The reward system in our brain exists to ensure we seek out what we need. If eating nutritious food or being smiled at pleases us, we try to secure more of these stimuli. However, seeking pleasure can also result in people becoming addicted, indebted or overweight.

In 1986, a discovery was made that dopamine did not produce pleasure, but in fact, desire. While dopamine makes us want, pleasure comes from opioids and endocannabinoids ( a kind of marijuana produced in the brain), which paints pleasure on good experiences.

We cannot explain away our minds by brain mechanisms. Brain mechanisms are part of our minds.

Understanding that desire and dread, for instance, share the same brain operations, could help ease schizophrenia symptoms by restricting a particular dopamine neuron that produces fear.

One of the key things in pleasure is that it comes in cycles. 

The hungry desire state before a meal could produce pleasure from the anticipation of good food. Then, while eating, pleasure dominates, but desire could still come for more salt or a drink until satisfied. If we switch to the d...

Advertising and availability are also tempti...

Something as simple as dropping your keys once will fire dopamine neurons. But, if you drop them a few more times, the neurons will get bored and stop taking notice.

The market economy has increased the dopamine-wanting system. If you can give the consumer novelty, they will continuously wa...

Taming the dopamine desires

The best way of resisting is not to linger over the temptation, but to decide to move away from it, as witnessed in the marshmallow tests.

Mindfulness meditation may also help. It's not that meditation makes the wanting go away - it's giving the more cognitive mind a way of distancing itse...
