Brain signals from monkeys used to control robot legs via web link

London, Nov 28 (ANI): American scientists have devised a method by which brain signals from monkeys in North Carolina can be used to control a pair of robot legs in Japan via a web link.

The method is important as it holds hope for paralysed people to walk again via brain signals.

The study was conducted by a team of researchers at Duke University in Durham.

In the study, they implanted electrodes in the brains of two rhesus macaques and analysed the electrical signals that drive their legs.

Then, the scientists mapped the signals to specific leg movements and, via the Internet, used them to control a pair of robot legs at the Advanced Telecommunications Research Institute International in Kyoto, reports New Scientist.

The researchers hope that the technique will one day allow paralysed people to control prosthetic legs via brain implants.

The study was presented at Neuroscience 2007 in San Diego, California. (ANI)
