A cripple man, who has no feeling in his limbs, with the help of a ge lwa mplanteerde chip a robotic arm can operate. The chip reads signals from the brain and translates it into movement of the robotic arm.
The chip showed the thirty years ‘ subject and direct movements in all three dimensions with the robotic arm. To read the brain signals, the chip on the surface of the brain is placed. This is remarkable because it is often necessary to electrodes deep in the brain. The advantage of this is that less complex operations are required to the chip on the brain, and there is less chance of rejection.
With the chip and the robotic arm once connected, did the subject manage to have a ball to grab and release it again. This seems to be the so-called brain-computer interface suitable for complex movements.
In the brain it reads the chip signals of groups of brain cells that together are the motorcortex forms, the hersencentrum that is responsible for movement. By the subject first, the operation of an arm in to images, could researchers via a brain scan to see which areas of the brain are turned on. Because of this, they got an idea about where the chip implanted had to be.
The research was primarily intended to determine whether the used chip in people for a month to work; because of safety regulations if the chip no longer be used. In experiments with monkeys were already chips used for artificial limbs to operate. Also hersenchips for use in humans are not new; years ago there was already a robotic arm via an implant operated, but this had to be the patient be on a computer to be connected.
