The following images show a deep brain excess at 28 Hz, revealed using three different methods. All images are based on z-scores of the voxel data when converted into current-source density. The agreement shows that each method is valid, and that comparable results can be obtained by using different databases. Both databases used here are registered with the FDA and are approved for spectral analysis of EEG and comparison with a normative sample.
