Theta/Beta Power Ratios (IMAGE) Maharishi International University Caption Theta/beta power ratios during computer tasks in the TM group decreased compared to the delayed-start group after 3 months TM practice and continued to decrease at the 6-month posttest in these subjects. In the delayed-start group theta/beta power ratios increased slightly from baseline to the 3-month posttest and then decreased sharply after they learned TM (3- to 6-month posttest).
