Can you think of a worse way to think about the brain? This is like looking at a picture of a car and trying to study automotive engineering
This picture is just as bad. It nicely outlines functional areas of the brain, but it is hiding the most fundamental 3D arrangement
Now we're getting somewhere, but this still looks like a static flat view of the earth. The brain is probably the most complex part of the vertebrate body, and also the only one that requires 3D visualization to understand the complex relationships between the structures.
