What were FDA’s concerns over Elon Musk’s Neuralink chip? Premium

Neuralink is making a Class III medical device known as a brain-computer interface. The device connects the brain to an external computer via a Bluetooth signal, enabling continuous communication back and forth. It could revolutionise treatment for conditions such as Parkinson’s disease, epilepsy, and spinal cord injuries.
Since its founding in 2016, Elon Musk’s neurotechnology company Neuralink has had the ambitious mission to build a next-generation brain implant with at least 100-times more brain connections than devices currently approved by the U.S. Food and Drug Administration (FDA).
The company has now reached a significant milestone, having received FDA approval to begin human trials. So what were the issues keeping the technology in the pre-clinical trial phase for as long as it was? And have these concerns been addressed?
Neuralink is making a Class III medical device known as a brain-computer interface (BCI). The device connects the brain to an external computer via a Bluetooth signal, enabling continuous communication back and forth.
The device itself is a coin-sized unit called a Link. It’s implanted within a small disk-shaped cutout in the skull using a precision surgical robot. The robot splices a thousand tiny threads from the Link to certain neurons in the brain. Each thread is about a quarter the diameter of a human hair.
If Neuralink’s BCI can be made to work safely on humans, I believe the potential benefits would make the effort worthwhile.
The company says the device could enable precise control of prosthetic limbs, giving amputees natural motor skills. It could revolutionise treatment for conditions such as Parkinson’s disease, epilepsy, and spinal cord injuries. It also shows some promise for potential treatment of obesity, autism, depression, schizophrenia and tinnitus.
Several other neurotechnology companies and researchers have already developed BCI technologies that have helped people with limited mobility regain movement and complete daily tasks.

How do you create a Christmas tree with crochet? Take notes from crochet artist Sheena Pereira, who co-founded Goa-based Crochet Collective with crocheter Sharmila Majumdar in 2025. Their artwork takes centre stage at the Where We Gather exhibit, which is part of Festivals of Goa, an ongoing exhibition hosted by the Museum of Goa. The collective’s multi-hued, 18-foot crochet Christmas tree has been put together by 25 women from across the State. “I’ve always thought of doing an installation with crochet. So, we thought of doing something throughout the year that would culminate at the year end; something that would resonate with Christmas message — peace, hope, joy, love,” explains Sheena.
