anonymous on 16 Nov 10"Neuroscientists understand the structural bases of some of these qualities. Take language, that uniquely human behavior. Underlining it are structures unique to the human brain - regions like "Broca's area," which specializes in language production. Then there's the brain's "extrapyramidal system," which is involved in fine motor control. The complexity of the human version allows us to do something that, say, a polar bear, could never accomplish - sufficiently independent movement of digits to play a trill on the piano, for instance. Particularly striking is the human frontal cortex. While occurring in all mammals, the human version is proportionately bigger and denser in its wiring. And what is the frontal cortex good for? Emotional regulation, gratification postponement, executive decision-making, long-term planning. We study hard in high school to get admitted to a top college to get into grad school to get a good job to get into the nursing home of our choice. Gophers don't do that."
