Help me properly remember this study or who wrote about it. It was about some animal that, in experiments, preferred the anticipation centers of their brain -- seeking circuits? -- stimulated over the pleasure centers. I read it in some poppish science book in the last few years and now I'm trying to more accurately recall it so I can use it in a talk, if I'm rembering it correctly. [more inside]
