A team of US researchers has shown that controlling devices with the brain is a step closer.
Four people, two of them partly paralysed wheelchair users, successfully moved a computer cursor while wearing a cap with 64 electrodes.
Previous research has shown that monkeys can control a computer with electrodes implanted into their brain.
The New York team reported their findings in the Proceedings of the National Academy of Sciences.
“The results show that people can learn to use scalp-recorded electroencephalogram rhythms to control rapid and accurate movement of a cursor in two directions,” said Jonathan Wolpaw and Dennis McFarlane.
