===Motivation===
While all pleasurable stimuli can be seen as rewards, some rewards do not evoke pleasure.<ref name=pmid26109341/> Based upon the [[incentive salience]] model of [[reward system|reward]] – the attractive and motivational property of a stimulus that induces [[approach behavior]] and [[consummatory behavior]]<ref name=pmid26109341/> – an intrinsic reward has two components: a "wanting" or desire component that is reflected in approach behavior, and a "liking" or pleasure component that is reflected in consummatory behavior.<ref name=pmid26109341/> Some research indicates that similar [[mesocortical pathway|mesocorticolimbic]] circuitry is activated by quite diverse pleasures, suggesting a common neural currency.<ref name=pmid25950633>{{cite journal |last1=Berridge |first1=Kent C. |last2=Kringelbach |first2=Morten L. |title=Pleasure systems in the brain |journal=Neuron |date=6 May 2015 |volume=86 |issue=3 |pages=646–664 |doi=10.1016/j.neuron.2015.02.018 |pmid=25950633 |pmc=4425246 }}</ref> Some commentators opine that our current understanding of how pleasure happens within us remains poor,<ref>"How we and our hedonic experience are situated or constituted in our brains and organisms remains to be seen."Conclusion, Pleasure, Stanford Encyclopedia of Philosophy, https://plato.stanford.edu/entries/pleasure/</ref><ref>{{cite journal |last1=Moccia |first1=Lorenzo |last2=Mazza |first2=Marianna |last3=Nicola |first3=Marco Di |last4=Janiri |first4=Luigi |title=The Experience of Pleasure: A Perspective Between Neuroscience and Psychoanalysis |journal=Frontiers in Human Neuroscience |date=4 September 2018 |volume=12 |pages=359 |doi=10.3389/fnhum.2018.00359 |pmid=30233347 |pmc=6131593 |doi-access=free }}</ref> but that scientific advance gives optimism for future progress.<ref>"prospects seem good for new and deep scientific understanding of pleasure and of how it is organized in the brain."
