Brain Mapping

Quantitative – QEEG – Brain Mapping

The process of taking a Quantitative Electroencephalogram (QEEG) is more commonly known as Brain Mapping. QEEG is the measurement, using digital technology, of electrical patterns at the surface of the scalp which primarily reflect cortical activity or “brainwaves”. When you come to the Center for Neurofeedback for a QEEG Assessment, we’ll simply fit a cap with 19 sensors over your head and measure activity with your eyes both open and closed. This information can then be used to plan the best form of Neurofeedback training for you or your family member. QEEG also provides additional information in the determination and assessment of ADHD and Learning disabilities than more traditional measures such as parent and teacher rating scales.

New state of the art dry electrode cap

New state of the art dry electrode cap! At the Center for Neurofeedback, Dr. Srednicki uses the latest technology in the field of Neurofeedback. This cap uses no paste or gels, is comfortable to wear and the set up is faster then using traditional gel based caps offering you a more positive experience.

Your brain is a constant hive of activity in which neurons fire and communicate using tiny electrical signals. QEEGs map the brain by monitoring this electrical activity in 19 different areas. By feeding this raw activity into a computer database and processing it, we can analyzed the electrical activity in your brain and compare it to other typical examples of activity in people of the same age and gender as you utilizing a national data base. At the Center for Neurofeedback we use Brainmaster Discovery and the ANSI Neuroguide Deluxe Data Base. Note the brainwave image below characterized by slow wave activity at the back of the head:

The data produced effectively form a route map for the brain. We can interpret the waves to understand how much activity is going on in each zone and decide whether it looks typical or in any way atypical or unusual. We can also depict the brainwaves of a QEEG into colourful maps. Note the example below depicting an anxious individual with excessive alpha and beta waves.

In many cases we frequently find that there are unusual levels of activity in certain areas of the brain. There can also be an imbalance, or perhaps a lack of connectivity. With this information, we can provide QEEG guided Neurofeedback that is particular to the individual in training and more targeted to parts of the brain.
