What is “Quantitative EEG” (QEEG)?
QEEG is one of the modern brain imaging techniques. Whereas PET and SPECT and fMRI scans look at how metabolic activity is distributed in the brain, the qEEG looks at how electrical activity is distributed over the scalp. In terms of imaging, nothing else is as fast in revealing brain activity as the qEEG. It is also completely non-invasive, and can be done in a clinician’s office. It is well suited to the needs of the Neurofeedback clinician. Often a qEEG will be recommended for clients with clients with brain injury or developmental disorders, in order to help determine the path toward improved function.
Reply: The core principle of QEEG lies in “precise and objective quantification” by computerized analytic and statistical techniques. It permits us to extract more precise information from the brain electrical activity than when using the conventional simple un-aided visual inspection of EEG signal.
