In my opinion our view that the brain is a series of interconnected input/output boxes was overly simplistic. However, I thought that box theory was a good starting point to learn the structures of the brain. I equate box theory with coloring books. When I first learned to draw I needed structure to not scribble. Learning the nervous system is similar to learning to draw, where divisions of the brain break larger boxes into smaller boxes. Now that we have a basic nervous system model as a reference I think we can confidently explore neurobiology and behavior.
