The components of the human reward system

And guess what?There are sugar receptors here, too.They are not taste buds,but they do send signals telling your brain that you're full or that your body should produce more insulin to deal with the extra sugar you're eating.The major currency of our reward system is dopamine,an important chemical or neurotransmitter.There are many dopamine receptors in the forebrain,but they're not evenly distributed.Certain areas contain dense clusters of receptors,and these dopamine hot spots are a part of our reward system.
