Question: does the size of your brain matter in terms of knowledge, memory, etc.?

Melanie Stefan answered on 18 Mar 2011:

What matters is the number of neuronal connections. In a larger brain, there will be more of them, which is why we are a bit cleverer than a fruit fly. But between two people, say, the difference isn’t huge, so I don’t think that people with bigger heads are more knowledgeable or intelligent or anything like that.
