Dr. Stuart Twemlow, a psychiatrist and a research associate of the Monroe Institute, reports that: “In our studies of the effect of the Monroe tape system on brainwaves, we have found that the tapes encourage the focusing of brain energy (it can be measured as with a lightbulb, in watts) into a narrower and narrower ‘frequency band’ . This focusing of energy is not unlike the yoga concept of one pointedness, which we may translate in western terms as a single—mindedness.”
