Biofeedback is a technique you can use to learn to control your body's functions, such as your heart rate. With biofeedback, you're connected to electrical sensors that help you receive information (feedback) about your body (bio).
This feedback helps you focus on making subtle changes in your body, such as relaxing certain muscles, to achieve the results you want, such as reducing pain. In essence, biofeedback gives you the power to use your thoughts to control your body, often to improve a health condition or physical performance.
Neurofeedback (NFB), also called neurotherapy or neurobiofeedback, is a type of biofeedback that uses real-time displays of brain activity—most commonly electroencephalography (EEG), to teach self-regulation of brain function. Typically, sensors are placed on the scalp to measure activity, with measurements displayed using video displays or sound.

What is QEEG or Quantitative Electroencephalogram?
Quantitative EEG is the measurement of the electrical patterns that reflect cortical electrical activity or “brainwaves” at the surface of the scalp. Simply put, a QEEG uses the computer to measure your brainwaves, which we can analyze to determine how your brain is functioning. The QEEG can tell us an enormous amount of information about what's going on in your brain, and gives us a map of how we can address certain issues you may have such as anxiety or difficulty concentrating.
How is the QEEG done?
Using an Electro-cap with 20 active electrodes and 2 reference earlobes electrodes, the scalp electrical activity is collected by an EEG amplifier – Lexicor, Neurosearch-24 channel system. The electrodes are set following the 10/20 electrodes positioning. After artifact correction the electrical activity is analyzed using various montages. The raw data are then processed against a normative database and the results will present the amplitudes of various brain waves frequencies (Delta, Theta, Alpha, Beta) asymmetries, phase and coherence. The measure of connectivity or coherence is one of the most important parameters for brain functionality.
