Neurofeedback is a noninvasive program where the equipment measures your brain activity and compares it to the "normal" brain activity which was obtained from the research of thousands of brain activity maps from people with and without symptoms. Brain waves are measured by a computerized system called an electroencephalograph. The information is transfer from the leads placed on your head to a computer which translates your brain activity into a video display. For example, people with ADHD symptoms can have excessive slow wave activity in the frontal lobe, which indicates reduced frontal lobe activity. The neurofeedback system gives signals to the brain to enhance the frontal lobe activity by suppressing the slow wave activity and increasing the faster (higher) frequencies. This trains the brain to function in a more balanced and healthy way.
