- These threads contain electrodes that read brain signals from the motor cortex.
- Craniotomy:
- A small portion of the skull is removed (coin-sized).
- The Link device is seated in this cavity, flush with the skull’s surface.
- Electrode Insertion:
- The robot precisely places 64 to 1,024 channels of electrodes into brain tissue.
- The process avoids blood vessels to minimize trauma and inflammation.
- Device Securing & Closure:
- The Link is secured in place.
- The scalp is closed with sutures or staples; no wires protrude outside the body.
- Initial Testing:
- The device is tested for signal quality and wireless communication post-implant.
4. Postoperative Care & Monitoring
- Immediate Recovery: Monitoring in a neuro-intensive care unit (NICU) for 24–48 hours.
- Short-Term Follow-Up: Neurological checks, wound care, infection prevention.
- Rehabilitation & Training: The patient undergoes training to control digital devices using brain signals detected by the implant.
- Remote Data Monitoring: The device streams brain signals wirelessly to Neuralink’s software for real-time BCI applications.
- Ethics & Safety Reviews: Ongoing oversight by trial sponsors and ethics boards to ensure safety and performance.

🧠 How the Neuralink Chip Works
1. Implant Overview
- Device Name: The Link
- Size: About the diameter of a coin (~23 mm), ~8 mm thick
- Placement: Surgically embedded flush with the skull, over the motor cortex
- Connectivity: Fully wireless, rechargeable via inductive charging (like a smartwatch)
2. Electrodes & Threads
- The Link connects to the brain using ultra-thin, flexible threads (~6 microns thick).
- Each thread contains multiple electrodes (up to 1,024 total in the latest design).
- These electrodes penetrate the cortex and detect electrical signals (action potentials or “spikes”) from neurons.
3. Neural Signal Capture
- Neurons in the brain communicate via electrical impulses.
- The electrodes record these impulses from specific regions (e.g., those controlling hand movement).
- Signals are amplified and digitized on the chip.
4. Signal Processing
- Neural data is sent to onboard processors in the Link.
- These processors use custom algorithms to:
- Identify meaningful patterns
- Decode user intent (e.g., move a cursor left/right)
- Filter out noise
5. Wireless Data Transmission
- The Link transmits data wirelessly via Bluetooth Low Energy (BLE) to a nearby device, like a tablet or smartphone.
- This enables the user to control software like a computer interface, cursor, or robotic limb.
6. Machine Learning Adaptation
- Neuralink software learns each user’s unique brain signal patterns.
- Over time, it gets better at predicting user intent, improving accuracy and speed.
✅ Real-World Application Example (2024)
- The first human user (quadriplegic) used the chip to control a computer mouse with his mind.
- He could move the cursor, play chess, and even browse the internet using only his thoughts.
🔒 Security & Privacy
- Data is encrypted and stored locally or in secure Neuralink servers.
- The chip doesn’t stimulate the brain yet (only reads signals), but future versions may allow stimulation to treat conditions like depression or epilepsy.
Comparison with Traditional BCIs
| Feature | Neuralink | Traditional BCIs |
|---|---|---|
| Electrode Count | 1,024+ | 100-300 |
| Invasiveness | Minimally invasive | Often requires open-brain surgery |
| Data Speed | High-bandwidth (Bluetooth) | Low-bandwidth (wired) |
The Neuralink chip has vast potential beyond current use cases. While early trials focus on medical applications, future versions could revolutionize how humans interact with technology.

Neuralink is navigating a future where tech, ethics, and neuroscience collide—making public discussion, transparent governance, and ethical review essential.
🧪 1. Recognition of Milestone, But Context Matters
- Prof. Tara Spires-Jones (Univ. of Edinburgh) and Prof. Anne Vanhoestenberghe (King’s College London) noted this is a significant milestone in BCI history, but widely used alternatives already exist, and mature clinical proof is still years away (sciencemediacentre.org).
- Dr. Tennore Ramesh and Prof. Andrew Jackson (UK) acknowledged Neuralink’s engineering achievements—wireless transmission and robotic implantation—but found the signal decoding technically impressive yet scientifically underwhelming, as it replicates prior work (sciencemediacentre.org).
📢 2. Criticism Over Transparency & Scientific Rigor
- Critics like Marcello Ienca (Technical Univ. Munich) and L. Syd M Johnson (SUNY) expressed concern that Neuralink communicates primarily through tweets and press releases, bypassing peer-reviewed publication and ethical oversight—violating norms like ClinicalTrials.gov reporting and Declaration of Helsinki standards (forbesafrica.com).
- A Frontiers ethics review reinforced these concerns, noting human trial registration only occurred after the first implant, reflecting a departure from transparent scientific practices (frontiersin.org).
⚠️ 3. Ethical & Regulatory Concerns
- Experts warn about the long-term safety of implants, including risks like inflammation, scarring, and hardware migration .
- Worries about privacy, hacking, and data misuse have been raised as implant technologies become more connected (livescience.com).
- Julia Fourneretis and Susan Schneider debated the philosophical, identity, and societal consequences—especially issues around selfhood, inequality, and AI integration (spheresofinfluence.ca).
🐒 4. Backlash Over Animal Testing
- The scientific community and animal welfare groups have condemned Neuralink’s treatment of monkeys—alleging rushed experiments, multiple primate deaths, “objectionable conditions” cited by the FDA, and potential securities-fraud for misleading claims (wired.com).
🔍 5. Academic Commentary
- Commentary from Forbes Africa and Science Media Centre emphasized: Neuralink brings attention to BCI, but needs to adhere to scientific norms—pausing press-driven hype, publishing data, and ensuring trial integrity (sciencemediacentre.org).
✅ Summary Table
| Area | Expert Outlook |
|---|---|
| Milestone Achievement | Acknowledged within context of existing BCI research |
| Transparency | Strong criticism for lack of peer-reviewed data |
