First Look at the "Structural Core" of the Human Brain

This is one of the first graphical representations of the network structure of our brains. The larger the circle, the more neural connections — highly connected areas create big circles, and areas of few connections are dots. You can see that the biggest circles are concentrated in the back of your brain, roughly in the middle between the two hemispheres. That central position for the core processor might be a result of high chatter levels between the left and right hemispheres of the brain. Though everyone's brain is slightly different, most share this same fundamental neurological pattern. You can see an even more revealing image below.

Basically, this is an early network road map of the human brain. We can use it to figure out not just how we think, but where we think. Literally, we are looking at where thoughts traverse the structures of our brains.
