Utne - Understanding the next evolution (Internet) 07/27/06 In the July/August issue of Science & Theology News (article not available online), Heather Wax describes rhythm's ability to affect brainwaves. Studies show that brain waves adjust to match tempo when participants listen to rhythms attentively, enabling music to regulate mental states much like medications do. An experiment at the University of Texas Medical Branch at Galveston found that regular sessions of rhythmic light and sound stimulation increased focus and IQ scores among boys with Attention Deficit Disorder and reduced behavioral problems. A University of Washington study showed that similar exposure increased the brain's blood flow and improved cognitive functioning in the elderly. Of course, many of us already use beats to alter our moods: A dose of techno can energize when deadlines loom and jazz can keep insanity at bay in the car with kids. The day may come, though, when we think of music as another drug -- administered aurally.
