I like this.
Taken from "The Geography of Bliss"
"Neuroscientists at the University of Iowa have identified the regions of the brain associated with good and bad moods. They do this by hooking up research subjects (college students in need of quick cash) to MRI machines and then showing them a series of pictures. When they show people pleasant pictures-bucolic landscapes, dolphins playing- parts of the prefrontal lobe are activated. When they show unpleasant images- a bird covered in oil, a dead soldier with parts of his face missing- the more primitive parts of the brain light up. Happy feelings, in other words, register in parts of the brain that have evolved most recently. It raised and intruiging question: Are we, in evolutionary if not personal terms, slouching towards happiness?"
