Neurodiagnostic Testing and Monitoring

Neurodiagnostic Tests

Neurodiagnostic tests track electrical activity in the brain and nervous system to aid in the diagnosis and evaluation of neurological problems. Our neurodiagnostics team, which is based at St. Luke’s Boise Medical Center, offers three types of testing.

Please contact your primary care physician for a referral.


Electroencephalogram (EEG)

Electroencephalography (EEG)

An electroencephalogram (EEG) is a test that measures and records the electrical activity of your brain. Special sensors (electrodes) are attached to your head and hooked by wires to a computer. The computer records your brain's electrical activity on the screen or on paper as wavy lines. Certain conditions, such as seizures, can be seen by the changes in the normal pattern of the brain's electrical activity.


Evoked Potential Test

Evoked Potential (EP)

This test records electrical activity from the brain, spinal nerves, or sensory receptors in response to specific external stimulation. Electrodes are applied to the scalp and other areas of the body and a series of stimuli is introduced. Hundreds to thousands of responses are received, amplified, and averaged by a computer. Evoked potentials are helpful in evaluating a number of different neurological problems, including multiple sclerosis, spinal cord injuries, acoustic neuroma, and optic neuritis. Each type of EP looks at a different neurological pathway: auditory, visual, and somatosensory.


Our specialists diagnose and treat epilepsy, stroke, multiple sclerosis, Parkinson’s, and other neuromuscular diseases.
