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."

UP Cong holds statewide protest seeking probe into FIR against Swami Avimukteshwaranand
Lucknow (PTI): The Uttar Pradesh Congress on Wednesday staged a statewide protest demanding a fair and transparent inquiry into the FIR lodged against Swami Avimukteshwaranand Saraswati and those who filed the complaint against him.
In a statement issued here, the party said memorandums addressed to Prime Minister Narendra Modi were submitted through district magistrates in all districts of the state.
Uttar Pradesh Congress spokesperson Manish Hindvi told PTI that the memorandums were handed over through the district administration in all 75 districts.
In the memorandum, the party alleged that Saraswati and his disciples were "unnecessarily harassed and humiliated" by police on the occasion of Amavasya and were prevented from taking a ritual bath (at the Magh Mela). It further alleged that some disciples were manhandled and taken to a police station.
The memorandum also claimed that an FIR was later registered against Saraswati, his disciple Swami Mukundanand Brahmachari and several unidentified persons in a sexual harassment case. It termed the case a "conspiracy" aimed at tarnishing the seer's reputation.
Citing Articles 25 and 26 of the Constitution, the memorandum stated that these provisions guarantee religious freedom and the right of religious denominations to manage their own affairs.
It described the position of shankaracharya held by Saraswati as "one of the highest spiritual posts in Sanatan tradition" and alleged that the entire episode appeared to have been "orchestrated in a planned manner".
"We request that the background of the persons who got the FIR registered be investigated in a transparent manner by a retired high court judge and strict action be taken against them," the memorandum said.
It also sought a "fair and transparent probe" into the allegations levelled against Saraswati so that the truth could be established.
Earlier, Uttar Pradesh Congress president Ajay Rai had told reporters in Varanasi after meeting Saraswati that the party stood firmly with him.
The Congress said it would continue to press for an impartial inquiry into the entire episode.
On February 21, an FIR was lodged in Prayagraj against Saraswati and his disciple Mukundanand Brahmachari on charges of sexually abusing two persons, including a minor, over the past year at a gurukul and religious congregations, including the recently concluded Magh Mela.
Days after he was booked, Saraswati had said on Monday that he would not oppose his arrest and asserted that the "fabricated story" would be exposed sooner or later.
At a press conference on Wednesday, Saraswati alleged that criminals rule in Uttar Pradesh, level allegations and influence investigations, as he denied having any contact with the two persons for whose alleged sexual abuse he has been booked.
