00:00Hi, I am Brad Smith. I am the third person in the world to receive the Neuralink Brain Implant.

00:05I am also the first person with ALS and the first nonverbal, which means that I rely on it for all communication.

00:12I am making this video using the brain-computer interface to control the mouse on my MacBook Pro.

00:17This is the first video edited with the Neuralink, and maybe the first edited with a BCI.

00:22This is my old voice narrating this video, cloned by AI from recordings before I lost my voice.

00:30I want to explain how Neuralink has impacted my life and give you an overview of how it works.

00:35I have ALS, a really weird disease that kills the motor neurons that control my muscles, but not affecting my mind.

00:45My experience has been pretty interesting, starting with a shoulder injury that would not heal,

00:49and ending up with my current status.

00:52I cannot move anything but my eyes, and I am totally reliant on a ventilator to keep me alive and breathing.

01:00My wife, Tiffany, is the best caregiver I could ever imagine.

01:06She does everything for me, with only our kids and friends and family to help.

01:11She is the key to making Neuralink work.

01:14I will stop talking about her because she doesn't like the attention.

01:17Before Neuralink, I had to use an eye gaze control computer for all communication.

01:22It is a miracle of technology, but it is frustrating.

01:26It works best in dark rooms.

01:29So I was basically Batman.

01:31I was stuck in a dark room.

01:34Neuralink lets me go outside and ignore lighting changes.

01:38So how does Neuralink work?

01:40The implant is in my motor cortex, which is the part of my brain that controls body movement.

01:47The actual implant is the size of five U.S. quarters in a stack.

01:50It replaced the hole in my skull.

01:53The threads are placed by a robot just a few millimeters into my brain,

01:56avoiding the blood vessels so there is almost no bleeding.

02:00It connects to the computer via Bluetooth, and the computer does a lot of processing.

02:04This is a feed from the 1,024 electrodes in my brain.

02:09In green, it looks like the matrix.

02:13This is the raw signal that my brain is giving the computer.

02:16The computer has to decide what is important, finding the signal and ignoring the noise.

02:22The Neuralink implant embedded in my brain contains 1,024 electrodes

02:26that capture neuron firings every 15 milliseconds, generating a vast amount of data.

02:32AI processes this data on a connected MacBook Pro

02:36to decode my intended movements in real time to move the cursor on my screen.

02:41Neuralink does not read my deepest thoughts or words I think about.

02:44It just reads how I want to move and moves the cursor where I want.

02:49How do I train the system?

02:53This is how I train the system to interpret my intended movements.

02:57I move the cursor to the bubble and hold over it until it disappears.

03:00The yellow targets are just for holding over, and the blue targets are for clicking.

03:05We initially tried to move my hand to control the cursor, but it was not doing well.

03:11After a lot of research and mapping how body movements match the signals from my brain,

03:16Neuralink engineers found that my tongue was the best for moving the cursor,

03:20and clenching my jaw was best for clicking.

03:22So I train the system with my tongue, and it works much better.

03:27I am not actively thinking about my tongue.

03:30Just like you don't think about your wrist when you move a mouse.

03:34I have done a lot of cursor movements in my life.

03:37I think my brain has switched over to subconscious control quickly,

03:40so I just think about moving the cursor.

03:42This is WebGrid.

03:47It is the way Neuralink and others use to quantify how well they are able to decode intentions.

03:52I click boxes, and it measures my score.

03:55If I click outside the target, my score goes down.

03:58I have reached a top score of 5.

04:01My score was less than 1 before Neuralink with EyeGaze.

04:03You can try WebGrid on Neuralink.com slash WebGrid, and you can see how fast you are.

04:11Tools to make it work.

04:14This is the mixer, which has tools to adjust how the cursor behaves.

04:18First is bias correction.

04:20Because the brain is constantly changing, the cursor drifts over time.

04:24So it is like the cursor moves in a random direction.

04:28This tool lets me adjust how the cursor drifts.

04:31This is a great reason why Neuralink is doing human trials,

04:35because the monkeys cannot explain how the cursor drifts.

04:38Monkeys just give up when bias gets difficult and want snacks.

04:42They are like my children in that way.

04:45This is the speed control.

04:47It changes the speed that the cursor moves around.

04:50Speed also changes across different models and over time.

04:54Able-bodied people can adjust the mouse speed dynamically, and I can do that a bit.

04:57But the speed control sets the baseline speed for the cursor.

05:01I adjust it often.

05:03These are friction and smoothing that are more advanced settings that refine cursor movements.

05:09They might change as Neuralink develops the system.

05:12The last thing is the click stiffness, which adjusts how hard it is to click.

05:18Keyboard and parking spot.

05:19This is the virtual keyboard developed by Neuralink.

05:24I can't move or speak, so I rely on the keyboard for everything.

05:28It gives word suggestions for the situation, and it pushes apps out of the way.

05:33I do a lot of different things with keyboard shortcuts.

05:36So I created a keypad using the Mac accessibility keyboard to make some keystrokes easy to use.

05:42Things like select all, copy, paste, undo, and ways to navigate the page are all really useful,

05:49and I can use the toolbar and some shortcuts.

05:53The other feature I asked for is the parking spot.

05:56Sometimes you just want to park the cursor and watch a video.

06:00The first two participants could use voice commands to pause the cursor.

06:04I could not do that.

06:06So I asked for a way to park it, so it would only come out when I wanted to.

06:10I can go to the bottom right, and the cursor jumps into the circle.

06:15When I want to get out, I have to hit the dots in a specific order, and it jumps out.

06:22When it is in the parking spot, I can watch a show or take a nap without worrying about the cursor.

06:28I heard that the other two people love this feature, the chat app and communication.

06:35The hardest thing about ALS is thinking much faster than I can type.

06:39We have created a chat app that uses AI to listen to the conversation and gives me options to say in response.

06:46It uses Grok3 and an AI clone of my old voice to generate options for me to say.

06:53It is not perfect, but it keeps me in the conversation and it comes up with some great ideas.

06:59My friend asked me for ideas for his girlfriend who loves horses.

07:04I chose the option that told him in my voice to get her a bouquet of carrots.

07:08What a creative and funny idea!

07:11We are also working on a faster way to type with the cursor.

07:14The standard keyboard is designed for two hands to alternate sides.

07:18We found a keyboard designed for a single finger or mouse.

07:21But I know the standard keyboard really well.

07:24Is it faster to start over and learn a new keyboard?

07:28I used Grok AI to make this app to train me on the new keyboard.

07:32I don't know how to code, but Grok walked me through it and wrote the code.

07:36So I am really impressed.

07:39What does it mean for me?

07:40Neuralink has given me freedom, hope, and faster communication.

07:47Overall, the whole Neuralink experience has been fantastic.

07:50It has improved my life so much.

07:53I am so happy to be involved in something big that will help many people.

07:57I have enjoyed working hard with interesting people on important questions.

08:02I am still trying to get faster at communication.

08:05I have spent the past few years with ideas and thoughts that I cannot share

08:09because it takes too much time to type it out.

08:12I can already communicate faster and in more ways than I could before.

08:17And we are still working on ways to get even faster.

08:21Like Noland, the first Neuralink recipient,

08:23I believe that God has put me in this position to serve others.

08:27I have not always understood why God afflicted me with ALS.

08:31But with time, I am learning to trust his plan for me.

08:35I am a better man because of ALS.

08:37I am a better disciple of Jesus Christ because of ALS.

08:41I am closer to my amazing wife, literally and figuratively because of ALS.

08:46I get to work with the brilliant people at Neuralink and do really interesting work.

08:51All because of ALS.

08:54And because we listened when the Holy Spirit told us to move to Arizona,

08:58where Neuralink ended up opening their first site.

09:00Don't get me wrong, ALS still really sucks.

09:03But I am talking about the big picture.

09:06That is what I have learned.

09:08God loves me and my family.

09:11He has answered our prayers in unexpected ways.

09:14He has blessed my kids and our family.

09:16So I am learning to trust that God knows what he is doing.

09:20The big picture is,

09:22I am happy.

09:26Tiffany is the greatest person I have ever known,

09:28and I get to spend eternity with her.

09:30My kids are doing well, especially under the circumstances.

09:34And I can control the computer with telepathy.

09:38Life is good.
