qEEG can also be used for the localization of active structures, also referred to as brain source localization. One method is the use of standardized Low Resolution Electromagnetic Tomography (sLORETA, Pascal-Marqui 2007), where the 3-D distribution of electric neuronal activity in the brain can be shown based on the qEEG. This process of source estimation with the help of EEG is helpful to understand physiological, pathological, mental, functional abnormalities and cognitive behaviour of the brain.

Neuro-imaging techniques such as standardized Low Resolution Electromagnetic Tomography (sLORETA) can map the actual sources of the cortical rhythms. These advanced approaches are changing our understanding of the dynamics and function of the human brain.

How is it measured?

Using the same equipment approved for academic research, LoRETA allows to identify (and ultimately train) brainwave patterns from deep brain structures, using a standard sensor cap with advanced source-correlation software.

Being able, for the first time, to both identify and train these deeper structures in the brain is a major leap forward in brain mapping, and is what enables 3D neurofeedback.
