London Cabbies' Brain Change
- London taxi drivers who learn The Knowledge physically grow the tail of their hippocampus through intense spatial practice.
- That growth coincides with shrinkage in another hippocampal region, producing trade-offs in other memory skills.

- There is no single "normal" brain; averages often describe no actual person.
- Brains vary like body types, so different cognitive profiles suit different problems and teams.
Brains Trade Strengths For Weaknesses
- Differences in brains are not necessarily better or worse; many traits are features with trade-offs.
- Understanding costs and benefits helps decide which cognitive specializations you want to cultivate.
