Musk's company aims to soon test brain implant in people
San Francisco (AP): Tech billionaire Elon Musk said his Neuralink company is seeking permission to test its brain implant in people soon.
In a "show and tell" presentation livestreamed on Wednesday night, Musk said his team is in the process of asking US regulators to allow them to test the device.
He said he thinks the company should be able to put the implant in a human brain as part of a clinical trial in about six months, though that timeline is far from certain.
Musk's Neuralink is one of many groups working on linking brains to computers, efforts aimed at helping treat brain disorders, overcoming brain injuries and other applications.
The field dates back to the 1960s, said Rajesh Rao, co-director of the Center for Neurotechnology at the University of Washington. "But it really took off in the 90s. And more recently we've seen lots of advances, especially in the area of communication brain computer interfaces."
Rao, who watched Musk's presentation online, said he doesn't think Neuralink is ahead of the pack in terms of brain-computer interface achievements. "But ... they are quite ahead in terms of the actual hardware in the devices," he said.
The Neuralink device is about the size of a large coin and is designed to be implanted in the skull, with ultra-thin wires going directly into the brain. Musk said the first two applications in people would be restoring vision and helping people with little or no ability to operate their muscles rapidly use digital devices.
He said he also envisions that in someone with a broken neck, signals from the brain could be bridged to Neuralink devices in the spinal cord.
"We're confident there are no physical limitations to enabling full body functionality," said Musk, who recently took over Twitter and is the CEO of Tesla and SpaceX.
In experiments by other teams, implanted sensors have let paralyzed people use brain signals to operate computers and move robotic arms. In a 2018 study in the journal PLOS ONE, three participants with paralysis below the neck affecting all of their limbs used an experimental brain-computer interface being tested by the consortium BrainGate.
The interface records neural activity from a small sensor in the brain to navigate things like email and apps.
A recent study in the journal Nature, by scientists at the Swiss research center NeuroRestore, identified a type of neuron activated by electrical stimulation of the spinal cord, allowing nine patients with chronic spinal cord injury to walk again.
Researchers have also been working on brain and machine interfaces for restoring vision. Rao said some companies have developed retinal implants, but Musk's announcement suggested his team would use signals directly targeting the brain's visual cortex, an approach that some academic groups are also pursuing, "with limited success."
Neuralink spokespeople did not immediately respond to an email to the press office. Dr. Jaimie Henderson, a neurosurgery professor at Stanford University who is an adviser for Neuralink, said one way Neuralink is different than some other devices is that it has the ability to reach into deeper layers of the brain. But he added: "There are lots of different systems that have lots of different advantages."

CM Siddaramaiah alleges ‘criminal conspiracy’ in Sringeri recount, vows legal action
Bengaluru (PTI): Alleging a “criminal conspiracy” by BJP candidate D N Jeevaraj in the Sringeri Assembly poll recounting, Karnataka CM Siddaramaiah on Tuesday said the outcome was manipulated after valid postal ballot votes in favour of Congress leader T D Raje Gowda were tampered with during the recounting process.
Following a Karnataka High Court order on an election petition filed by Jeevaraj, challenging Raje Gowda’s election, the reverification and recounting were conducted on Saturday.
After the reverification and recount of postal ballots for the Sringeri Assembly constituency, votes polled in favour of Raje Gowda were reduced by 255, the returning officer said.
A report on the matter has been submitted to the Election Commission of India for further action, the officer added.
Congress leader Raje Gowda had won the 2023 Assembly polls from Sringeri by 201 votes, defeating his nearest rival Jeevaraj.
Addressing a press conference in Bengaluru, Siddaramaiah said the High Court had directed the recounting of postal ballots and that irregularities were noticed during the exercise conducted on May 2.
“This is a clear case of criminal conspiracy,” Siddaramaiah said, alleging that valid votes cast in favour of Raje Gowda were altered after being accepted by counting agents of all parties, including Congress, BJP, and JD(S).
He claimed that during the recounting of postal ballots, 255 votes were initially accepted as valid by all agents but were later tampered with by subordinate officials.
“There is a second mark on the votes polled in favour of Raje Gowda. They had accepted these as valid votes. Subsequently, another mark was made by officials. This is a clear case of criminal conspiracy,” he said.
When asked who was behind the alleged conspiracy, the CM replied, “It was hatched by Jeevaraj and others. It is planned.”
Siddaramaiah further alleged that the returning officer acted improperly by declaring the result despite the presence of an Election Commission observer during the recounting.
“Immediately after the counting, the returning officer announced the result. He should not have done so; this is against the law,” he said.
He pointed out that Raje Gowda had originally won by 201 votes, but after the recounting, the BJP candidate was declared the winner by 52 votes.
“The BJP has committed a criminal act of conspiracy. This is not vote chori but vote dacoity,” he alleged.
The CM said a police complaint had already been filed by Raje Gowda’s election agent, Sudhir Kumar, and emphasised the need for electoral integrity.
“We want transparency and free and fair elections. That is what our Constitution mandates,” he added.
Stating that the government would pursue legal remedies, Siddaramaiah said, “We are preparing an appeal challenging the returning officer’s announcement in a court of law.”
Responding to a separate query on elections in other states, the CM said there appeared to be an anti-incumbency factor in West Bengal, while results in Tamil Nadu were “surprising,” adding that Vijay’s party was emerging as the largest there.
Following the victory of party candidates in Bagalkote and Davanagere South, Siddaramaiah expressed confidence about future electoral prospects in Karnataka.
“Even in 2028, we will win the Assembly elections. We will come back,” the CM said.
Siddaramaiah added that he would order a forensic examination into the alleged tampering of postal ballots.
