Essentials: Neuralink & Technologies to Enhance Human Brains | Dr. Matt MacDougall

About this video

Huberman revisits his discussion with neurosurgeon Dr. Matt MacDougall of Neuralink. MacDougall describes the brain as a collection of functional modules, and explains that damage to areas such as the frontal lobes can profoundly change impulse control and behaviour. He also describes newer neurosurgical approaches, including using a small drill hole, a fibre-optic cannula and laser heating under real-time MRI guidance to remove deep tumours while sparing surrounding brain. Looking ahead, MacDougall explains Neuralink’s early goal of giving people with paralysis agency over things in the world, and eventually over their own bodies, by linking a brain implant to a spinal-cord implant that bypasses an injury. He also discusses his own passive RFID hand implant, and speculates about longer-term, more direct brain-to-brain and brain-to-internet communication, while stressing that much of that remains far in the future.

Key takeaways

• Dr. MacDougall describes the brain as a set of functional modules, so damage to one area can change specific abilities and behaviour.
• MacDougall describes laser treatment through a small opening, guided by real-time MRI, as a way to remove some deep tumours with less damage to normal brain.
• MacDougall explains that Neuralink’s first aim is agency over external things for people with paralysis, and eventually over their own bodies.
• MacDougall describes bypassing a damaged spinal-cord area with linked brain and spinal implants as a possible route to reconnect brain and body.
• MacDougall says his passive RFID hand implant has no battery and, in his view, could remain in place for life.
