Volunteers control game ‘by thought’

USING thought alone and with some electrodes placed on the surface of the brain, four volunteers were able to control a video game, US researchers reported yesterday.

Simply by thinking the word ‘move’, the volunteers played the simple video game, the researchers reported.

“We are using pure imagination. These people are not moving their limbs”, said Dr Eric Leuthardt, a neurosurgeon at Barnes- Jewish Hospital in St Louis, USA, who worked on the study.
