I apologize, this is pedantic, but I think people often overstate the relationship between neural networks and the brain. I'm far from an expert, but saying neural networks are based on the brain is a stretch. They're inspired by a theory of how the brain works that is not wholly in line with what most scientists believe.

It's so tempting to say, this is based on the brain, when really it's more like, this was inspired by one psychologists model of the brain.
