...comes with almost everything you will need to begin enjoying it - a rechargeable battery, power cord, memory stick, earbuds with remote control, strap and case with chamois cloth - except for a game. The first million units even come with a copy of the movie Spider-Man 2 in Sony's new Universal Media Disc format. A plastic-encased 1.8GB-capacity digital disc the size of a chocolate chip cookie, UMDs are a PSP-only media source, carrying games, movies and possibly music, although no music UMDs are available at this time. There are no writable UMDs either...
...clock until midnight, a string of children files into the National Institutes of Health outside Washington to have their brains scanned. Giedd and his team ease the kids through the MRI procedure, and then he gives them a brain tour of their pictures--gently pointing out the spinal cord and the corpus callosum, before offering them a copy to take to show-and-tell...
Penny Rickhoff's world began to shrink suddenly in 1990, after a very tall and very heavy file cabinet toppled over onto her back. The freak accident damaged her spinal cord, leaving her with a constant, gnawing pressure in her lower back. "If I sit for very long, I'm in excruciating pain," she says. Once an avid tennis player, world traveler and amateur pilot, Rickhoff, who is in her 50s, was not only grounded, but she also became almost a prisoner in her home, unable to drive more than a short distance, unable to go anywhere without toting special...
...have it. Nasty though it is, pain plays a valuable role in our overall health. Doctors liken it to an alarm system for the body. When skin, cartilage, muscle or other tissue is injured, peripheral nerves in the area send a shrieking signal to the spinal cord and brain. The immediate result, usually processed in the spinal cord: you pull your hand away from the stove, you shift your weight off the broken bone, you sit down. All pain signals ultimately land in the brain, where they trigger thought ("That was dumb!"), emotions (tears, sobs), memories and a complex array...
With chronic pain, however, the alarm continues to shriek uselessly long after the physical danger has passed. Somewhere along the line--maybe near the initial injury, maybe in the spinal cord or brain--the alarm system has broken down. What researchers have only recently come to understand is that prolonged exposure to this screaming siren actually does its own damage. "Pain causes a fundamental rewiring of the nervous system," says Dr. Sean Mackey, director of research at Stanford University's Pain Management Center. "Each time we feel pain, there are changes that occur that tend to amplify our experience...
