What do we know for sure about the brain

If I was going to list everything we knew for sure about the brain, it would be a very, very long list. Instead of trying to do that, I am going to focus on things we know relevant to my last post, which was quite negative about the new "brain mapping" initiative, and which generated a lot of criticism
(http://www.psychologytoday.com/blog/fixing-psychology/201304/why-brain-mapping-is-stupid-idea). The title of the post then, should maybe be less “What do we know about the brain?” and more “What are some first principles we can use to understand how the brain operates?”

Why the Brain Mapping project is a Stupid Idea

It was just announced that President Obama wants to start spending one hundred million dollars to "map the brain", and that his oft-times rival Eric Cantor thinks it’s a great idea. But it is a terrible idea, because I can tell you, right now, about half of the big lessons they will learn. Plus, for about a million dollars, I could probably gather a group of experts together to tell you about half of what remains. I'm not sure what, exactly, would be left after that, but I'm sure it would be comparatively cheap to figure out.
