During surgery, electrodes are placed on specific areas of the body, such as the muscles, spinal cord or brain. These electrodes record the electrical activity of the nervous system and send this information to a monitor. The medical team interprets this data in real time to assess the functional integrity of the nervous system during the operation.
