A year after being cleared for the test, billionaire Elon Musk’s Neuralink has implanted its wireless brain chip in a human for the first time.
Musk announced that the patient received the implant on Sunday and “is recovering well”. The device is meant to have several applications, from restoring motor functionality within people to enabling a brain-computer interface. There was no independent verification of Musk’s claims, and Neuralink did not offer too many details.
Musk has touted Neuralink as the future of technology and medicine, but ethical concerns have been raised around the chip and its testing.
Here is what you need to know about Neuralink and its human testing.
What is Neuralink, and what does it do?
Neuralink is a brain-chip startup founded by Musk in 2016.
A device the size of a coin is surgically implanted in the skull, with ultra-thin wires going into the brain and developing a brain-computer interface (BCI).
The disk would register brain activity and send it over to a device, such as smartphone, through a common Bluetooth connection.
The first product, called Telepathy, would allow people to control their phones or computers “just by thinking”, said Musk.
Planting the chip in the part of the brain that controls motor function would also enable people to overcome neurological disorders, the company claims.
Musk said that initial users would be those who have lost the use of their limbs.
What is the human trial phase of Neuralink?
The human testing phase will collect data on safety and effectiveness, while helping improve the device.
Musk said on X on Monday that the “initial results show promising neuron spike detection”. This means that neurons are sending electrical and chemical signals to each other around the body. Such activity allows us to carry out our everyday functions from eating to talking.
When Neuralink initially started searching for trial participants in September, it was looking for individuals with diseases of the spinal cord, a key part of the body’s nervous system.
The US Food and Drug Administration approved human trials in May 2023 amid federal probes into the safety of its trials on animals.
The first human received an implant from @Neuralink yesterday and is recovering well.
