ELON: CYBERNETIC LIMBS ARE A GAME CHANGER If someone has lost their arms or legs, combining an Optimus limb with Neuralink could essentially give them cybernetic limbs—like Luke Skywalker in Empire Strikes Back with a robotic hand. This could be a game-changer for amputees, allowing for full neural integration and precise control. A collaboration between Neuralink and Tesla on this would be incredible.

🇺🇸 ELON: HUMAN BRAIN IMPLANTS ARE NOW FULLY FUNCTIONAL "We're going to solve a lot of brain issues, where the brain gets injured or damaged in some way, or didn’t develop quite the right way. What we’re creating with Neuralink is a generalized input-output technology for the brain, a way to get information into or out of the brain, without damaging it or causing negative side effects. This is a very hard problem. Every single one of our implants in humans is working, and working quite well. You’ll get to hear from some of the people who’ve received the implants, in their own words." Source: Neuralink

Elon Musk says people with Neuralink brain chips will eventually "be able to have full-body control and sensors from a Tesla Optimus robot, so you could basically inhabit an Optimus robot. Not just the hand, the whole thing. You could mentally remote into an Optimus robot. The future is gonna be weird, but pretty cool."

ELON: NEURALINK PLUS OPTIMUS COULD GIVE AMPUTEES CYBERNETIC SUPERPOWERS Elon described a future where robotics and brain computer interfaces merge to restore and dramatically enhance human capability. Speaking about long term possibilities, he explained how Neuralink could directly connect the brain to Optimus humanoid robot limbs, allowing people who have lost arms or legs to control robotic replacements as naturally as biological ones. The vision is not just medical recovery, but a leap forward in human ability: “Long term, if you take parts of the Optimus humanoid robot and combine that with Neuralink, let’s say somebody has lost their arms or legs, we could actually attach an Optimus arm or Optimus legs and do a Neuralink implant so the motor commands from your brain that would normally go to your biological arms now go to your robot arms or robot legs.

NEURALINK’S QUIET REVOLUTION: FROM THOUGHT TO TOTAL DEVICE DOMINION Elon detonated a new reality. “Any device that can be controlled via computer or phone can be controlled by a Neuralink implant.” That means everything... cars, drones, even your lights, could soon obey a thought. Neuralink confirmed it: current trial patients are already operating robotic arms using pure brain signals, and expansion to everyday devices is next. The secret lies in Neuralink’s 1,024 ultra-thin electrodes. Each thread is thinner than a hair yet capable of reading and writing neural activity with stunning precision. They don’t just record, they translate intention into action. Compared to Synchron’s vein-based stentrode, which passively listens from blood vessels, Neuralink sits directly on the motor cortex, capturing data with far greater fidelity and speed.

ELON: BRAIN-CONTROLLED ROBOT LEGS ARE ON THE WAY "What we can do is use a Neuralink implant that takes signals from the motor cortex of the brain and also receives signals from the somatosensory cortex. Then give someone who’s lost their legs Optimus' legs. And so you’d be, I mean, we’re really getting like The 6 Million Dollar Man here, from back in the day. And we can actually give someone superhuman cyborg capabilities, like The 6 Million Dollar Man, for less than $6M, even in this day and age. I mean, $6M back then was a fortune. These days, it’s like nothing. But for much less than that, I mean, for something that would be reasonably affordable, it might be more like a $60,000-type thing. And you can take signals from Neuralink, the mind, that would be transmitting to the legs, and transmit those to the attached Optimus robot legs.

Elon Musk says the vast majority of brain diseases are ultimately fixable with a Neuralink device "If you think of the brain like a computer, effectively like a circuit board, you can say if there were some short circuits or some circuits that should be there but aren't, we can fix those Basically, it's kind of like fixing a circuit board. The vast majority of brain issues, I think, are fixable with a Neuralink device. It’s a fine-grained way of reading and writing electrical signals in the brain at high precision If there’s an electrical storm like epilepsy, you can interrupt that storm. In the case of blindness, if somebody's lost their optic nerve or both eyes, you can still stimulate the visual cortex Anything that is a function of signals in or out, if that is the nature of the problem, it can be fixed ultimately with a Neuralink device."

Elon Musk’s company, Neuralink has just received FDA approval to start testing brain chip implants in humans! This is important because Neuralink is working on helping blind people see and solving many types of neurological disorders, like depression, dementia, seizures, strokes, and eventually helping paralyzed people walk. You may have seen a couple years ago they implanted two chips in a monkey to play a video game with just its mind- that same concept will now be tested in paralyzed patients so they can do daily tasks on a computer without needing their limbs. Neuralink is a small (~300 employees), but mighty company, with grand ambitions. The company was started in 2016 by Elon Musk and several others. This major milestone of getting FDA approval is a huge step in bringing this amazing technology to those who need it most. We focus on news and updates related to Neuralink.

Elon Musk explains one of the most optimistic futures imaginable: Neuralink and Optimus restoring lost human abilities through real-world cyborg technology And the first people this could help are the ones who need it most: People who are paralyzed. People who are locked in. People who lost the ability to move, speak, or interact with the world normally like Stephen Hawking Neuralink is already helping patients control computers and robots with their thoughts "They can now communicate almost as quickly as we are communicating right now" “That’s going to continue to accelerate” But Elon’s next vision is even bigger: Use Neuralink to read motor-cortex signals from the brain, combine that with sensory feedback from the somatosensory cortex, and connect it to Optimus-style robotic limbs In simple terms: A person who lost their legs could one day control robotic legs with their mind - just pure thought. No buttons or joysticks Elon called it a real-life “Six Million Dollar Man” concept… but instead of being science fiction or insanely expensive, it could cost around $60,000 Neuralink gives the brain a digital output. Optimus gives the body robotic capability Together, they could create a path for people to walk again, move again, communicate again, and regain independence they thought was gone forever This is the future worth building

Elon Musk Elon Musk on Neuralink: “So, when I emphasized the purpose of Neuralink, like what do we, what's our goal, our goal is to solve important spine and brain problems with a seamlessly implanted device. So, you wanna have a device that you can basically put in your head and feel and look totally normal, but it solves some important problem in your brain or spine. And the reality is that almost everyone, over time, will develop brain and spine problems. These range from minor to very severe, but if you live long enough, everyone's gonna basically have some kind of neurological disorder, from memory loss to brain damage. But the thing that's important to appreciate is that an implantable device can actually solve these problems. I think a lot of people don't quite realise that, but all of your senses, your sight, hearing, feeling, pain, these are all electrical signals sent by neurons to your brain.”

NEURALINK GIVES ALS PATIENT A VOICE LIKE NEVER BEFORE Imagine being stuck in your own head with a thousand thoughts but no way to say them. That was Brad G. Smith’s life with ALS until Neuralink stepped in with a chip that reads his brain signals. Before this brain implant, Smith had to rely on eye-tracking software that only worked in the dark. He joked it turned him into Batman without the gadgets. Now, he can control a computer cursor and talk to his family even in bright daylight. The Neuralink implant uses a thousand tiny wires that pick up signals from his brain and send them to a MacBook Pro. At first, they tried linking it to his hand movements but that was a flop. Turns out his tongue was the star of the show and clenching his jaw worked as a click. Smith says he does not even think about it anymore. His brain just knows what to do, like a pro gamer making split second moves. Thanks to Neuralink, Smith can race his kids in Mario Kart and talk to them faster than ever. He even uses an AI chatbot that comes up with clever replies. Once, it suggested giving a bouquet of carrots to a friend’s horse-loving girlfriend. For Smith, ALS may have taken a lot but Neuralink has given him something priceless: a way to speak up and stay connected to the world. Source: FOX

The Mathematics of Moving a Cursor with Neural Signals What might Neuralink Neuralink be doing Mathematically? Consider the task of moving a cursor without touching it. The machine is not looking for a full thought, a sentence, or an image. For this Control problem, the useful object is an intended movement state. sₜ = (pₜ, vₜ) Here, pₜ is the cursor position at time t, and vₜ is the velocity the user is trying to express. The implant records neural activity through many electrode channels, then the decoder tries to estimate vₜ from that activity. Neuralink’s PRIME material describes the N1 Implant as recording and transmitting brain activity with the goal of enabling computer control. For channel i, a simple population model is rᵢ(t) ≈ bᵢ + aᵢ max(0, dᵢ · vₜ) + ηᵢ(t) where rᵢ(t) is the measured activity, bᵢ is baseline activity, aᵢ is channel gain, dᵢ is the channel’s preferred movement direction, and ηᵢ(t) is noise. One channel is not the command. The useful signal is the pattern across many channels: rₜ = (r₁(t), r₂(t), …, rₙ(t)) The decoder subtracts the baseline vector b and applies a learned map W: v̂ₜ = W(rₜ − b) This gives an estimate of the intended velocity. The cursor then updates by pₜ₊₁ = pₜ + Δt v̂ₜ This is the loop shown in the render: neural activity -> decoded velocity -> cursor motion The cortical network and electrode threads show the measurement side. The N1 Implant is described as using 1,024 electrodes distributed across 64 flexible threads, each thinner than a human hair. The decoder panel shows the computational side with activity rₜ, decoded velocity v̂ₜ, and the cursor state pₜ changing over time. A noisy biological pattern becomes a state estimate. That estimate becomes motion on a screen. Therefore, the first lesson is not that Neuralink makes the brain a screen. For cursor control, the Mathematics is more precise: A small piece of intention is represented as a hidden state, measured through neural activity, decoded as a vector, and turned into action. #Neuralink #BrainComputerInterface #NeuralEngineering #Mathematics #StateEstimation #Neuroscience #MachineLearning #BiomedicalEngineering
