 In another example, activated self-stimulation electrodes in the lateral hypothalamus of rats increase appetite, but also cause more adverse reactions to tastes such as sugar and salt; apparently, the stimulation increases wanting but not liking.Such results demonstrate that our reward system includes independent processes of wanting and liking.The wanting component is thought to be controlled by dopaminergic pathways, whereas the liking component is thought to be controlled by opiate-benzodiazepine systems.
