You never know with science. You can find complexity in simple things (chaos theory/butterfly effect, quantum mechanics) or simplicity in complex things, you just never know. It turns out there is a grid or scaffold of simplicity underlying the arrangement of the brain. This is a wonderful thing to find, like Maxwell's equations relating electricity to magnetism or the gas laws of chemistry; more accurately, it's like a simple coordinate system (or map/address book?) that can be used for future studies of the brain. I'm sure when we dig a little deeper that there will be some maddening complexity that confounds us again, but today let's revel in the simplicity given to us!
