Initial results detected promising neuron spikes or nerve impulses and the patient is recovering well, he said.The company’s goal is to connect human brains to computers and it says it wants to help tackle complex neurological conditions.A number of rival companies have already implanted similar devices. BBC News has approached both Neuralink and the US’s medical regulator, the Food and Drug Administration (FDA), for comment.Mr Musk’s company was given permission to test the chip on humans by the FDA in May, a critical milestone after earlier struggles to gain approval.This gave the green light for the start of the six-year study during which a robot is being used to surgically place 64 flexible threads, thinner than a human hair, on to a part of the brain that controls “movement intention”, according to Neuralink.The company says that these threads allow its experimental implant – powered by a battery that can be charged wirelessly – to record and transmit brain signals wirelessly to an app that decodes how the person intends to move.Posting on X, the social media platform he owns which was formerly known as Twitter, Mr Musk said Neuralink’s first product would be called Telepathy.Telepathy, he said, would enable “control of your phone or computer, and through them almost any device, just by thinking”. “Initial users will be those who have lost the use of their limbs,” he continued. Referring to the late British scientist who had motor neurone disease, he added: “Imagine if Stephen Hawking could communicate faster than a speed typist or auctioneer. That is the goal.”While Mr Musk’s involvement raises the profile of Neuralink, he faces rivals, some of who have a track record dating back two decades. Utah-based Blackrock Neurotech implanted its first of many brain-computer interfaces in 2004.Precision Neuroscience, formed by a Neuralink co-founder, also aims to help people with paralysis. And its implant resembles a very thin piece of tape that sits on the surface of the brain and can be implanted via a “cranial micro-slit”, which it says is a much simpler procedure.Existing devices have also generated results. In two separate recent US scientific studies, implants were used to monitor brain activity when a person tried to speak, which could then be decoded to help them communicate.More on this storyWhy is Elon Musk’s brain chip firm Neuralink in the news?Published26 May 2023

This day has been hard-won and we need to cherish and protect it, and welcome back the Shanghai we are familiar with and missed.”E-commerce professional Chen Ying was planning to work from home after the lockdown was eased, but she told AFP news agency she might treat her two-year-old son to a long-awaited walk outside.”We should have been free to begin with, so don’t expect me to be deeply grateful now they’ve given it back to us,” she added.This video can not be playedTo play this video you need to enable JavaScript in your browser.Lockdown has seen many residents lose income, struggle to find enough food and cope mentally with prolonged isolation.Manufacturers including Western car makers Volkswagen and Tesla have been particularly impacted by the restrictions as staff were kept away from factories or had to work in “closed loop” conditions, where they lived at the plants.On Wednesday a basic service will resume on public transport and shops will open with larger ones operating at 75% capacity, but cinemas, museums and gyms will remain closed.Most children will not return to face-to-face schooling.There are new rules too:All residents will be required to show a green health code on their smartphone to leave their home compounds or buildings and access most placesAll residents wishing to move around the city on public transport and access banks, malls etc will be required to have a negative PCR test certificate valid in the last 72 hoursAnd restrictions on leaving Shanghai remain, with any resident travelling to another city facing quarantine of 7-14 days on arrival.The city has a 50-point plan aimed at revitalising its economy, which before the lockdown was worth more than $600bn (£475bn).New measures include reducing some taxes for car buyers, speeding up the issuance of local government bonds and fast-tracking approvals of building projects.Big bang for ShanghaiIt was supposed to last just nine days. A staggered lockdown to lessen the impact on the city’s economy, state media said. It lasted 65 days. It crippled Shanghai and scarred its people.The easing of restrictions is happening as quickly as they were imposed. There’s no gradual process, over several weeks. Instead there’s a big bang: one day when most of the emergency rules and regulations are simply being lifted.The relief is immense, for generations of some families who’ve lived together behind a locked front door for more than two months. For workers who’ve lived in tents inside factories where they’ve carried on working. For the shop and restaurant owners whose livelihood ground to a halt. For the thousands of people forced to leave their homes and sent to quarantine centres. For the almost 25 million people who live here.The rigidity of the lockdown caused much frustration in the city.Marketing professional Anita Xu, 32, felt “a little caught unawares”. “Even if you can go out, I don’t know what you can do,” she told AFP.But Todd Pearson, managing director of Camel Hospitality Group, which operates restaurants, bars and gyms in and around Shanghai, sounded a cautious note when he spoke to Reuters news agency.”I’m hopeful that they will rush things along to restart the economy,” he said. “I just hope it’s not at the cost of more outbreaks. I’m not sure many businesses or the people could handle much more.”China has registered at least 14,604 deaths and 2,426,568 cases of Covid during the pandemic, with nearly 90% of its population fully vaccinated.Worldwide, Covid has killed at least 6,289,241 people, according to John Hopkins University research.More on this storyShanghai to lift curbs on businessesEntire community relocated over CovidThe hard life of a homeless Shanghai deliverymanResidents ‘running out of food’
