Mind over matter lets there be light with brainwaves; Use your head: Scientists prove the power of thought.
Harriet Wood, of the Science Museum, London, demonstrates a mind switch as part of Brain Awareness Week at the museum yesterday.
Using the latest scientific technology from Australia, a person can be linked up to a set of wires which record alpha, beta, and theta waves in the brain.
The alpha waves, known as the good waves - prominent when a person is relaxing - are what triggers the switch.
When a person closes their eyes, the alpha rays increase and the greater amplitude provides enough energy to turn on the light.
The process is very different from telekinesis, where the brain does not use technology to move things and relies on near-supernatural causes.
Prof Ashley Craig, aged 46, from the University of Technology in Sydney, has been working on the project with a team of ten scientists since 1996.
He said: 'We are the only team in the world to be focusing on the alpha waves so intensely and the only team to have carried out field trials.
'There are huge possibilities for disabled people, people suffering from polio, quadriplegia and those who are elderly and wheelchair-bound.'
The system enabled a person to turn a television on and off and change the volume.
Prof Craig continued: 'With training, this will be a very powerful form of control. It also has potential for children because they have more alpha waves than adults.'
Beta waves are very-high frequency and are used when a person concentrates. Theta waves are very-low frequency and are related to tiredness.
