Neuralink & Technologies to Enhance Human Brains | Dr. Matthew MacDougall

Episode 120 Apr 17, 2023 1h 57m 19 insights
In this episode, my guest is Matthew MacDougall, MD, the head neurosurgeon at Neuralink. Dr. MacDougall trained at the University of California, San Diego and Stanford University School of Medicine and is a world expert in brain stimulation, repair and augmentation. He explains Neuralink’s mission and projects to develop and use neural implant technologies and robotics to 1) restore normal movement to paralyzed patients and those with neurodegeneration-based movement disorders (e.g., Parkinson’s, Huntington’s Disease) and to repair malfunctions of deep brain circuitry (e.g., those involved in addiction). He also discusses Neuralink’s efforts to create novel brain-machine interfaces (BMI) that enhance human learning, cognition and communication as a means to accelerate human progress. Dr. MacDougall also explains other uses of bio-integrated machines in daily life; for instance, he implanted himself with a radio chip into his hand that allows him to open specific doors, collect and store data and communicate with machines and other objects in unique ways. Listeners will learn about brain health and function through the lens of neurosurgery, neurotechnology, clinical medicine and Neuralink’s bold and unique mission. Anyone interested in how the brain works and can be made to work better ought to derive value from this discussion. For the full show notes, visit hubermanlab.com.
Actionable Insights

1. Limit Alcohol Consumption

Chronic alcohol consumption leads to significant brain atrophy and thinning of gray matter, with a near-linear relationship between the amount consumed and brain damage, making it a common and avoidable source of harm.

2. Ensure Proper Hydration

Proper hydration and adequate electrolytes (sodium, magnesium, potassium) are critical for optimal brain and body function, as even slight dehydration can diminish cognitive and physical performance.

3. Practice NSDR for Energy

Engage in Yoga Nidra or Non-Sleep Deep Rest (NSDR) sessions, even short 10-minute ones, to greatly restore levels of cognitive and physical energy.

4. Avoid Sleep Deprivation

Sleep deprivation broadly affects the entire brain, diminishing cognitive and motor functions and potentially impairing impulse control.

5. Prioritize Gut Health

Probiotics are vital for gut microbiota health, which in turn communicate with the brain, immune system, and other biological systems to strongly impact immediate and long-term health.

6. Protect Skin From Sun

While sunlight exposure is beneficial, protect your skin accordingly from the sun’s UV radiation to prevent damage and skin cancer, as different individuals require varying levels of protection.

7. Understand Impulse Control

The frontal lobes act as a filter, calming the rest of the brain down from acting on every possible impulse, allowing for controlled behavior.

8. Caution with Amphetamine Use

Be cautious with chronic use of amphetamines like Adderall or Ritalin, as their long-term effects on brain structure and function are not fully understood, beyond increasing addiction risk.

9. Play Video Games for Skills

Playing video games can improve skills like learning and motor execution, and some work suggests it can make surgeons better, so consider it a professional development activity.

10. Utilize Meditation Apps

Use meditation apps like Waking Up to explore different types of meditation and durations, which can place the brain and body into various states and deepen understanding of consciousness.

11. Element Electrolyte Protocol

Dissolve one packet of Element in 16-32 ounces of water first thing in the morning and during physical exercise to ensure adequate hydration and electrolytes.

12. Explore Plasticity Pharmacology

Pharmacologic agents, such as psychedelics, are considered by Dr. McDougall to hold the most promise for broadly impacting neuroplasticity across the entire brain.

13. Avoid Head Injuries

Prevent head injuries and, if one occurs, ensure it is properly treated and avoid subsequent injuries to protect brain health.

14. Consider RFID Implants

Dr. McDougall and his family have small, passive RFID tags implanted in their hands to overcome daily challenges like unlocking doors and storing data, demonstrating the utility of combining devices with the nervous system.

15. Use RFID for Data

Consider using a writable RFID implant for secure, convenient storage of small amounts of data, such as cryptocurrency private keys or access credentials.

16. Don’t Fear Bluetooth EMF

The energy levels from Bluetooth headphones are considered too tiny to cause concern about EMF fields or significant heat damage to the brain, as the body’s cooling system effectively regulates temperature.

Individuals with quadriplegia or those who know someone with the condition are encouraged to visit the Neuralink patient registry to be considered for future clinical trials aimed at enabling control of electronic devices.

18. Support Ethical Animal Research

Acknowledge and support research organizations that prioritize humane treatment of animals, ensuring they are never compelled to participate in experiments beyond necessary procedures and are not deprived of basic needs.

If you are a mechanical, software, or robotics engineer excited about brain-machine interfaces and solving hard problems, consider applying for jobs at Neuralink to contribute to human augmentation and well-being.
