A Neuralink technician revealed on Friday that the company’s “Blindsight” device, designed to stimulate areas of the brain associated with sight, has shown promising results in early trials. In at least two-thirds of cases, monkeys with the implant moved their eyes toward objects researchers were attempting to have the brain visualize, marking a significant step forward in the quest to restore vision through brain-computer interfaces.
Neuralink’s Blindsight: How It Works
Neuralink’s “Blindsight” implant aims to bypass damaged or non-functioning eyes by directly stimulating the visual cortex, the part of the brain responsible for processing visual facts. The device uses a series of electrodes to deliver targeted electrical impulses, effectively “painting” images directly onto the brain. This approach holds potential for individuals who have lost vision due to injury or disease affecting the eyes or optic nerve.
Did You Know? The visual cortex is located in the occipital lobe, at the back of the brain.
Monkey trials Pave the Way for Human Testing
Neuralink has been conducting Blindsight tests on monkeys for several years. The company has found that monkeys are ideal for initial testing as their visual cortex is closer to the brain’s surface than in humans, making access easier. The success of these trials is crucial for refining the technology and ensuring its safety before moving to human subjects.
The company hopes to begin human trials with the Blindsight device later in 2025. Cortical blindness, which results from damage to the visual cortex, affects a significant number of people worldwide, and Blindsight offers a potential solution where other treatments have failed.
Neuralink’s Broader Mission: Brain-Computer Interfaces for All
Neuralink is one of several companies working on brain-computer interfaces (BCIs), which aim to allow humans to interact with computers and other devices using only their thoughts. While Blindsight focuses on vision restoration, Neuralink’s broader goals include developing BCIs to treat a wide range of neurological conditions, including paralysis. The company has already implanted devices in five people, three in 2024 and two in 2025, who use them for around 60 hours a week to aid communication.
Pro Tip: BCIs hold immense potential for revolutionizing healthcare, communication, and human augmentation.
Timeline of Neuralink Implants
| Year | Number of Implants | Application |
|---|---|---|
| 2024 | 3 | Communication Assistance |
| 2025 | 2 | Communication Assistance |
| Future | TBD | Vision Restoration, Motor Control |
Elon Musk has previously stated that brain implants with similar technology could one day enable paralyzed individuals to move or walk. He has also hinted at using the technology to enhance the capabilities of healthy individuals, raising both excitement and ethical concerns about the future of BCIs. The FDA plays a crucial role in regulating these devices.
Ethical considerations and the Future of BCIs
As BCIs become more complex, its essential to address the ethical implications of this technology. Questions surrounding data privacy, cognitive enhancement, and equitable access must be carefully considered to ensure that BCIs benefit all of humanity.

Evergreen Insights: Background, Context, Past Trends
The field of brain-computer interfaces has been developing for decades, with early research focusing on restoring motor function to paralyzed individuals. Recent advances in microelectronics and neuroscience have made it possible to create smaller,more powerful,and more precise BCIs. Neuralink is at the forefront of this revolution, pushing the boundaries of what’s possible with brain-computer interfaces.
