🪡 We often get questions about the safety of our implant’s electrode threads. In this video, Dave, a member of our technical staff, shares data highlighting the leap forward in safety that our technology provides.

Check out our latest blog post for more detail!

@elonmusk Would be interesting a study if combining neuralink with microdosing psilocybin from shrooms would improve overall the brain by making new neuron path connections in symbiosis with the neuralink links… 🧠🤯🤖👁️👽

@elonmusk Incredible to see this level of transparency. The future of neural tech will belong to those who prioritize both innovation and safety.

This is absolutely incredible work. I had a brain tumor removed in 2020, and lost some of my lower right peripheral vision as a byproduct. I would love to someday with the help of Neuralink get my vision back!

Neuralink: Now with 98% neuron retention! The other 2%? Just the parts that made you question putting a corporate device in your brain.😎

Amazing ! The astrocytes think that @neuralink threads are just neighbouring axons , they hang together really well ! Congratulations ! 🩵🌟🩵

While reducing glial scarring, the threads risks are mechanical fragility and micromotion-induced inflammation. One underappreciated issue is the foreign body response at the neurovascular unit level: even minimally invasive electrodes can disrupt the blood-brain barrier (BBB), leading to chronic microglial activation, cytokine release (e.g., IL-1β, TNF-α), and eventual neural degeneration near the implant site. Long-term risks also include biofouling from protein adsorption and cellular encapsulation, which can alter impedance and degrade signal quality. Furthermore, miniaturized electronics must manage heat dissipation - exceeding a thermal limit of 1°C increase in surrounding tissue can trigger neuronal apoptosis. Electrode migration, infection risk from transcutaneous connectors, and data security vulnerabilities also compound the safety profile. Emerging strategies include coating electrodes with anti-inflammatory hydrogels or using magnetoelectric stimulation to reduce power requirements and heat.

I know you all are pretty busy right now but, do you think neuralink technology would be able to lessen chronic pain in the future?

I love these deep technically vids. It lays bare the major progress humanity has achieved while showing the road to the future is wide open for progress. Great job to the Neuralink team.

Love this type of video. Dave did a great job of explaining. Do more of these videos.
