Quantitative EEG or Brain Map|Brain Changers

At Galveston Brain Changers, prior to beginning neurofeedback, we utilize an important assessment tool called the qEEG, or Brain Map. This provides a snapshot image of brain function that may be affecting symptoms, focus and relaxation. The qEEG provides the best information for neurofeedback training, as it helps the therapist isolate areas of brain function to target in treatment.

The EEG patterns from individuals are compared to others of the same/similar age in a “normative” database. The subsequent report helps identify where the differences are and how significant these differences may be from the “normal” sample group. Within the test, there are hundreds of measurements. The results are interpreted and analyzed by a specialist, and treatment protocols are then devised. One measure tested with the qEEG is called coherence. In simple terms, coherence measures how well communication is occuring within the brain itself. There is constant communication occuring between different areas of the brain at all times. If two areas are not communicating well (too little or too much), it can interfere with the efficiency of overall brain function. A qEEG is one of the few tools available that help assess coherence, and coherence can be positively influenced by neurofeedback.
