If it’s not obvious from the monkey painting, @neuralink runs the best animal research program in the world. Advancing the science and engineering of animal care is an internal mandate and imo progress rivals the technical advancements in N1.

Thanks for the conversation @lexfridman. You are tremendously talented and a joy to spend time with.
Here's my 8.5 hour conversation with @elonmusk & @neuralink team. It is the longest podcast I've ever done! 🤯 It's a fascinating, super technical, and wide-ranging conversation. It's here on X & everywhere else, including YouTube: On X, it's split up

I am the 3rd person in the world to receive the @Neuralink brain implant. 1st with ALS. 1st Nonverbal. I am typing this with my brain. It is my primary communication. Ask me anything! I will answer at least all verified users!. Thank you @elonmusk!

I love this description of a calibration bug that arises with early models (46min mark): “When I’m staring at the screen trying to move a cursor its incredibly shaky but as soon as I close my eyes the cursor is still and doesn’t move at all”. If you’ve shipped ML products in the.

Nudge Zero uses piezoelectric transducers to generate tiny sound waves from hundreds of different sources at once. By precisely controlling the start time of each wave, we ensure they arrive at a target simultaneously, constructively interefering to produce a much bigger

Cool academic work on BCI for speech decoding!.
Our new study is out today in the New England Journal of Medicine! We demonstrate a speech neuroprosthesis that decodes the attempted speech of a man with ALS into text with 97.5% accuracy, enabling him to communicate with his family, friends, and colleagues in his own home. 1/9

Academic work over the last several years has demonstrated that focused ultrasound energy provides non-invasive control of neural activity in deep brain regions. If you’re curious how sound can modulate the behavior of neurons, I recommend reading this work by @mikhailshapiro:.

Using advanced modeling, we are able to electronically steer a focus to form over target brain structures with accuracies of ~1mm. Importantly, focused ultrasound has the capacity to engage deep regions of the brain that were previously only accessible through invasive surgery.

I would love to hear a choir sing with their thoughts. Cool early work in this direction:.
Excited to share our NEW preprint: a "brain-to-voice" neuroprosthesis that directly synthesizes voice from neural activity with closed-loop audio feedback. It allowed a man with ALS to speak expressively by modulating intonation & sing melodies via BCI! 1/

If you want to build the future of human computer interaction and have shipped awesome stuff in the past, reach out!. "Design is not just what it looks like and feels like. Design is how it works.".
Neuralink has created an app that decodes movement intention from brain signals recorded by the N1 Implant, allowing you to control a computer with your thoughts.

Advancing the science and engineering of animal research is one of the reasons I'm excited to go to work every day. I'm proud we use our resources to unlock new refinements and light the path forward for the entire community to be less wrong.
The company would argue that it's advancing animal care in ways similar to how it's advancing implants. It does not withhold food or water from the animals to goad them into doing tests. It's been thought that the animals would not . .
