I AM ALIVE AND I AM A NORMAL PERSON (OR SORT OF..LOL)
sameolddani: mmmmmmmmmm, no commets (lol). .. and what you expect you have it . lolita_lempicka: I agree, our mind is very powerful, see this news: "With the power of the mind, researchers manage to reverse paralysis in monkeys, making a bridge from the brain to muscle" Thursday October 16, 2008 | Published in print LONDRES (New Scientist).– The people paralyzed by nerve damage may someday help brain implants able to search and detect the activity of a single neuron. In an experiment in monkeys that had been temporarily paralyzed with anesthetic, these implants restored muscle control. A spinal cord trauma or stroke can cause paralysis by blocking signals from the motor cortex to the muscles they control. Despite the trauma, motor neurons are active, and experiments in monkeys showed that it is possible to decode the signals generated by a bunch of neurons and use them to control computer cursors and robotic arms. Unfortunately, the algorithms required to decode and development have required considerable computing power. Now physiologist Chet Moritz and colleagues at the National Center for Primate Research in Seattle developed a technique that could allow people to regain control of its own members, without the need for complex decoding algorithms. El trabajo se publica en la edición electrónica de la revista Nature (DOI: 10.1038/nature07418). The work is published in the online edition of the journal Nature (DOI: 10.1038/nature07418). The idea was to tap individual motor cortex neurons, rather than groups, and send control signals directly to muscles. To test this idea, two macaques were implanted 12 electrodes of 50 microns thick that they could move independently. Then anesthetized the nerves controlling the movements of his wrists and sent signals to electrodes attached directly to the muscles. Despite the nerve block, the monkeys were able to tighten these muscles when trying to reach a tasty reward. "These results are the first demonstration that artificial connections between cortical cells and muscles can compensate for interrupted physiological functions and restore control of paralyzed limbs, they say, Chet Moritz and colleagues in Nature. Future developments in this strategy of direct control can lead to implantable devices that help restore the deliberate movements in individuals who suffer paralysis.
