SPECTRAL ANALYSIS
With the EEG data stored on computer sophisticated software programs are then used by Dr. Rozelle to visually examine the brain wave paterns, re-montage the data channels for different views and source localization, and perform statistical analyses. Topographical mapping provides vivid visual displays of how the electrical power in the brain is distributed.
DATA BASE ANALYSIS
The EEG data can then be compared to a Normative Data Base matched for age, gender, and handedness on measures of coherence, phase, amplitude asymmetry, and relative power. A Traumatic Brain Injury or Learning Disability Discriminant Analysis can also be performed. Low Resolution Tomography (LORETA) employs vector calculus to surface recordings to locate the electrical source generators. Three dimensional views can be created to enhance and complete the picture. The QEEG is a great tool for neurotherapy protocol development and quantifiable results.
