But just by the intricacy or the elegance of how these things are, it happens spontaneously with all of the proper checks and balances, so that most of the time, nothing bad happens, which is all quite amazing.

Now the brain may not look like much from the outside a couple pounds of pinkish gray flesh, amorphous but the last hundred years of neuroscience have allowed us to zoom in on the brain, and to see the intricacy of what lies within.
