The blind can see

The blind can seeThe blind can see American scientists have developed responsive to light of a computer chip that could be implanted in the eyes of the blind people, resulting vision will be partially restored. The goal of scientists is to allow people suffering from some form of blindness (e.g., senile degeneration of the cornea) to see 1000 light points with 1000 tiny electrodes placed in the retina. Some diseases that lead to blindness, eye damage cells that turn light into electrical impulses. However, the "path" to the brain, by which these impulses are transmitted, remain intact. The researchers hope that by using the invented chip will be able to send signals to the brain, necessary for the partial recovery of vision. "Our goal is to make it so that blind people could read, walk around the house without bumping into objects, and to perform basic household chores," says project Manager Kurt Wessendorf (Sandia National Laboratories, USA). "They will not be able to drive a car - at least in the near future, because instead of millions of pixels (as normal seers people) they will see about a thousand," says the scientist. - The image will come to their eyes a little slow and will have a yellowish tinge. But the main point is that the blind can see". The idea is to use a tiny camera and transmitter mounted in a frame for glasses, for the transmission of information and energy in chips implanted in the eyeball. The chips will be connected to the nerve endings of the cells of the retina, which sends electrical impulses to the brain, where the resulting image. "We believe that blindness is a serious problem," says Dean Cole of the Department of biological research, U.S. Department of energy, and the use of alloy modern micro - and nanotechnologies and materials opens new opportunities for scientists in those areas where previously they were met with a blank wall". "Of course, compared to the design proposed by nature, what we do, looks very rough," said Kurt Wessendorf. While scientists have learned how to stimulate nerve endings in large groups of nerves. However, in the future they hope will be able to do this for each separate nerve. The project will last for five years. Scientists start with a device integrated into a frame of spectacles, to then move to the implantation of all components in the cornea of the eye. If all goes well, we plan to prepare for surgery the first five people. Source: Bi-bi-si.
