Shara shares this story from Medium's new school website, OneZero regarding Second Sight's experimental brain implant that provides a sort of artificial vision:
From the skin, the Orion feels like a try of eyeglasses with a little camera and video process unit connected thereto. ingrained within the brain, however, maybe a postage-stamp-sized chip containing sixty electrodes that sits on the cortical region, the part of the brain that processes visual data. once the device is switched on, the camera captures an individual's surroundings, and therefore the wireless video process unit converts those pictures into electrical pulses victimization associate degree algorithmic program. Those pulses square measure transmitted to the electrodes on the brain, that interprets them as visual clues... The Orion, that shares abundant of its technology with the Argus II, bypasses the attention and nervus opticus utterly. "With this system, we're testing, you do not even ought to have eyes for the device to figure," says Dr Nader Pouratian, the surgeon at Ronald Reagan UCLA middle World Health Organization ingrained mythical being Esterhuizen's device. because the primary investigator of the trial at UCLA, he has outfitted four patients with the device. the opposite 2 study participants received the implant from Dr Daniel Yoshor at Baylor faculty of drugs in Houston, Texas...
Esterhuizen and therefore the different participants have regained a restricted quantity of vision once being utterly blind for years or decades. whereas they do not see colour, shapes, or clear edges and cannot nevertheless browse text, they're ready to distinguish lightweight from dark, they'll acknowledge moving objects, and that they have a point of depth perception. folks and objects seem as dots of sunshine appreciate wherever they are placed, and as they meet up with, a lot of dots seem. "It's like learning a replacement language," Esterhuizen says. "You learn the way to interpret what is going on on..."
Electrodes within the brain additionally cause connective tissue to create over time, creating them finish off, thus it's not clear however long these implants can last. Jessy Dorn, vice chairman of clinical and scientific affairs at ESP, says the electrodes employed in the Orion device ought to work for a minimum of 5 years. meaning patients can in all probability eventually lose what very little vision they acquire with the devices. Another major limitation of the Orion is that it's solely helpful for those that were born sharp-sighted and later lost their vision. In folks that square measure born blind, the elements of the brain that square measure liable for sight aren't absolutely developed, and visual data can not be effectively transmitted to the brain. a tool that would facilitate all folks with cecity remains an extended method off... Esterhuizen although is hopeful regarding the longer term of helpful technologies for the blind and visually impaired. "It's simple baby steps for currently," he says. "But eventually I believe this technology can modification the lives of immeasurable folks."
