Neurophysiology Laboratory

The Neurophysiology Laboratory at University Medical Center of Princeton at Plainsboro provides sophisticated diagnostic services for detecting a wide range of neurological disorders and conditions.

Our services include:

  • Electroencephalograms (EEG)
  • Long-term epilepsy monitoring (LTM)
  • Evoked potentials
  • Intraoperative monitoring

The technologists and electroencephalographers who work in our lab are highly skilled professionals. They perform and interpret a complete range of neurodiagnostic tests that assist physicians in the diagnosis of various neurological conditions. These conditions include seizure disorders, headaches, brainstem dysfunctions and other disorders affecting the nervous system.

Electroencephalogram (EEG) 

An EEG is a non-invasive procedure that traces the brain's electrical activity. During the procedure, electrodes are placed on the scalp to study brain function. University Medical Center of Princeton at Plainsboro performs EEGs utilizing the latest digital and video technology, recording up to 32 channels of EEG and video at the same time. Our state-of-the-art digital technology allows each patient's data to be analyzed electronically, ensuring highly accurate results that are critical to diagnosing seizure disorders, headaches, dizziness, stroke and fainting episodes.

Sleep EEG

Sleep EEG is used in children and adults to diagnose different types of seizures. Often the EEG rhythms recorded during sleep can serve as a follow-up examination to an EEG that was performed while the patient was awake as a way to rule out or detect abnormal sleep patterns. Mild sedation or other methods, such as sleep deprivation, may be used to help patients relax and sleep.

Long-Term Epilepsy Monitoring (LTM)

The Neurophysiology Lab works cooperatively with the Epilepsy Program at University Medical Center of Princeton at Plainsboro to provide the most comprehensive care to patients who are admitted to our long-term monitoring unit.

LTM is an inpatient procedure that simultaneously records EEG and video over extended periods of time. Highly sophisticated and precise, long-term monitoring pinpoints electrical activity in the brain during seizures. The results help identify the origin, type and frequency of seizures. They also assist in the development of an individualized plan of treatment. This inpatient procedure is an option for individuals whose seizures are not responding to outpatient treatment or those who require more insight into the cause of their seizures.

The Epilepsy Program provides a full range of evaluation, diagnostic and treatment services for children (8 years and older) and adults with seizure disorders.

Evoked Potentials

The Neurophysiology Lab offers evoked potential studies. These studies are used to measure electrical signals along nerve pathways.

Visual Evoked Potentials -- Help diagnose visual losses due to damage of the optic nerve and hysterical blindness, when the loss of vision is not associated with nerve damage.

Brainstem Auditory Evoked Potentials -- Help diagnose hearing losses, distinguishing between damage to the acoustic nerve from damage to the auditory pathways within the brain stem.

Somatosensory Evoked Potentials -- Help diagnose nerve damage or degeneration within the spinal cord or nerve roots.

Intraoperative Monitoring

The Neurophysiology Lab provides intraoperative monitoring, at the request of surgeons, for those patients who require professional monitoring of changes in brain, spinal cord and peripheral nerve function during surgery. Our goal is to help enhance safety and ensure successful outcomes for patients who are undergoing surgical procedures at University Medical Center of Princeton at Plainsboro.

Rapid Reports

The Neurophysiology Laboratory is committed to providing exceptional service and prompt reporting of results to your physician. Test results are normally mailed within 48 hours and can be faxed upon request.
