QEEG (Quantitative Electroencephalography) Brain Mapping
Electroencephalography (e-lec-tro-enceph-a-lo-graphy ~ EEG) is a assessment procedure that records the changes in electrical potentials (brainwaves, Delta, Theta, Alpha & Beta) in various parts of the brain. The EEG is a recording of the electrical activity of the brain from the scalp, using digital technology, of electrical patterns at the surface of the scalp which primarily reflect cortical activity or “brainwaves”. A multi-electrode recording of brain wave activity is recorded and converted into numbers.
A QEEG consists of placing a cap with twenty electrodes/sensors on the patient’s head, and ear clips on each ear lobe. Each site is cleansed, and electrode paste/gel is placed under each sensor to ensure proper conductivity to read the patient’s brainwaves. The recording is done while the patient is sitting in a chair. The patient is asked to relax with eyes closed and a second set of measures is taken with eyes opened. Preparation takes approximately 20-30 minutes and the actual EEG recordings take about 15 -20 minutes. QEEG Brain mapping is done using the New Mind Maps magnitude system.
Neurofeedback training, also referred to as EEG Biofeedback or Brainwave Training, is a form of operant conditioning during which the patient trains their own brainwaves. Neurofeedback presents the patient with real-time feedback on brainwave activity by sensors that are placed on the scalp. The sensors detect brain wave activity including Delta, Theta, Alpha and Beta. When brain activity changes in the direction desired by the neurofeedback protocol, a positive “reward”, typically in the form of a visual display and/or sound is given to the patient. Neurofeedback differs from other biofeedback techniques, in that the focus is on the central nervous system and the brain. Through the process of doing neurofeedback, the patient learns to train down, or train up certain brainwaves associated with a variety of disorders.
