A better, more realistic scenario would be for some interesting cross-wiring going on in the brain like the human calculator guy that can do very complex calculations faster than people can punch them into a calculator. The part of his brain that does math was cross-wired with parts of the brain that are responsible for movement.

Quote:Tests via a MRI scan, whilst on Stan Lees Super Human Show revealed that when he is calculating numbers a different area of his brain is being used – the part that is normally associated with movement (close to the motor cortex).
