According to the results of a new experiment that were revealed recently, researchers have made progress in enabling a woman who suffered from paralysis of both arms and legs, to move her arm using brain-machine technology.

The technology was revealed recently at the annual conference of the American Association of Neurological Surgeons in New Orleans.  According to the researchers, the technology is based on a brain- machine interface which takes signals from the brain, and transmits the signal to the arm to enable movement.

Spinal injury lawyers have found that such brain- machine interface technologies are being widely used as part of prosthetics development, in order to enable people who have suffered paralysis of their arms and legs to move these limbs.  The technology is likely to benefit not just persons who have lost limbs, but also those who have lost the use of their arms due to paralysis after suffering a spinal cord injury or head and neck injuries.

In this technique, the person undergoes a surgery in which electrode grids are implanted into his brain.  The researchers acknowledge that this is a complicated surgery, because the electrodes penetrate the surface of the brain by as much as 1/16th of an inch.  The electrodes are connected to terminals that protrude from the person’s skull.

When the researchers connected the terminals to the computer, they found that when the woman thought of moving her arm, it fired a signal in the woman’s brain, allowing movement in her arm.

Over a period of time, the woman was able to not just perform simple physical movements, like moving her arm, but was also able to pick up and grasp objects, rotate her arm and wrist, and even feed herself chocolate.
