27: Til Luchau and Whitney Lowe discuss the most famous (yet, unreplicated) illustration in neuroscience, the sensorimotor homunculus, which purports to show the proportion of the brain dedicated to each body part. Is it accurate?
Episode topics include:
- Is the cortical homunculus a map, or the territory?
- How did it come about? Penfield's methods and limitations.
- How might this all apply to manual therapy and massage?
