...psychiatry at Harvard Medical School who worked with Benson, recorded EEGs of one group of subjects taught to meditate and another given books on tape with which to chill out. Over the next few months, the meditators produced far more theta waves than the book listeners, essentially deactivating the frontal areas of the brain that receive and process sensory information. They also managed to lower activity in the parietal lobe, a section of the brain located near the top of the head that orients you in space and time. By shutting down the parietal lobe, you can lose your sense...
What scientists are discovering through these studies is that with enough practice, the neurons in the brain will adapt themselves to direct activity in that frontal, concentration-oriented area of the brain. It's what samurais and kamikaze pilots are trained to do and what Phil Jackson preaches: to learn to be totally aware of the moment. "Meditation is like gasoline," says Robert Thurman, director of the Tibet House (and father of actress Uma Thurman). "In Asia meditation was a sort of a natural tool anyone could use. We should detach it from just being Buddhist...

Neuroscientists have used fMRI to identify three areas of the left side of the brain that play key roles in reading. Scientifically, these are known as the left inferior frontal gyrus, the left parieto-temporal area and the left occipito-temporal area. But for our purposes, it's more helpful to think of them as the "phoneme producer," the "word analyzer" and the "automatic detector." We'll describe these regions in the order in which they are activated, but you'll get closer to the truth if you think of them as working simultaneously, like the sections of an orchestra...
