Episode Details

In this episode of The Feldman Protocol, can the environment you go home to matter more than the brain injury itself? Tommy Wood (MD PhD) makes the case that how you use your brain is the primary driver of how it functions — then digs into CTE mechanics, the myth of the brain "sloshing" in the skull, why animal models of concussion may fundamentally miss the point, ketogenic diets and mental health, AI as orthotic vs. prosthetic, and why obsessing over sleep data might hurt you more than poor sleep.
