Neuralink’s Blindsight: Making Monkeys See Things That Aren’t There

Scientists have successfully tricked a monkey’s brain into seeing something that wasn’t actually there using a computer chip planted directly into its skull.

The Experiment That Fooled a Monkey’s Mind

Deep inside a research laboratory, scientists from Neuralink Corporation conducted an experiment that sounds like something from a nightmare. They placed a tiny computer chip inside a monkey’s brain and used it to make the animal see things that existed only in the machine’s memory.

The device, called Blindsight, sends electrical signals directly to the parts of the monkey’s brain that control vision. Joseph O’Doherty, an engineer working for the company, revealed these disturbing details at a scientific meeting on Friday. He explained that at least two out of every three times they tried the experiment, the monkey moved its eyes toward whatever the researchers wanted it to see — even though nothing was actually there.

This marked the first time Neuralink has shared results from their Blindsight tests with the public. The brain chip works by copying what a normal eye does, but instead of light entering through the eye, electrical signals go straight into the brain tissue.

A Technology That Blurs Reality

The Blindsight system represents a dark frontier in brain technology. Scientists are pushing the boundaries of what machines can do to the human mind, testing how far they can go in treating conditions that have puzzled doctors since the beginning of time.

The company’s immediate goal involves helping blind people regain their sight. But their long-term plans venture into more unsettling territory. Elon Musk, who owns Neuralink, has spoken about creating “superhuman vision” that would allow people to see in infrared light — abilities that go far beyond what nature intended for human eyes.

For several years now, Neuralink has been conducting these experiments on monkeys. Musk announced in March that the company hopes to begin testing the device on a human subject sometime this year. The thought of a person walking around with artificially created visions playing in their mind raises questions about what is real and what is manufactured by machines.

When questioned further about the company’s work at the conference, O’Doherty refused to provide additional details.

Humans Already Living with Brain Chips

The monkey experiments are not Neuralink’s only venture into human brain manipulation. The company has already implanted devices into five people who cannot move their bodies due to paralysis. These chips allow the patients to control computers using only their thoughts.

According to O’Doherty’s presentation at the Neural Interfaces conference, three people received these implants in 2024, and two more received them in 2025. Some patients now spend about 60 hours each week connected to their Neuralink devices — nearly the equivalent of a full-time job spent plugged into a machine.

Neuralink is just one of several companies working in this growing field of brain technology. The race to control human thoughts and movements through computer chips has attracted multiple competitors, each pushing deeper into the mysteries of the human mind.

The Promise of Movement for the Paralyzed

Future versions of this brain technology could allow paralyzed people to walk again, according to Musk’s claims. O’Doherty worked with academic researchers on an experiment that demonstrated this possibility. They used a Neuralink implant to send signals to a monkey’s spinal cord, forcing its muscles to move against the animal’s will.

Other research teams have been working on spinal cord stimulation for years, trying to restore movement to people who have lost the ability to control their own bodies. The idea of machines taking control of human muscles and making them move creates an eerie picture of what the future might hold.

The technology works by bypassing the normal pathways that carry signals from the brain to the muscles. Instead of relying on the body’s natural systems, the machine creates its own electrical highways directly through the nervous system.

A Stepping Stone to Something Bigger

These medical applications serve as practice for Musk’s ultimate goal — something far more ambitious and potentially frightening. He wants to increase the speed at which all humans can communicate, not just those with medical conditions. This would involve implanting chips in healthy people’s brains.

Musk has stated that this technology could help humanity “mitigate the risk of digital super-intelligence.” He believes that by connecting human brains directly to computers, people might be able to keep up with artificial intelligence systems that grow more powerful each day. Musk is simultaneously building these AI systems through his other company, xAI Corporation.

The vision involves a world where thoughts move between human minds and computer networks at electronic speeds, where the boundary between human consciousness and artificial intelligence becomes increasingly blurred.

The Mechanics Behind the Vision

The Blindsight system will eventually include a pair of special glasses that work together with the brain chip, according to O’Doherty’s presentation. These glasses would likely capture visual information from the real world and translate it into electrical signals that the chip sends directly to the brain.

Testing on monkeys offers certain advantages for the researchers. The part of a monkey’s brain that processes vision sits closer to the surface than the same area in human brains. This makes it easier for scientists to reach with their instruments and electrodes.

However, when the technology moves to human testing, Neuralink plans to use a surgical robot to place implants deeper inside people’s brains. The robot would drill through skull bone and brain tissue to reach the areas that control human vision.

Questions Without Answers

The results from monkey experiments leave many questions unanswered. Scientists cannot predict how well the technology will work when transferred from monkey brains to human brains. The device has not received approval for human use in the United States, meaning government regulators have not yet decided whether the technology is safe enough for people.

Each successful test on laboratory animals brings the technology one step closer to widespread use in humans. The monkeys that see things that aren’t there today might be the first glimpse of a future where machines routinely create false realities inside human minds.

The line between helpful medical treatment and technological manipulation of human consciousness continues to blur as these experiments progress. What begins as an attempt to restore sight to the blind could evolve into something that fundamentally changes what it means to see, to think, and to be human.
