SUGAR!!!!!A colleague was looking for examples and descriptions for the economic idea of diminishing marginal utility. He ran across this video on sugar and the brain. It deals with taste buds, brain parts, dopamine and all sorts of brain and physiology ideas. It's only 5 minutes and has some fun graphics to keep the kids interested. Not all the various terms we use are in here, but may are referenced. Check it out.
