I picked up a book titled A Better Brain at Any Age (Conari Press, 2009) to try to find out more about my personal command central, and it has the clearest explanation of brain function I've ever stumbled across. I remember learning from geeky Ms. Urich in 10th grade that there were essentially three sections: cerebrum, cerebellum and medulla. Is that right? There was also a corpus callosum somewhere in there. Scientists seem to have a better understanding now than when I was in high school.
