中文摘要：

对奖赏刺激反应性减弱是重度抑郁症（MDD）的重要表现。功能性磁共振成像（fMRI）在抑郁症奖赏的脑影像学研究中发挥着重要作用。本文就事件相关fMRI在MDD奖赏刺激反应中的研究进行综述。

英文摘要：

Reduced responsiveness to reward stimuli is a central feature of major depressive disorder（MDD）.Study on the changes of neural substrates and behavior contributes to understand the mechanism of MDD.Functional magnetic resonance imaging（fMRI） has the unique advantage of investigating reward processing,which is of importance in the brain imaging study.The progresses of event-related fMRI（ER-fMRI） in field of rewarding stimuli in major depressive disorder were reviewed in this article.
