Problem:
I'm trying to understand what neuroeconomics is. There are two possibilities for what it might mean.
(1) The study of cognitive processes in the brain by applying basic principles of economic theory like concepts of utility, decision making, etc.
(2) The study of how a human behaves in an economic setting, somewhat like game theory and so on, which is more economics than brain science.
Question: Which one is it?
Any ideas? Or better yet, pointers to places where this has already been answered?
