In 1971 I discovered a shortcut. In research experiments student volunteers were exposed to a number of relaxation methods as their EEG was monitored to see which exercises produced the most phase-synchronous alpha. Some were asked to visualize peaceful scenes and locations. Some listened to their favorite music. Others tried fragrances, negative-ion generation, and colored lights. Some of these things had a mild alpha-enhancing effect; most had very little impact. One day I tried a standard twenty-item relaxation inventory. During the first few questions—imagine a dewdrop on a rose petal or a cascading waterfall, for example—their EEG manifested little change.
Then I asked. “Can you imagine the space between your eyes?” Boom. The pens scribbled the symmetrical waves of high-amplitude alpha. A subsequent question was, “Can you imagine the space between your ears?” Again, boom, high-amplitude alpha appeared instantly.
When either of these “space”-related questions was asked, subjects almost invariably generated a significant increase in alpha brain synchrony in the brain sites being monitored. No other question or imagery brought about such profound changes in the EEG. “Objectless imagery”—the multisensory experience and awareness of space, nothingness, or absence—almost always elicits large amplitude and prolonged periods of phase-synchronous alpha activity.
NeuroFeedback During the SOTT talk radio broadcast on Sunday 3rd November 2013 Nora Gedgaudas talked a lot about a science for training the human mind called NeuroFeedback. In this article I shall attempt to deliver a very concise description of this science. The medical science in depth is...
