• I wrote this test to give you a better understanding of brain dominance according to me.  To be honest I am not a scientist so this test will only tell you what I have come to understand about the corpus callosum, or what I call the middle brain.  I break down the different brain dominance patterns into 9 types: front left-brain, front middle brain, front right-brain, middle left-brain, middle middle brain, middle right-brain, back left-brain, back middle brain, and back right brain.  Now that you are completely bored I will show you how each of the brain types is a genius in its own little way.  You'll know which one you are.
