Miami Neuroscience Institute Neurophysiology Department

In the simplest terms, neurophysiology is the study of nervous system function. With the aid of multi-modality diagnostic technology, our clinicians help patients of all ages who struggle with various conditions or syndromes, including multiple sclerosis, vertigo, brainstem strokes, seizures, acoustic neuromas, spondylosis and others. By investing in the latest equipment and a knowledgeable, experienced staff, Miami Neuroscience Institute has established some of the most advanced neurophysiology services in the Miami-Dade area.

The Neurophysiology staff collaborates with the Epilepsy Program, Intra-operative Monitoring (IOM) Surgery Services, as well as our neurologists and neurosurgeons to provide effective, coordinated care. Their goal is to help patients achieve excellent health outcomes.

Using Technology for the Benefit of Patients: Electroneurodiagnostic Services
The Neurophysiology Lab performs complete neurodiagnostic studies. Under the guidance of Medical Director Dr. Brad Herskowitz, the Neurophysiology staff conducts a variety of non-invasive studies to evaluate central and peripheral nervous system conditions. Neurophysiology services include:

  • Electroencephalogram (EEG)
  • Long-term Monitoring (Video EEG)
  • Ambulatory Monitoring
  • Evoked Potentials (EPs)
  • Electroencephalogram (EEG): Evaluates brain wave activity to evaluate brain health and functional ability. Typically, EEG evaluations last 20–45 minutes.

  • Long-term Monitoring (Video EEG): This testing method involves a 24-to 120-hour EEG that is recorded with continuous video to simultaneously record brain activity and clinical events. It is used with patients who are undergoing evaluation for seizures or non-epileptic seizures. The Neuroscience Institute has two specialized recording rooms for this purpose.

  • Ambulatory Monitoring: Provides a 24-hour EEG that allows the patient to engage in normal activities while it detects and records abnormal brain activity.

  • Evoked Potentials (EPs): Evaluate the interaction between certain neuronal pathways and the brain. EPs can be divided into the following categories:

  • Brainstem Auditory Evoked Potentials (BAEP): Tests a patient’s hearing pathway for acoustic neuromas and hearing loss. The patient listens to clicks while the activity is recorded.

  • Visual Evoked Potentials (VEP): Tests the visual pathway. Patients watch a visual stimulus, either a monitor with an alternating checkerboard pattern or they wear special LED goggles that stimulate the eyes with flashing patterns. The VEP is useful for evaluating and diagnosing optic neuritis or multiple sclerosis.

  • Somatosensory Evoked Potentials (SSEP): Tests the peripheral nervous system’s interaction with the central nervous system. SSEP uses a small stimulus to stimulate the median (wrist) nerve or Tibial (ankle) nerve. The SSEP then times how long it takes the stimulus to travel through the peripheral nervous system until the signal finishes in the brain. SSEPs are useful for evaluating lumbar and cervical spine problems and numbness, tingling or weakness in the hands, arms, feet or legs.

    Intra-operative Monitoring (IOM) Surgery Services
    When surgery is necessary, our neurophysiology team and surgeons partner to monitor the patient’s brain and spinal functions during surgery. This method is known as intra-operative neurophysiologic monitoring. Intra-operative monitoring helps protect vital brain and spinal cord function, even while the physician is surgically treating tumors and vascular malformations. This monitoring is managed by two specialists: a Board-certified neurologist and a credentialed Diplomat of the American Board of Neurophysiologic Monitoring. These experts provide continuous feedback to the surgeon as he operates. The Neuroscience Institute’s intra-operative monitoring team is one of the most skilled in Florida. Throughout the surgery, patients have an expert team and advanced technology working on behalf of their health and safety.
