World’s #1 Brain Surgeon: The Truth About Protecting Your Brain After 40

Ask most people what a brain chip does and they will tell you it reads your mind. Dr. Michael Lawton implants these devices, and he says that is not what comes off them. He is President and CEO of Barrow Neurological Institute in Phoenix, the hospital where Neuralink's first human implant was performed, and he has completed more than 10,000 brain operations and clipped around 5,500 aneurysms. Louisa sat down with him inside Barrow to find out what the electrodes actually pick up, how far the technology has come, and where it stops. He walks through the surgery itself. The device goes into the hand knob, one small lobule of the motor cortex, where 64 electrodes have already become 108. The threads carrying them are about a tenth the thickness of a hair, so a robot inserts them while avoiding every arteriole on the surface. You'll hear what Nolan Arbaugh, Neuralink's first patient, can now do with a cursor at world record speed, and why Lawton can't keep up with him in a head to head. Then the correction. The data coming off these electrodes is a train of spikes, the same electrical language every neuron in your head is already using, and decoding it tells you whether a person meant to move a cursor left or right. Reading an emotion, or what someone thinks of you, is nowhere close. The second half turns to the brain Lawton has spent 29 years operating inside. He describes cooling a patient to 15 degrees Celsius and stopping their circulation completely, which shrivels a giant aneurysm like a raisin and opens a short window to repair it. He explains why the hardest cases will still need a pair of human hands, and what he tells trainees who think their craft is disappearing. On brain aging he is direct about what works. He predicts alcohol will be viewed in 20 years the way cigarettes were viewed in the 60s, he takes zero supplements and no peptides, and he says exactly what he can and cannot see when he looks at a living brain on the table. You'll also hear about Barrow's Mindgenuity Labs and its six mysteries of the mind, why he ranks movement as the first one to fall and consciousness as the one that may never be solved, what he believes consciousness physically is inside 86 billion neurons, and the ground underneath all of it. His sister died of a brain tumor. Louisa's father had a stroke in 2019. Both of them have watched this from the other side of the table. *Reduce your risk of Alzheimer's with my science-backed protocol for women 30+:* https://go.neuroathletics.com.au/youtube-sales-page Subscribe to The Neuro Experience for evidence-based conversations at the intersection of brain science, longevity, and performance. _____ *TOPICS DISCUSSED* 00:00 Intro: The Brain Surgeon at Neuralink's First Hospital 00:39 The Guy Who Does the Cases Nobody Else Wants 02:17 A Day in the Life: 5:30am Starts and Three Surgeries 03:20 "Game Tape": Reviewing Every Operation Like an Athlete 04:24 The Surgeon Athlete and Why Surgery Is a Physical Skill 05:32 Fifty Years From Now: What Happens to Neurosurgery 06:11 The ROSA Robot and Mapping a Seizure Focus 08:16 Deep Brain Stimulation and Hitting an Exact Target 08:52 Will We All Be Operated On by Robots? 10:02 The Brain AVM: The One Case a Robot Can't Take 11:18 Why Bleeding Breaks a Robot: The Waymo Problem 13:15 What a Brain-Computer Interface Actually Does 14:49 The Hand Knob: 108 Electrodes in One Small Spot 15:50 Cursor Control at World Record Speed 16:31 Inside the Implant: Threads a Tenth the Width of a Hair 17:27 "No, the Chip Cannot Read Your Thoughts" 17:58 What the Device Really Reads: A Train of Spikes 19:18 From Movement to Sensation: What Comes Next 19:48 Why Restoring Sight Is So Much Harder 20:58 The 1943 Paper That Predicted All of This 22:37 Elon, Telepathy, and What's Actually Possible 23:00 Boosting Creativity and Intelligence in 50 Years 25:10 "When I Retire, We'll Be Treating Depression and Addiction" 26:04 Alzheimer's: Light Therapy and the Blood-Brain Barrier 27:11 Treating the Disease vs Preventing It 28:25 10,000 Operations: How He Feels About Robots Taking Over 29:54 Neuroplasticity: How Nolan's Brain Learned the Device 31:34 What Actually Changes at the Neuron Level 32:04 Patient Two and the Robotic Arm 32:42 5,500 Aneurysms: The Cases That Stay With Him 33:16 Cardiac Standstill: Cooling a Brain to 15 Degrees 35:46 What Separates a Great Surgeon From an Average One 36:17 Traits of Greatness: The Formula Nobody Has Cracked 37:21 The Phone Call in the Middle of a 16-Hour Surgery 39:35 "I Must Have Been Born for This" 41:26 Can You Tell How Old a Brain Is Just by Looking? 43:12 Why Alzheimer's Is Invisible in a Living Brain 44:14 What a Neurosurgeon Does to Protect His Own Brain 44:40 "Alcohol Will Be Viewed Like Cigarettes in the 60s" 45:13 Peptides, Injectables, and Zero Supplements 46:52 The Last Generation to Operate With Open Hands 48:10 How Louisa Found Him on Twitter in 2021 48:5
