Timewarp: How your brain creates the fourth dimension

Take the peculiar case of an individual known as BW. As BW drove his car one day, the trees and buildings by the road began to speed by, as if he were driving at 300 kilometres per hour. BW eased up on the accelerator, but the cityscape continued to whizz by. Unable to cope with the speed of the world around him, BW stopped his car by the roadside. While BW perceived the world as having accelerated, in reality what had happened was that BW had slowed down. He walked and talked in slow motion: when his doctor asked him to count 60 seconds in his head, he took 280 seconds to do it. It turned out that he had a tumour in his brain's frontal cortex.

In one experiment, healthy volunteers learned to play a video game in which they had to steer a plane around obstacles. Once people became used to the game, the researchers modified it to insert a 0.2-second delay in the plane's response to volunteers moving the computer mouse. -- But the subjects' strangest experience occurred then the experimenters removed the delay and set the timing back to normal. Suddenly, the players were perceiving the plane to be moving before they consciously steered it with the mouse (Psychological Science, vol 12, p 532). That's uncannily similar to how people with schizophrenia describe feelings that they are somehow being controlled by another being.
