中国网浪潮资讯 先前的获胜经历，会使之后的胜利变得更加容易——这就是所谓“胜利者效应”。是什么决定着“胜利者效应”的出现？现在，这一谜团的一角已经被浙江大学求是高等研究院和医学院神经科学研究中心的胡海岚研究组揭开。

CNCAO NEWS The previous experience of winning might render next success to be more easier, which is known as "winner effect". What is the deciding effect of the "winner effect"? Now the research group of Hu Hailan in Qiushi Academy for Advanced Studies ande Center for Neuroscience, Zhejiang University ( ZJU ), has uncovered a little of this mystery.

　　北京时间7月14日，顶级期刊《Science》以长文方式在线发表了胡海岚团队与合作者的研究文章。通过巧妙的实验设计，研究人员在雄性小鼠上首次确定了大脑前额叶皮层对社会竞争的动态控制，第一次发现了哺乳动物大脑中“胜利者效应”的神经环路——中缝背侧丘脑投射往前额叶皮层的环路。

On July 14 Beijing Time, one of the top journals, Science, published the research article written by Hu Hailan's team and partners online in the way of long text. The researchers initially identified the dynamic control of prefrontal cortex ( PFC ) towards social competition and firstly discovered the neural circuit of "winner effect" in mammals' brains, a loop in the dorsal projection of the dorsal raphe to the frontal cortex, through ingenious experimental designs.

　　他们发现，如果增强小鼠的内侧前额叶这一特定脑区的神经活动，就能帮助其在社会竞争中战胜原先高等级的对手，实现“逆袭”。这样的逆袭反复累积到一定程度，小鼠提升的等级就会稳固下来，恰体现出“胜利者效应”。

They found that if enhancing the neural activities in certain area of medial prefrontal cortex ( MPFC ) of the mice, it would help them to beat competitors that were in higher level before in social competition and to achieve "counterattack". And when such counterattacks reached to a certain level after repeated accumulation, the increased level of mice would become steady, which could show the "winner effect".

　　专家表示，这项研究成果为研究社会行为相关的疾病提供了治疗思路，并且为在竞赛中提高选手成绩的行为训练策略提供了理论依据。

Experts stated that this research achievement provided thinking of treatment for studying diseases which were relevant to social behaviors as well as offering theoretical evidence for the training strategy of improving players' performances in competition.
