Synchron vs. Neuralink: Comparing Brain-Computer Interface Technologies

Synchron Stentrode: Minimally Invasive BCI

• 💡 Synchron's Stentrode is a brain-computer interface (BCI) that utilizes existing medical technology, similar to a stent used to improve blood flow.
• 🎯 This device is designed to sit within a blood vessel near the brain's motor cortex, detecting signals related to movement intent.
• 🚀 The Stentrode is implanted using a minimally invasive catheter procedure, avoiding open brain surgery, with 10 individuals having received the implant so far.
• 💰 Synchron anticipates the Stentrode to cost between $50,000 to $100,000, comparable to other implantable medical devices.

Neuralink Telepathy: Advanced Electrode Implant

• 🧠 Neuralink's Telepathy implant features approximately 1,000 electrodes, significantly more than Synchron's device, allowing for greater communication bandwidth.
• 🎮 This BCI enables trial participants to control digital devices, including playing video games and operating robotic limbs, with aspirations for controlling humanoid robots.
• 👁️ Neuralink is also developing 'Blindsight', an implant for the visual cortex to restore artificial vision.
• 🤖 The implantation process involves a surgical robot inserting small threads directly into the brain, a more invasive approach than Synchron's.

Key Differences and Future Visions

• ⚖️ Synchron's approach prioritizes a less invasive method and aims for BCIs to become as ubiquitous as keyboards and mice.
• 📈 Neuralink employs a more invasive technique with a focus on achieving bidirectional communication, expanding bandwidth, and potentially offering implants to individuals without medical needs.
• ⚠️ Risks associated with Neuralink's implant include threads retracting or moving, while Synchron's primary risk is blood clots, managed with medication.
• 🌐 Both companies are currently using their BCI technology to help individuals with paralysis control digital devices, with Neuralink expanding its clinical trials to Canada, the UK, and the UAE.
