  So we kind of already know what parts of the brain are involved (here’s a pretty good diagram ), we just need to know how they all work together to make us want things.
  
  This is important for us to help effectively treat all kinds of addictions, as well as to find ways to motivate people into healthier behaviors (can you imagine if eating healthy foods felt as good as eating junk food??)
