image.1581349425864 2Liking (delight) and wanting (desire) usually go together for pleasant rewards, but turn out to have separable brain mechanisms.  Addictions may arise from this liking/wanting separation.  ‘Liking’ is generated by a surprisingly frail and tiny network of hedonic hotspots in brain limbic structures.  ‘Wanting' for the same pleasures has a much more robust and larger brain network involving dopamine systems.  Surprisingly, the ‘wanting’ system also may have a paradoxical relation to fear. The relation between liking, wanting, and fear systems has further implications for understanding clinical disorders beyond addiction, including depression and schizophrenia.
