WebOf note, no distinctions were found for beta 1, beta 2, gamma, theta EEG bands, or theta/gamma frequency power ratio (all P>0.11). In spite of the fact that the mean perfusion in all the chosen ROIs was comparable between groups (all P >0.38), in the group with high a3/a2 power ratio, there is a steady pattern to a lower perfusion.
