Center for Electroneurodiagnostics (CEN)

Founded by Dr. T.V. Seshan, a Physical Medicine and Rehabilitation (PM&R) physician and pioneer in the field of IONM, CEN is committed to the training and placement of skilled and insightful surgical neurophysiologists.

CEN faculty advisors are senior clinicians with extensive experience in the most complex brain, spine, vascular and peripheral nerve surgeries. Each advisor is committed to providing students with the knowledge and tools necessary for success as an IONM technologist.


When a patient undergoes surgery, they cannot speak for themselves. No one knew this truth better than pioneering IONM physician, Dr. Thirumoorthi Seshan. Intraoperative Neurophysiologic Monitoring (IONM) was not only his expertise but also his passion. The Center for Electroneurodiagnostics (CEN) began from his vision of a healthier world — a place where people are empowered to speak up for those who cannot speak for themselves.

In the early 1980s, Dr. Seshan began utilizing methods to assist several prominent surgeons with pediatric scoliosis corrections. Recognizing the importance of IONM and its vital role in patient safety, Dr. Seshan saw tremendous value in sharing his knowledge with others. Because of this, he founded an IONM training program that would eventually become known as the Center for Electroneurodiagnostics. The program he birthed empowers individuals to keep patients safe from surgical injury and able to maintain their livelihood.

Dr. Seshan’s ultimate goal was to create a comprehensive educational program that encompassed all of the ideals necessary to create highly skilled surgical neurophysiologists. Today, CEN graduates many qualified and employable clinicians each year. At the time of his passing, Dr. Seshan alone had monitored thousands of cases. Now, because of his vision, CEN graduates will go on to monitor and protect thousands more.
