Dopamine helps control the brain’s incentive and pleasure centers. This helps us to control our movement and emotions to not only perceive reward, but to attempt to achieve it. People with low doses of dopamine are more prone to addiction. Those with certain dopamine receptors are associated with sensation-hunting. < | Dopamine helps control the brain’s incentive and pleasure centers.

Dopamine connects to receptors quickly and then is rapidly removed if dopamine levels are adequately high. Drugs can affect these levels. Some drugs increase dopamine by preventing dopamine reuptake, leaving dopamine in the synapse. Cocaine and methylphenidate, a therapeutic drug used to treat childhood hyperkinesis and schizophrenia, affect dopamine levels in such a manner. Amphetamine and cocaine also affect behavior and heart function by increasing the amount of dopamine left in the synapse.Cocaine prevents dopamine reuptake, while amphetamine releases more dopamine. Thus, a parallel effect happens through different actions. However, different treatments for addiction will be needed.<ref name=Utex/> | Dopamine connects to receptors quickly and then is rapidly removed if dopamine levels are adequately high.
