Scientists have succeeded in developing the fine motor skills of the hand to mimic the required brain signals to catch a hersenimplantaat. Thus, such chips are becoming more precise.
For the study, conducted at the university in Zhejiang, was used to monkeys, which have a chip implanted got. This was located in a brain region that provides for the control of muscles. Then gave the monkeys a task where used was of the fingers, after which the in the brain-generated signals were captured by the chip. The implant sends its signals to a connected robotic hand, up. This then began in the same way as moving as that of the monkey itself.
The simulated movements are less precise than those of a real hand. That is because the chip only the signals of 200 neurons captures, while the fine motor skills of the hand by hundreds of thousands of neurons is controlled. Newer implants have more signals at the same time, might catch on and so the robot motion more precise.
Scientists are already involved with using breinimplantaten robotledematen to send. As succeeded already in to a man with the help of thoughts and a robotic arm to send. Gestures are more difficult to simulate because of the fine motor skills.
