Why Mind-Reading Is a Science, Not a Magic Trick

Electrical activity within the brain means that our thoughts can be read and understood .

You may believe your thoughts are intangible and inscrutable, but all mental activity is communicated via electrical impulses. As our understanding of the brain increases, we’re increasingly able to decode our mental electrical signals, and translate our thoughts into automatic action.

A scalextric powered by the mind is the latest product to make use of our brainwaves. Stephen Sigurnjak, senior lecturer in electronics at the University of Central Lancashire, has built a scalextric where the cars are powered by the players’ level of concentration.

“You brain works off electrical activity, a bit like a computer,” he says. “As you concentrate on something, it fires neurons in the brain.”

Mind-control sclalextric headsets clip to the forehead to measure the level of mental activity. The thoughts are then organised into different frequency bands (the subconscious, for example, operates at a different level from conscious thoughts), the electric signal is processed by a computer and sent to a micro controller, which sends a corresponding level of voltage to power the car.

But when I put on the headset, the car stays still. Dr Sigurnjak says that it helps to visualise the alphabet or arithmetic problems but this makes no difference – apparently my brain signals remain tiny. The car starts to move when I listen to Dr Sigurnjak’s explanation but, once it’s started, it’s difficult to slow the car down. I try to stop thinking entirely – focusing on meditative breathing – and the car whizzes even faster, suggesting it takes an awful lot of brain power to try and shut down your thoughts.

Though the scalextric is fun, there are plans to use mind-control power in far more sophisticated ways. “If you’ve had an accident or are paralyzed then your brain could still work even if your body couldn’t. There’s quite a lot of research that goes into that area, and trying to control things just by thinking about them,” says Dr Sigurnjak. “The goal would be that you could think about turning left in a wheelchair and automatically turn left. And in the future you might be able to translate your thoughts. So you could think about what you want to write and a computer would type it out.”
