It wasn’t that long ago that Elon Musk announced that Neuralink, his company aiming to revolutionize brain-computer interfaces (BCIs), had successfully implanted a brain chip in a human.
The first time such a device had been implanted, it marked a leap forward in the realm of BCIs.
Obviously, it’s an incredibly complex bit of tech – but finding out how it works has taken many by surprise.

But before we get into talking about how the tech works, a quick update on the first Neuralink patient.
So far, he’s live-streamed playing chess with his mind, and even shared his first post on X using just his thoughts.
Neuralink starts with a surgeon drilling a hole in the skull of the patient, about the size of a coin.
While that doesn’t sound particularly pleasant, rest assured the patient will have been administered an anesthetic to numb any pain.
Then, a robotic arm carefully inserts the fully implantable and ‘cosmetically invisible’ Neuralink chip.
The chip contains ultra-thin flexible threads, each finer than a strand of hair, that are meticulously weaved into the cerebral cortex, which is responsible for the brain’s higher-level processes like learning and emotion.
These threads are equipped with 1,024 electrodes that record the activity of neurons – the nerve cells that send messages all over the body to drive nearly all human functions.
The coin-sized device is powered by an advanced custom chip within the implant that processes these signals and transports them to a digital device through a standard Bluetooth connection.
Initially focussing on aiding patients with severe paralysis, Neuralink aims to restore personal control over limbs, prosthetics, or communication devices.
Recording and decoding neural signals from individual neurons, then transmitting them back to the brain using electrical stimulation, the chip enables the patient to control devices solely through thought.
When compared to other BCIs, Neuralink targets individual neurons, providing critical data for sophisticated thought-decoding.
What’s more, the company has even developed a robot to surgically implant the device with more precision and efficiency than a human surgeon.
Speaking of which, a doctor in Brazil recently used Apple Vision Pro for ‘game-changing’ surgery.
It’s still early days, but if the technology is successful, the company hopes to create direct brain-to-computer interfaces that connect a person’s thoughts to digital devices.
It’s no secret Musk’s long-term vision is to combine human consciousness with AI, a claim that’s drawn considerable skepticism from scientists.
