Allan Snyder, director of Centre for the Mind at the University of Sydney is using transcranial magnetic stimulation (TMS) to slow down or speed up various parts of the brain and by doing so appears to be able to unlock savant intellectual abilities dormant in many minds.
As remarkable as the cat-drawing lesson was, it was just a hint of Snyder's work and its implications for the study of cognition. He has used TMS dozens of times on university students, measuring its effect on their ability to draw, to proofread and to perform difficult mathematical functions like identifying prime numbers by sight. Hooked up to the machine, 40 percent of test subjects exhibited extraordinary, and newfound, mental skills. That Snyder was able to induce these remarkable feats in a controlled, repeatable experiment is more than just a great party trick; it's a breakthrough that may lead to a revolution in the way we understand the limits of our own intelligence -- and the functioning of the human brain in general.
