Neurophobia
Many people who study the brain (or just want to read about it in their spare time) assume they have to understand….. the brain. As in the whole brain. But with 100 billion neurons and 10,000 connections between each one firing 10 times a second, that’s really a bit much to expect of yourself. In the end most of us focus in on just one level of the brain’s hierarchical organization – the gene level, or the cell level, or the region level, or the circuit level – and essentially leave thinking about the rest of the brain to someone else.

For most psychologists, the level at which they intuitively attempt to understand the brain is at the whole-brain level. As an analogy, if the brain were the United States, and the psychologist were a bird, she would be flying at around 36,000 feet on a clear day – roughly the height of a jet plane crossing the country. From that height you can see whole brain regions the way a plane can see whole states. “Hey! There’s the dorsolateral prefrontal cortex – I mean California – that’s where American culture makes its decisions. Hey! There’s the amygdala – I mean Louisiana – that’s where Americans feel constantly in danger. Hey! There’s the motor cortex – I mean Texas – that’s where American culture is obsessed with physical prowess.”
