A new study suggests that meditation may modulate brain waves called alpha rhythms, which help regulate the transmission of sensory input from the surrounding environment. Harvard researchers randomly assigned 12 healthy adults to an eight-week course of training in meditation-based stress reduction or to a control group whose participants did not meditate.

At regular intervals, researchers used an imaging technique called magnetoencephalography to measure electrical currents in an area of the brain that processes signals from the left hand. During the tests, each participant was asked to … Read more »
