      Caffeine is the most widely used psychoactive substance and has sometimes been considered a drug of abuse. Classic drugs of abuse lead to specific increases in cerebral functional activity and dopamine release in the shell of the nucleus accumbens (the key neural structure for reward, motivation, and addiction). In contrast, caffeine at doses reflecting daily human consumption leads to a release of dopamine in the prefrontal cortex, which is consistent with its reinforcing properties. How much do you know about the neurologic effects of caffeine? Test yourself with our quick quiz.
