What is a qEEG Brain Map?

Like a fingerprint, your brain has a unique pattern of brain activity. A qEEG Brain Map, or quantitative electroencephalogram, is used to measure brain activity at 21 sites across your head. After recording your brain waves, we compare them to a normative database which then helps to identify and target problematic brain patterns.

By illustrating activity in critical areas of the brain (areas associated with everything from executive function, memory recall, vision, learning and balance) the qEEG serves as a diagnostic tool that guides counseling and neurofeedback. Subsequent qEEG maps can then be utilized to both monitor changes and optimize counseling and neurofeedback.

What are brain waves?

Different mental activities are associated with different electrical, or brain-wave patterns. The following lists the various frequency ranges produced by the brain and their respective mental states:

Delta – δ Deep meditation, dreamless sleep, suspended external awareness

Theta – θ Sleep and meditation, gateway to learning and memory, between sleep and wake

Alpha – α Resting state, quietly flowing thoughts, calm, alert, mind/body integration learning

Beta – β Attentive problem solving, judgement, decision making, focused mental activity

hiBeta – ηβ Highly complex thought, high anxiety or excitement, integrating new experience
