Zen Gamma [from Scientific American Mind]

Researches at the University of Wisconsin Madison have found that during meditation, Zen Buddhist monks show an extrodinary synchronization of brain waves known as gamma sychrony - a pattern increasingly associated with robust brain function and the synthesis of activity that we call the mind. Brain waves are produced by the extremely low voltages involved in transmitting messages among neurons. Most conscious activity produces beta waves at 13 to 30 htz, or cycles per second. More intense gamma waves (30 to 60 ro even 90 htz) generally mark complex operations such as memory storage and sharp concentration. The Wisconsin study took electroencephalograms (EEGs) of 10 longtime Buddhist practioners and of a control group of eight college students who had been lightly trained in meditation. While meditating, the monks producing waves that were extremely high in amplitude and had longrange gamma synchrony - the waves from diparate brain regions were in near lockstep, like numerous jump ropes turning precisely together. The synchrony was sustained for remarkably long periods, too. The students' gamma waves were nowhere near as strong or tuned. Such results connote more than spiritual harmony; they reflect the coordination of otherwise scattered groups of neurons. Gamma sychrony increases as a person concetrates or prepares to move. And lack of synchrony indicates discordant mental activity such as schizophrenia. Finally, a growing body of theory proposes that gamma synchrony helps to bind the brain's many sensory and cognitive operations into the miracle of consciousness. That hypothesis certaintly agrees with the monks' gamma readings, seemingly confirming that Zen meditation produces not relaxation but an intense though serene attention. Trained musicisans also show superior gamma synchrony while listening to music - another form of calm but intense focus. -David Dobbs

neat! i remember reading in the autobiography of a Zen nun an incident where researchers hooked her up to machines while she meditated and were astounded by the results. there's surely more to the physics of meditation and prayer than meets the eye.

A review of Why God Won't Go Away from Amazon.Com

Over the centuries, theories have abounded as to why human beings have a seemingly irrational attraction to God and religious experiences. In Why God Won't Go Away authors Andrew Newberg, M.D., Eugene D'Aquili, M.D., and Vince Rause offer a startlingly simple, yet scientifically plausible opinion: humans seek God because our brains are biologically programmed to do so.

Researchers Newberg and D'Aquili used high-tech imaging devices to peer into the brains of meditating Buddhists and Franciscan nuns. As the data and brain photographs flowed in, the researchers began to find solid evidence that the mystical experiences of the subjects "were not the result of some fabrication, or simple wishful thinking, but were associated instead with a series of observable neurological events," explains Newberg. "In other words, mystical experience is biologically, observably, and scientifically real.... Gradually, we shaped a hypothesis that suggests that spiritual experience, at its very root, is intimately interwoven with human biology." Lay readers should be warned that although the topic is fascinating, the writing is geared toward scientific documentation that defends the authors' hypothesis. For a more palatable discussion, seek out Deepak Chopra's How to Know God, in which he also explores this fascinating evidence of spiritual hard-wiring. --Gail Hudson
