qEEG

The NeXus qEEG solutions offer deep insights into brain function by measuring and analyzing EEG activity on 19 locations. qEEG stands for quantified EEG. By quantifying EEG activity in different brain areas, the activity in these areas and their interaction can be shown, both numerically and visualized with color coded maps. The EEG and the derived qEEG information can be interpreted and used as a clinical tool to evaluate brain function, and to track the changes in brain function due to various interventions such as neurofeedback or medication.

qEEG data can also be compared to different qEEG databases and used as an assessment and prognostic tool and is also used for training. Brain mapping is a set of neuroscience techniques predicated on the mapping of quantities or properties onto spatial representations of the brain, which results in maps. One of the simplest forms of quantitative EEG is a spectral analysis. Most often qEEG refers to a recording and quantification of 19 or more positions, often through special EEG Caps. It can provide an overview of the dynamic changes that take place throughout the brain during cognitive processing tasks. This novel approach can be used to assist us in determining which areas of the brain are engaging and processing efficiently or not. To get a full physiological view and insights in mind-body interaction, true power lies in combining qEEG with other physiological signals such as Heart Rate Variability (HRV) and Skin Conductance (SC/GSR).
