Regeneration Potential

Andrew Huberman shares his excitement about a groundbreaking study on neuron regeneration. He explains that while the peripheral nervous system can regenerate, the central nervous system, including the brain and spinal cord, typically cannot. However, research on animals like salamanders, which can regenerate their optic nerves, offers clues for potential human applications 1.

We know that in the peripheral nervous system, if you cut a human nerve or it gets severed, that it will grow back at a rate of about a millimeter per day.

This research could pave the way for new treatments for conditions like glaucoma and spinal cord injuries.

   

Breakthroughs

Huberman discusses a significant breakthrough involving electrical stimulation and gene therapy to regenerate neurons. By using a molecule called mTOR, researchers were able to trick adult neurons into behaving like they were in a developmental stage, leading to unprecedented regrowth and reconnection in the brain 2.

We put in mTOR, which is pro-growth, into these neurons, and basically tricked them into thinking they were baby neurons again.

This technique has shown promise in restoring vision and could have broader implications for treating neural injuries.

   

Scientific Discourse

The evolution of scientific discourse, particularly during the pandemic, has had a profound impact on public understanding. Huberman notes that the polarized views on vaccines have widened the gap in public opinion, making it seem like an all-or-nothing issue for every disease 3.

We have now created, because of the pro-vaccine discourse and the anti-vaccine discourse, I think the gulf has gotten much wider.

This polarization has also affected perceptions of gain-of-function research, complicating the public's understanding of scientific practices.
