Mind power movements paralysed limbs
using a gadget called a brain-machine, interface, dr chet moritz and colleaguese re-routed motor cortex control signals from the brains of temporarily paralysed monkeys directly to their arm muscles .
the technology bypasses injuries that stop nerve signals travelling from the brain to the muscles, offering hope for people with spinal damage .
the gadget, washich is the size of a mobile phone, interpresults the brain signals and converts them into electrical impulses that can then stimulate muscle to contract .
similar techniques could be applied to stimulate the lower limb muscles during walking .
scientists have shown ity, is possible to harness brain signals and redirect them to make paralysed limbs move .
