...physical manipulations. Electrical stimulation of the brain during surgery can cause a person to have hallucinations that are indistinguishable from reality, such as a song playing in the room or a childhood birthday party. Chemicals that affect the brain, from caffeine and alcohol to Prozac and LSD, can profoundly alter how people think, feel and see. Surgery that severs the corpus callosum, separating the two hemispheres (a treatment for epilepsy), spawns two consciousnesses within the same skull, as if the soul could be cleaved in two with a knife...
...first discoveries of neuroplasticity came from studies of how changes in the messages the brain receives through the senses can alter its structure and function. When no transmissions arrive from the eyes in someone who has been blind from a young age, for instance, the visual cortex can learn to hear or feel or even support verbal memory. When signals from the skin or muscles bombard the motor cortex or the somatosensory cortex (which processes touch), the brain expands the area that is wired to move, say, the fingers. In this sense, the very structure of our brain--the relative...
When the scientists compared the TMS data on the two groups--those who actually tickled the ivories and those who only imagined doing so--they glimpsed a revolutionary idea about the brain: the ability of mere thought to alter the physical structure and function of our gray matter. For what the TMS revealed was that the region of motor cortex that controls the piano-playing fingers also expanded in the brains of volunteers who imagined playing the music--just as it had in those who actually played...
...would be making a decision about running soon. Despite his low Q-rating, Tancredo presents the bigger of the two dark-horse threats. His signature issue - immigration reform - makes for the kind of sound-bite-friendly courting of the primary base and handsome visuals (miniature fence, anyone?) that can alter the terms of debate. And that's all Tancredo's really trying to do. If nothing else, he'll make life a little harder for John ("I'll build the goddamned fence if they want it") McCain...
...feel he could even implicitly endorse a gay marriage ban and would rather resign than pretend. But what happens if you let officials take office with an asterisk in their oath? That would "come perilously close to saying [that] in their duties they will ignore the law or alter the law when it conflicts with their personal principles," UW-Madison political science professor Howard Schweber told the Wisconsin State Journal. "That is a fundamental breach of the duty of office...
