It can also be used to monitor my movements through each room inside. As I tour the offices of Face++ (pronounced “face plus plus”), located in a suburb of Beijing, I see it appear on several more screens, automatically captured from countless angles by the company’s software. On one screen a video shows the software tracking 83 different points on my face simultaneously.

It is possible to transfer money through Alipay, a mobile payment app used by more than 120 million people in China, using only your face as credentials. Meanwhile, Didi, China’s dominant ride-hailing company, uses the Face++ software to let passengers confirm that the person behind the wheel is a legitimate driver. (A “liveness” test, designed to prevent anyone from duping the system with a photo, requires people being scanned to move their head or speak while the app scans them.)</span></div> <div class="ooyala-player-container l-article-video" style="background-attachment: initial;

color: white;">The French neuroscientist was watching a macaque monkey as it hunched aggressively at one end of a treadmill. His team had used a blade to slice halfway through the animal’s spinal cord, paralyzing its right leg. Now Courtine wanted to prove he could get the monkey walking again. To do it, he and colleagues had installed a recording device beneath its skull, touching its motor cortex, and sutured a pad of flexible electrodes around the animal’s spinal cord, below the injury. A wireless connection joined the two electronic devices.</span></div> <div style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: millertext, serif; font-size: 19px; line-height: 1.63; margin-bottom: 30px; margin-top: -6px; max-width: 600px; outline: 0px; padding: 0px; vertical-align: baseline; width: 494.656px;"> <span style="background-color: black; color: white;">The result: a system that read the monkey’s intention to move and then transmitted it immediately in the form of bursts of electrical stimulation to its spine. Soon enough, the monkey’s right leg began to move. Extend and flex. Extend and flex. It hobbled forward. “The monkey was thinking, and then boom, it was walking,” recalls an exultant Courtine, a professor with Switzerland’s École Polytechnique Fédérale de Lausanne.</span></div> <br /> <figure class="l-magazine-promo" data-widget-layout="magazine-promo" data-widget-type="imageset" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border-top-color: rgb(0, 0, 0); border-top-style: solid; border-width: 4px 0px 0px; box-sizing: border-box; clear: none; float: none; margin: 20px 0px 30px; max-width: 600px; outline: 0px; padding: 30px 0px 0px; vertical-align: baseline; width: 494.656px;"><a class="magazine-promo-picture" href="https://www.technologyreview.com/magazine/2017/03/" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; box-sizing: border-box; display: inline-block; margin: 0px; padding: 0px; vertical-align: baseline;"><picture style="box-sizing: border-box; display: inline-block; position: relative; width: 180px;"><span style="background-color: black; color: white;"><img class="magazine-promo" src="https://cdn.technologyreview.com/i/images/ma17cover1spineshadow.jpg?sw=180" srcset="https://cdn.technologyreview.com/i/images/ma17cover1spineshadow.jpg?sw=180 1x,https://cdn.technologyreview.com/i/images/ma17cover1spineshadow.jpg?sw=360 2x" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-shadow: rgba(0, 0, 0, 0.27) 4px 4px 10px 1px; box-sizing: border-box; display: inline-block; line-height: 0; margin: 0px 0px 10px; max-width: 100%; outline: 0px; padding: 0px; vertical-align: middle; width: 180px;" /></span></picture></a><figcaption class="magazine-promo magazine-promo-cap" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; float: right; font-size: 15px; line-height: 1.4; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;"><div class="magazine-promo-cap__heading" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-size: 19px; font-weight: 700; margin: 0px; outline: 0px; padding: 0px 0px 13px; vertical-align: baseline; width: 284.656px;"> <span style="background-color: black; color: white;">This story is part of our March/April 2017 Issue</span></div> <a class="magazine-promo-cap__cta" href="https://www.technologyreview.com/magazine/2017/03/" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; box-sizing: border-box; display: block; font-size: 18px; font-weight: 700; margin: 0px; padding: 0px; position: relative; vertical-align: baseline; width: auto;"><span style="background-color: black; color: white;">See the rest of the issue</span></a><span style="background-color: black; color: white;"><br style="box-sizing: border-box;" /></span><a class="magazine-promo-cap__cta" href="https://www.technologyreview.com/subscribe/" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; box-sizing: border-box; display: block; font-size: 18px; font-weight: 700; margin: 0px; padding: 0px; position: relative; vertical-align: baseline; width: auto;"><span style="background-color: black; color: white;">Subscribe</span></a></figcaption></figure><br /> <div style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: millertext, serif; font-size: 19px; line-height: 1.63; margin-bottom: 30px; margin-top: -6px; max-width: 600px; outline: 0px; padding: 0px; vertical-align: baseline; width: 494.656px;"> <span style="background-color: black; color: white;">In recent years, lab animals and a few people have controlled computer cursors or robotic arms with their thoughts, thanks to a brain implant wired to machines. Now researchers are taking a significant next step toward reversing paralysis once and for all. They are wirelessly connecting the brain-reading technology directly to electrical stimulators on the body, creating what Courtine calls a “neural bypass” so that people’s thoughts can again move their limbs. </span></div> <div class="ooyala-player-container l-article-video" style="background-attachment: initial;

Besides treating paralysis, scientists hope to use so-called neural prosthetics to reverse blindness with chips placed in the eye, and maybe restore memories lost to Alzheimer’s disease (see “10 Breakthrough Technologies 2013: <a href="https://www.technologyreview.com/s/513681/memory-implants/" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; box-sizing: border-box; margin: 0px; padding: 0px; vertical-align: baseline;" target="_blank">Memory Implants</a>”).</span></div> <div style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: millertext, serif; font-size: 19px; line-height: 1.63; margin-bottom: 30px; margin-top: -6px; max-width: 600px; outline: 0px; padding: 0px; vertical-align: baseline; width: 494.656px;"> <span style="background-color: black; color: white;">And they know it could work. Consider cochlear implants, which use a microphone to relay signals directly to the auditory nerve, routing around non-working parts of the inner ear. Videos of wide-eyed deaf children hearing their mothers for the first time go viral on the Internet every month. More than 250,000 cases of deafness have been treated.</span></div> <br /> <figure class="l-article-img l-article-img--text-col" data-widget-layout="text-col" data-widget-type="imageset" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; clear: none; margin: 0px 0px 30px; max-width: 600px; outline: 0px; padding: 0px; vertical-align: baseline; width: 494.656px;"><span style="background-color: black; color: white;"><picture class="video-wrapper" style="box-sizing: border-box; display: inline-block; padding: 0px; position: relative; width: 494.656px;"></picture></span><figcaption class="article-cap article-cap--text-col" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-size: 15px; line-height: 1.4; margin: 0px; outline: 0px; padding: 10px 0px 0px; vertical-align: baseline; width: 494.656px;"><span style="background-color: black; color: white;">In this video made by EPFL researchers, a monkey with a spinal cord injury that paralyzed its right leg is able to walk again.</span></figcaption></figure><br /> <div style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: millertext, serif; font-size: 19px; line-height: 1.63; margin-bottom: 30px; margin-top: -6px; max-width: 600px; outline: 0px; padding: 0px; vertical-align: baseline; width: 494.656px;"> <span style="background-color: black; color: white;">But it’s been harder to turn neural prosthetics into something that helps paralyzed people.

The technology remains too radical and too complex to get out of the lab. “Twenty years of work and nothing in the clinic!” Courtine exclaims, brushing his hair back. “We keep pushing the limits, but it is an important question if this entire field will ever have a product.”</span></div> <div style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: millertext, serif; font-size: 19px; line-height: 1.63; margin-bottom: 30px; margin-top: -6px; max-width: 600px; outline: 0px; padding: 0px; vertical-align: baseline; width: 494.656px;"> <span class="s1" style="background-attachment: initial; background-clip: initial; background-color: black; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; color: white; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">Courtine’s laboratory is located in a vertiginous glass-and-steel building in Geneva that also houses a $100 million center that the Swiss billionaire Hansjörg Wyss funded specifically to solve the remaining technical obstacles to neurotechnologies like the spinal cord bypass.

He is now trying to assemble in one place the enormous technical resources and talent—skilled neuroscientists, technologists, clinicians—needed to create commercially viable systems.</span></div> <div style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: millertext, serif; font-size: 19px; line-height: 1.63; margin-bottom: 30px; margin-top: -6px; max-width: 600px; outline: 0px; padding: 0px; vertical-align: baseline; width: 494.656px;"> <span style="background-color: black; color: white;">Among Donoghue’s top priorities is a “neurocomm,” an ultra-compact wireless device that can collect data from the brain at Internet speed. “A radio inside your head,” Donoghue calls it, and “the most sophisticated brain communicator in the world.” The matchbox-size prototypes are made of biocompatible titanium with a sapphire window. Courtine used an earlier, bulkier version in his monkey tests.</span></div> <div style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: millertext, serif; font-size: 19px; line-height: 1.63; margin-bottom: 30px; margin-top: -6px; max-width: 600px; outline: 0px; padding: 0px; vertical-align: baseline; width: 494.656px;"> <span style="background-color: black; color: white;">As complex as they are, and as slow as progress has been, neural bypasses are worth pursuing because patients desire them, Donoghue says. “Ask someone if they would like to move their own arm,” he says. “People would prefer to be restored to their everyday self. They want to be reanimated.”</span></div> <br /> <figure class="l-article-img l-article-img--8col" data-widget-layout="8col" data-widget-type="imageset" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; clear: both; float: left; margin: 0px 0px 30px -100px; outline: 0px; padding: 0px; vertical-align: baseline; width: 848px;"><picture style="box-sizing: border-box; display: inline-block; position: relative; width: 848px;"><span style="background-color: black; color: white;"><source media="(min-width: 1024px)" srcset="https://cdn.technologyreview.com/i/images/ma17-10-reversing5.jpg?sw=1080&cx=7&cy=229&cw=2104&ch=1183 1x,https://cdn.technologyreview.com/i/images/ma17-10-reversing5.jpg?sw=2160&cx=7&cy=229&cw=2104&ch=1183 2x" style="box-sizing: border-box;"></source><source media="(min-width: 850px)" srcset="https://cdn.technologyreview.com/i/images/ma17-10-reversing5.jpg?sw=1024&cx=7&cy=229&cw=2104&ch=1183 1x,https://cdn.technologyreview.com/i/images/ma17-10-reversing5.jpg?sw=2048&cx=7&cy=229&cw=2104&ch=1183 2x" style="box-sizing: border-box;"></source><source media="(min-width: 550px)" srcset="https://cdn.technologyreview.com/i/images/ma17-10-reversing5.jpg?sw=850&cx=7&cy=229&cw=2104&ch=1183 1x,https://cdn.technologyreview.com/i/images/ma17-10-reversing5.jpg?sw=1700&cx=7&cy=229&cw=2104&ch=1183 2x" style="box-sizing: border-box;"></source><source media="(min-width: 401px)" srcset="https://cdn.technologyreview.com/i/images/ma17-10-reversing5.jpg?sw=550&cx=7&cy=229&cw=2104&ch=1183 1x,https://cdn.technologyreview.com/i/images/ma17-10-reversing5.jpg?sw=1100&cx=7&cy=229&cw=2104&ch=1183 2x" style="box-sizing: border-box;"></source><source media="(min-width: 0px)" srcset="https://cdn.technologyreview.com/i/images/ma17-10-reversing5.jpg?sw=401&cx=7&cy=229&cw=2104&ch=1183 1x,https://cdn.technologyreview.com/i/images/ma17-10-reversing5.jpg?sw=802&cx=7&cy=229&cw=2104&ch=1183 2x" style="box-sizing: border-box;"></source><img class="article-img article-img--8col" src="https://cdn.technologyreview.com/i/images/ma17-10-reversing5.jpg?sw=1080&cx=7&cy=229&cw=2104&ch=1183" srcset="https://cdn.technologyreview.com/i/images/ma17-10-reversing5.jpg?sw=1080&cx=7&cy=229&cw=2104&ch=1183 1x,https://cdn.technologyreview.com/i/images/ma17-10-reversing5.jpg?sw=2160&cx=7&cy=229&cw=2104&ch=1183 2x" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; display: block; line-height: 0; margin: 0px; max-width: 100%; outline: 0px; padding: 0px; vertical-align: middle; width: 848px;" /><div class="article-enlarge" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;"> </div> </span></picture><figcaption class="article-cap article-cap--8col" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-size: 15px; line-height: 1.4; margin: 0px; outline: 0px; padding: 10px 0px 0px; vertical-align: baseline; width: 212px;"><span style="background-color: black; color: white;">A model of a wireless neurocommunication device sits on a skull.</span></figcaption></figure><br /> <div class="callout--tagged-event-promo" desc="in-story-promo-mittr-subscribe" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border-bottom-color: rgb(0, 0, 0); border-bottom-style: solid; border-top-color: rgb(0, 0, 0); border-top-style: solid; border-width: 4px 0px; box-sizing: border-box; margin: 0px; max-width: 600px; outline: 0px; padding: 20px 0px; vertical-align: baseline; width: 494.656px;"> <div class="callout__copy" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-size: 26px; font-weight: 700; line-height: 1.2; outline: 0px; padding: 0px; vertical-align: baseline;"> <span style="background-color: black; color: white;">Become an MIT Technology Review Insider for in-depth analysis and unparalleled perspective.</span></div> </div> </div> </div>
