Basic facts about different Brain Maps

  • All brain maps are EEG recordings of brainwave activity at particular sites across the scalp.
  • There exists an internationally recognized placement of 19 sites or channels across the entire head, which all should be measured.
  • Basic brain maps measure amplitude or the “volume” of the brainwaves.
  • More advanced QEEG brain maps analyze coherence, or the “speed of connectivity” between the sites in addition to amplitude data.
  • More recently, an even deeper level of analysis, called LORETA imaging, can now look deeper beyond amplitude and coherence measures.

What is qEEG?

The Electroencephlograph is a device that measures electrical-chemical reactions of neurons across the scalp of the cerebral cortex (outer brain). Tiny cup-like sensors capture the signal which is then amplified by the EEG machine. There are 19 sites which are universally accepted, allowing fellow doctors and clinicians to discuss specific regions and ensure everybody is on the same page.

Why Should You
Have a qEEG?

  • Areas of your brain could be working too hard or not hard enough
  • Discover the root causes to your symptoms
  • Most people's problems are beyond their thinking mind and are seen on qEEG Brain Maps
  • The qEEG can help determine if you are taking the right medications

What's the "q"
in qEEG?

The “q” in qEEG is for the quantitative analysis performed to the raw EEG data collected. Psychologists and Neurotherapists utilize additional software programs to identify areas of the brain that are under or over-activated, and look for correlations of these brain patterns that have been documented in psychological and/or behavioral concerns.
