![]() The patient is asked to relax with eyes closed and a second set of measures is taken with eyes opened. The recording is done while the patient is sitting in a chair. Each site is cleansed, and electrode paste/gel is placed under each sensor to ensure proper conductivity to read the patient's brainwaves. A multi-electrode recording of brain wave activity is recorded and converted into numbers.Ī QEEG consists of placing a cap with twenty electrodes/sensors on the patient's head, and ear clips on each ear lobe. 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". ![]() ![]() QEEG (Quantitative Electroencephalography) Brain MappingĮlectroencephalography (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.
