Rigid or Plastic?
Human brains look remarkably similar, which might lead us to believe they are built the same and do not evolve over time. Neuroscientists have increasingly used the new field of complex networks to make sense of the brain, and have come to appreciate that, while the brain appears entirely rigid, it is in fact much more plastic than we previously thought.
The brain adapts to our circumstances to help us make better decisions. For example, London cab drivers have much larger [xxx], an area of the brain associated with memory. Their brains have adapted to help them recall the network of London roads, and likely traffic flows. The brain is both rigid and plastic.
