I disagree that is the reason we haven't understood the brain. If we could replicate the underlying process, we could attempt to simulate a brain and maybe successfully so, even if we don't understand why it works. The main problem seems to be that we actually don't understand all the building blocks, at least according to the article: > There are fundamental questions left unanswered: What information do neurons represent? How do neurons connect to achieve that? How are these representations learned? Until we figure out how and why connections are created between neurons, we only know how the brain responds to stimuli it has already learned, but not how it learns new information.
