Brain Mapping (qEEG)

Learn About Your Brain’s Vital Connections and Activity

A Map Of Your Brain’s Electrical Activity

Brain mapping, also known as quantitative electroencephalogram (qEEG), records the brain’s electrical activity at multiple sites on the surface of the scalp. By comparing the results to a database of healthy normal individuals the same age as the client, we are able to develop a treatment protocol that specifies sites on the scalp and brain wave elements to be trained.

What happens during a brain mapping (qEEG)?

A brain map is generated by recording of your brain’s electrical activity through tiny sensors at different parts of your brain. First, we will clean your forehead and ear lobes with alcohol to remove skin oils. Ear clips will be placed on your ear lobes. A special cap made of stretchy material will be placed on your head. There are 19 small holes in the cap that will be filled with a gel. You may feel a cool but pleasant sensation at the points where the gel is placed. The cap is connected to the EEG equipment through a set of wires and your brain waves will be visible on the technician’s computer screen. The brain mapping test itself has two parts.

We will record your brain waves with your eyes open for approximately 5 minutes, and with your eyes closed for approximately 5 minutes. We will ask you to sit and relax–limit your movement in the chair, avoid excessive swallowing, and minimize any form of muscle tension as much as possible. It often helps to pretend like you are on the beach or getting a massage.

Later, the results are analyzed to create a multi-color brain map that will be sent to Dr. Fotuhi. He will then review these results with you in person at your new patient appointment.

How should I prepare for the test?

For the days preceding your scheduled test, you should keep in mind the preparations listed below:

  • Do not drink caffeinated beverages the day of the test
  • Do not drink alcoholic beverages for 2 days before the test
  • Make sure your hair and scalp are completely dry prior to the exam
  • Shampoo your hair, but do not use conditioner
  • Do not apply hair products (e.g., hair spray, gel, mousse)
  • Remove all hair accessories (e.g., extensions, hair pieces, bobby pins, hair ties, earrings, etc.)
  • Do not work out or jog immediately before the test (light activity is okay)
  • Do not stay up late the night before the test

I am feeling sick. Should I cancel?

If you are experiencing the following symptoms, please call the office to reschedule your appointment. We would like to ensure that the results are as accurate as possible and the following conditions have the possibility of altering the results.

  • Sickness, fever, coughing spells, nasal issues, eye infections, ear infections, etc.
  • Taking newly prescribed medications or over the counter medications that you have not yet discussed with Dr. Fotuhi
  • Unusual disruption of your usual sleep pattern (loss of sleep)
