POWER OF THOUGHT

American scientist Peter Brunner of the Laboratory of Cognitive Sciences Wadsworth Center of Albany, New York, presents the Brain Computer Interface (BCI) system permitting totally paralysed persons to move a cursor on a computer screen or write a message exclusively with the power of thought on June 8, at the International Autonomic Salon-Paris 2006. The technology digitalises brain signals emitted as electrical impulses -- picked up by electrodes -- to convey intent. PHOTO: AFP
