What is dopamine, and how does it impact addiction?
What will be an ideal response?
Dopamine is the neurotransmitter responsible for delivering pleasure signals to brain nerve endings in response to behavior that makes us feel good. The role of dopamine in the brain is critical to addiction. The bloodstream delivers drugs to the area of the brain that produces dopamine, thereby triggering the production of a large amount of the substance in the brain. Over time, the continued use of drugs physically changes the nerve endings, called receptors. To continue operating in the presence of large amounts of dopamine, the receptors become less sensitive, meaning that greater amounts of any particular drug are required to create the amount of dopamine needed for the same levels of pleasure.
