Analyzing the Brain

Brain Maps, Part 2: Analyzing the Brain




A Brain Map is an EEG recording that identifies specific brain areas that are malfunctioning, pinpointing exact brain waves that cause problems to occur in mental and emotional behavior, and of confusion and loss of memory.

A brain map uses advanced state-of-the-art computer equipment that measures and displays the electrical wave patterns generated by the brain.  These patterns are then compared against a database of patterns to determine what areas of the brain are generating electrical wave patterns within the “normal” range and what areas of the brain are generating wave patterns that are in the “abnormal” range .  A map of these pattern comparisons is created to identify which areas of the brain need to be corrected and re-trained to move toward normal neurological functioning.

“An EEG Brain Map provides additional information that cannot be identified in a visual evaluation of the standard EEG.” -stated by Jay Gunkelman, EEG Specialist in California.

Of all the imaging modalities, the greatest body of replicated evidence regarding psychiatric and developmental disorders, has been provided by EEG and Brain Map EEG studies.” Dr. John R. Hughes, M.D., Ph. D. and E. Roy John, Ph.D. Of the University of Illinois School of Medicine, and the Brain Research Laboratories, New York University Medical Center.

Obtaining EEG Brain Maps

Brain Mapping and Neurofeedback begin with an individual having a Quantitative EEG, also known as a qEEG or QEEG, to evaluate brain function. The EEG stands for electroencephalogram, and measures fluctuating electrical activity in the brain’s hemispheres.  The purpose of a Brain Map is to see what is happening in the brain, that might be causing a person to have problems.  Then, the Brain Map information is used to set up a treatment plan of action with Neurofeedback sessions.

The method of obtaining an EEG Brain Map consists of placing an elastic cap on the head that contains 20 small electrodes that make contact on the scalp, and measure and record the electrical activity in different parts of the brain. This is much like a physician listening to your heart from the surface of your skin.  Instead, we are “taking a picture” of your brain’s activities from the surface of your scalp.  The EEG procedure is measuring the electrical activity and is totally noninvasive.  The electrodes are used for the measurement of the brain’s electrical activity.

The brain’s EEG activity is relayed from the scalp to the computer where it is recorded and stored.  All of this is done while the patient is resting quietly with his or her eyes closed, or sometimes during a performance of a cognitive task, such as reading.  The process takes about 1 and 1/2 hours, and is done according to the 10-20 International System shown below.  Research has found that the EEG has high reliability, equal to or superior to routinely used clinical tests such as mammograms, cervical screenings, and CAT scans.

The locations of the electrodes are shown in the chart below.
