Scientists develop “artificial nervous”
Scientists are studying the United States to create “artificial nerve” so that people who installed prosthesis can feel the heat of the coffee cup and touch other people’s feelings at the same time, the kinds of nerve cells can also promote new growth.
University of Michigan plastic surgeon Paul Cederna led the team carried out experiments in mice. They will Pedot (Poly stays dioxy thiophene, a new type of organic light-emitting conductive material, the efficiency of electrical signals transmitted 10 times that of metal, but it also can promote new cell growth) fragments connected with the nerve cells, creating a the “artificial nervous” that allows the muscles of mice necrosis revitalized.
In the first experiment, the orthopedic doctor will Pedot grafted leg injury in mice. Subsequently, the new nerve fibers grow out, and “take over” the damaged nerve fibers, so that has been restored necrosis of muscle activity.
In the second experiment, the researchers created a “cup”, which contains the cell, muscle, Pedot substances and rat nerve, and then the “cup” grafted leg injury in rats. 114 days, began to generate new blood vessels and muscle, nerve fibers to re-grow, and, feeling animals, have been resumed.
Cederna hope that three years, experiments on humans in 10 years to create the first one has “artificial neural” artificial arm. These “artificial nerve” will work with prostheses attached to the sensors on the microchip can be the same as the natural transmission of neural signals the brain to achieve prosthetic two-way communication with the brain, so that people who installed prosthetic distinguish hot and cold, and have sense of touch.
However, the British Royal National Orthopedic Hospital, Michael Fox said, to create “a feeling” under the guise of the existence of enormous technological obstacles, the brain is likely to receive the wrong signal.
