Quantitative EEG (QEEG) is a method of analyzing brain wave patterns measured by EEG. The electroencephalogram (EEG) is a measure of the electrical activity in the head. Millions of neurons fire small, electrical signals as different brain regions communicate. Electrical activity in your brain is responsible for your daily experience as you sense the world around you, remember the past, make decisions, and carry out actions in the present. EEG is a non-invasive test that uses 19 electrodes on the scalp to measure the electrical activity generated by the brain. Traditionally, EEGs are performed to assess for seizure disorders.
QEEG is an additional perspective to the EEG. EEG data can be analyzed by comparing person’s actual EEG data to an EEG database and computing a statistical comparison between the two, which is known as QEEG. The comparison is displayed in colorful brain maps, where warmer colors indicate increased amounts of brainwave patterns and cooler colors indicate decreased amounts. Neutral or green indicate patterns that are within expected ranges in a “Goldilocks” zone where things are “just right.” These maps provide insight to an individual’s brain function, which can provide biological support to a neurological or psychological condition. Many people find the brain maps validate how they are feeling.
