In the "old days" of neurosurgery, surgeons relied almost entirely on their knowledge of anatomy and a steady hand to avoid damaging delicate nerves. While those skills remain the foundation of surgery, modern technology has added a high-tech "guardian angel" to the operating room: Intraoperative Neuromonitoring (IONM).
At IGEA Brain, Spine, Pain & Orthopedics, we consider nerve monitoring an essential component of many brain and spine procedures. By providing real-time data on your nervous system’s health, IONM allows our NJ and NY surgical teams to operate with a level of precision that was once unimaginable.
Think of IONM as a "check engine light" for your nervous system. During surgery, a specialized neurophysiologist uses a computer system to monitor the electrical signals traveling through your brain, spinal cord, and peripheral nerves.
If a nerve is stretched, compressed, or comes into contact with a surgical instrument, the IONM system alerts the surgeon immediately—often before any permanent damage has occurred. This allows the surgeon to pause, adjust their approach, and protect the nerve’s function.
The process begins after the patient is asleep under anesthesia. Small, specialized electrodes are placed on the scalp and various muscle groups in the arms or legs. These electrodes track three main types of electrical signals:

The primary goal of nerve monitoring is safety, but the benefits extend throughout the entire recovery process.
By monitoring motor pathways (MEP) during complex spine surgeries—such as those for scoliosis or spinal tumors—we can ensure that the spinal cord remains healthy throughout the entire procedure.
In cases involving scarring from previous surgeries or tumors that have shifted the normal anatomy, nerves may not be where the surgeon expects them to be. IONM acts as a GPS, helping the surgeon navigate safely around these vital structures.
When nerves are handled gently and protected from injury, patients typically experience less post-operative pain, less numbness, and a faster return to normal activities.
Technology like IONM allows our surgeons, including experts like Dr. Ciro G. Randazzo and Dr. David Poulad, to perform aggressive tumor removals or complex spinal reconstructions that might otherwise be considered too risky.
Implementing IONM requires a dedicated team. At IGEA Brain, Spine, Pain & Orthopedics, our surgeons work alongside board-certified neurophysiologists who are present in the operating room from the first incision to the final stitch.
Whether you are in Jersey City, Paramus, Union, Bedminster, or Manhattan, you have access to the highest level of surgical monitoring technology available in 2026.
Does nerve monitoring hurt?
No. The electrodes are placed while you are under general anesthesia, and they are removed before you wake up. You may have small, temporary marks on your skin, but the monitoring itself is painless.
Does IONM increase the cost of surgery?
While IONM adds a specialized service to the procedure, most insurance companies cover it because it is proven to reduce the risk of costly complications and long-term disability.
Is it used for every surgery?
Not necessarily. For very straightforward procedures where nerves aren’t at risk, it may not be needed. We will discuss whether IONM is recommended for your specific surgery during your consultation.
Neurosurgery is a journey of precision. If you are facing a brain or spine procedure, make sure you have the best "navigational tools" on your side. Contact IGEA Brain, Spine, Pain & Orthopedics to learn more about how we use technology to protect your future.
