Read through just as easily as if the world were normal: 3+ words and first/last letter in right place. Back to front (evolution old to new, simple to confusing) Evolutionary direction of function & morphology (back to front, inside to outside)(except cerebellum) Brainstem/hindbrain, limbic system, & sub-cortical areas, cerebral cortices. Pfc has been growing dramatically over evolutionary time and cerebellum as well! A lot of these higher cognitive things. Associated with movement, motor functions, empathy, decision making, higher cognitive, motivation. 2 areas are very neuroscience research is now. Connected by corpus callosum (bundle of fiber that connected l and r side) For several decades until the 1960"s it was not uncommon to cut the corpus callosum to attempt to help people with epilepsy. If you have severe epilepsy, if you can isolate it to smaller areas, they can control it / minimize severity of seizures. People are ok if we cut it.
