Monkey learns to master robotic arm with brain impulses
Summary from multiple countries, from articles in English
|
Monkeys have learnt to feed themselves using a robotic arm controlled by their thoughts, in an experiment that could ultimately help paralysed people and amputees to lead more independent lives. (article 3)
The success is by far the best demonstration yet of a technology that promises to transform the quality of life of patients paralysed by spinal injuries, strokes or wasting conditions such as motor neuron disease. (article 3)
Scientists expect that technology will eventually allow people with spinal cord injuries and other paralyzing conditions to gain more control over their lives. (article 1)
Schwartz said the technology behind this feat may lead to brain-powered prosthetic limbs for people with spinal cord injuries or disabling diseases that make such simple tasks impossible. (article 4)
Schwartz team picks up those signals through an array of microelectrodes half the size of a thumbtack that has been implanted in the monkey's brain. (article 4)
Small probes, the width of a human hair, were inserted into the monkeys' primary motor cortex - the region of the brain that controls movement. (article 2)
After some training, two monkeys - who had had their own arms restrained - were able to use the prosthetic limbs to feed themselves with marshmallows and chunks of fruit. (article 2)
