Elon Musk's start-up Neuralink implants first chip in human brain | DW News

Summary

Human trials have begun in the U.S. for Neuralink, Elon Musk's experimental brain-computer interface designed to help patients with severe neurological injuries such as quadriplegia or paralysis. The implant, placed in the motor cortex, records neural signals and translates them to control devices like prosthetic limbs or computers, enabling communication and mobility. Experts highlight its life-changing potential for patients with specific injuries while noting that claims about mind-reading or memory downloading are purely speculative. Safety is supported by prior animal studies and decades of BCI research, though cybersecurity risks remain low but possible. The technology is targeted at a small, specific patient population.

Takeaways

• 🧠 Neuralink has begun human trials in the U.S. with an experimental brain implant aimed at helping people with severe neurological conditions.

Q & A

What is Neuralink and what is its main purpose?

Neuralink is an experimental brain-computer interface (BCI) developed by a company founded by Elon Musk. Its main purpose is to help people with neurological conditions or severe disabilities, such as paralysis or amputations, to control computers, prosthetic limbs, or communication devices directly with their brain activity.

How does the Neuralink brain chip work?

The Neuralink chip uses over a thousand electrodes to record neural signals from the brain, particularly from the motor cortex, which controls movement. These signals are then transmitted to a computer or prosthetic device, allowing the patient to control the device with their mind.

Who is currently benefiting from Neuralink trials?

The first human trials involve patients with severe neurological conditions, such as quadriplegia, who can potentially regain control over devices like prosthetic limbs or computers, improving their mobility and communication.

What measures have been taken to ensure the safety of Neuralink?

Before human trials, Neuralink conducted extensive preclinical research in animal models, including monkeys and pigs, to demonstrate the device's safety and efficacy. The FDA approved the first human trials based on this evidence.

Has a brain implant been done in humans before Neuralink?

Yes, the very first brain implant in humans was performed in 1998, and there have been incremental advancements in brain-computer interfaces over the past two to three decades.

Is there a risk of hacking with a Neuralink implant?

Yes, any device connected to a computer, including Neuralink, is theoretically vulnerable to hacking. However, the current risk is considered low because the technology is not widespread and is heavily regulated.

Can Neuralink read thoughts or emotions?

No, Neuralink currently only records basic neural signals related to motor control. It cannot read a person's thoughts, memories, or emotions, and claims about downloading memories or mind reading are purely science fiction at this stage.

What types of injuries or conditions could potentially benefit from Neuralink?

Neuralink could help people with severe spinal cord injuries, quadriplegia, paralysis, or blindness caused by neurological damage, allowing them to regain communication, movement, or sensory functions.

Why is this technology considered life-changing for some patients?

For patients with severe neurological damage, Neuralink provides the possibility to regain control over basic functions such as movement, communication, or interaction with devices, which can dramatically improve independence and quality of life.

How long has Neuralink been developing its technology?

Neuralink has been developing its brain chip technology since 2016, building on decades of prior research in brain-computer interfaces.

What is the role of the surgical robot in Neuralink's process?

Neuralink has developed a specialized surgical robot designed to implant the brain chip safely and precisely into the patient's brain, minimizing risk during the procedure.

Are these technologies currently available for general clinical use?

No, Neuralink and similar brain-computer interface technologies are still in experimental stages and are currently intended only for patients with severe neurological conditions, not for the general population.
