Two of them have not been discovered and physiologically explained yet. The most powerful of these phenomena relates to mental status. It has frequencies from 0.25 to 0.5 1/beat and peak 0.35 1/beat. Despite of difference of the peak frequencies the waves of factor loadings are overlapped. Therefore, regression models would be more fit for useful evaluation of mental status, rather then power of spectral density within any frequency range.
