In an experiment straight out of a comic book, Virginia Tech scientists have found a way to improve sensory abilities. All it takes is a detailed map of the brain, an ultrasound gun, and a willing patient. What could go wrong?
The experiment was simple enough. The Virginia Tech team directed ultrasound waves at a particular part of the cerebral cortex and then tested subjects’ sensory abilities with two tests: one that asked them to distinguish between two different pin pricks and another to determine the difference between puffs of air. Much to their surprise, the ultrasound improved the subjects’ performance at both tests. When the ultrasound waves targeted the brain at a slightly different location, the improvement disappeared.
