Clinical Neurophysiology Laboratory

In Clinical Neurophysiology, our team of specialists from Lurie Children's Division of Neurology analyzes and monitors the nervous system function to promote effective treatment of neurological diseases and conditions for our pediatric patients. Our specialists, including pediatric neurology physicians and neurodiagnostic technologists, record electrical activity arising from the brain, spinal cord and peripheral nerves using a variety of techniques and instruments.

Procedures Performed

  • Electroencephalograms (EEG)
  • Evoked Potentials
    • Brainstem Auditory Evoked Potentials (BAEP)
    • Somatosensory Evoked Potentials (SSEP)
    • Visual Evoked Potentials (VEP)
  • Electromyography (EMG) and Nerve Conduction Study (NCS)

How to Prepare for an EEG

The night before the EEG, wash your child’s hair with shampoo. Do not apply conditioner or other hair products and please remove any braids or hair extensions.  The technologist must be able to apply the electrodes directly on your child’s scalp.

We do not sedate children for this test because sedative drugs affect the brain activity. We recommend sleep deprivation to facilitate sleep and to increase the likelihood of seeing EEG abnormalities relevant to seizure disorders. The night before the test, please ensure your child only sleeps for 4 hours or less.  For example, the child can sleep only from midnight until 4 a.m.  After that time, the child must be kept awake. This is extremely important in order to guarantee an optimal EEG recording. The lack of sleep puts stress on the individual’s nervous system, allowing the abnormalities to be recorded.  

How to Prepare for an Evoked Potential

The night before the Evoked Potential, wash your child’s hair with shampoo. Do not apply conditioner or other hair products and please remove any braids or hair extensions. The technologist must be able to apply the electrodes directly on your child’s scalp. Do not apply creams or lotions on your child’s arms or legs.

A neurodiagnostic technologist will call with specific instructions based on your child’s age and type of Evoked Potential being performed.

How to Prepare for an EMG/NCS

For an EMG/NCS exam the child must wear long sleeve shirts, long pants and socks to keep limbs warm prior to testing.

Referrals/Scheduling an Appointment

To schedule an EEG/EMG/NCS, your child needs a referral or an order by a primary care doctor or referring Physician/Advanced Practice Nurse/Physician Assistant. Please fax all testing orders to 312.227.9798.
