Question

Quizplus · Accepted Answer

The release of dopamine within the accumbens is a necessary condition for reinforcement. Studies have shown that drugs that block dopamine release or receptors prevent the reinforcing effects of drugs and natural rewards. Additionally, dopamine levels within the accumbens increase in response to rewarding stimuli, such as food and drugs of abuse. However, dopamine release alone is not sufficient for reinforcement; other factors like expectation and attention also play a role.
