Allan Snyder, a scientist at the University of Sydney, has found that during transcranial magnetic stimulation people exhibit savant-like intelligence (requires registration).
There are four drawings at the top of the page drawn by a research subject who was asked to draw a picture of a dog before, during and after the TMS. As you can see, the quality of the drawing improved dramatically. I’m sure it will take years of research to learn more about the process, but it’s exciting to think what you could do with a turbo boost of intelligence every now and then.
Of course, it’s not just for artists. Snyder tested it “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.”
