There are different types of buildings in NYC, just like there are different types of neurons. Our neurons need supporting cells and tissues just like buildings need electrical lines. We also have different “burrows” where specific neurons are focused while others are spread out everywhere. Roads are constantly being rebuilt, just like our brain changes. On a small level there is always a lot of change in our brain. Activation is everywhere both in our brain and NYC. There is hardly an isolation of function, and there is a lot happening at once in the brain.
