Meditation practice to train the brain

Scientists Bridle at Lecture Plan for Dalai Lama from NYTimes

"He has been an enthusiastic collaborator in research on whether the intense meditation practiced by Buddhist monks can train the brain to generate compassion and positive thoughts. Next month in Washington, the Dalai Lama is scheduled to speak about the research at the annual meeting of the Society for Neuroscience.
But 544 brain researchers have signed a petition urging the society to cancel the lecture, because, according to the petition, "it will highlight a subject with largely unsubstantiated claims and compromised scientific rigor and objectivity."
Defenders of the Dalai Lama's appearance say that the motivation of many protesters is political, because many are Chinese or of Chinese descent. The Dalai Lama fled Tibet in 1959 after the Chinese crushed a Tibetan bid for independence."
