Answer to Question 1

Answer: Humans either smoke regularly or not at all. Smokers find it very difficult to stop smoking, even after suffering diseases that are directly related to smoking. Animals self-administer nicotine and this drug, like cocaine, activates dopamine processes within the nucleus accumbens.

Answer to Question 2

Answer: The mesolimbic dopamine system terminates in the nucleus accumbens. Food for a hungry rat and water for a thirsty rat cause the release of dopamine from the nucleus accumbens, as do drugs that are self-administered (e.g., cocaine and amphetamine).
