Researchers have developed a monkey's brain that may eventually be used on a machine that allows spinal cord injury to control an interface between the arms or legs. Initially, researchers at the Neuroengineering Center at Duke University in Durham, North Carolina, developed an interface that could control a prosthesis. Now, scientists have developed an interface that allows Rhesus macaques to move their two arms and at the same time they look at their image on a computer screen. From a third-person perspective, the virtual monkey head is shown as a real-time decoding of the two arms of the movement from the rhesus monkey's brain. In the experiment, virtual machines and three-dimensional target objects from the first person's point of view appear on the screen. The professor of neurobiology said that for the first time he learned the monkey's head control of a pair of joysticks, but then he trained and remained completely still. "They're training," Nicolelli said. "Don't move their weapons, they train just imaginative changes. And we get signals that the two parts of their brains are routed to computers running computer conversion algorithms. They Voluntary will enter a virtual body movement." Two monkeys involved in exercise behavior, planning from multiple regions of their brain's two hemispheres, the researchers measured the activity of 500 neurons. Nikolelis said that this nerve activity is much more involved than moving each arm alone. As monkeys become better at using their brains. The researchers found that the plasticity of the brain or the growth of neurons, signs of possible signs, monkeys turn virtual weapons into their own psychological image. Nikolelis said that scientists are currently developing a brain-controlled nerve prosthetic vest to allow the wearer to control the prosthetic device. The device is converted into motion instructions, inside the vest, and a machine can read the final digital signal from the brain's electrical signal. Nikolelis stated that it will use the waistcoat of the upcoming 2014 World Cup. “We want to make a demonstration. At the opening ceremony, there was a young, paraplegic Brazilian young man walking into the field using this vest, wearing this vest, controlling his brain activity, and being responsible for kick-off the World Cup.†He said . Vests can help people with spinal cord injuries and some diseases caused by paralysis. Industrial large fans often have diameters of several meters, weights of tens or even hundreds of kilograms, and are suspended for installation and rotation. It is necessary to consider various aspects such as speed, material, noise, and energy consumption. The safety of industrial large fans is closely related to the material of their blades and the structure of the entire machine, and there are strict requirements for material strength and toughness.
