大脑中那些神经的连接构成亿万世界

2011年，扎哈沙德与她在加州大学洛杉矶分校的同仁们进行了一项针对健康双胞胎的脑成像研究以追踪大脑中的连接情况，该研究共涉及147名女性和87名男性。她后来发现，在人脑额叶区中存在着“显著”的性别差异，该区域与自控力、决策力和演讲能力都息息相关。

In the most comprehensive study so far, scientists led by biomedical analyst Ragini Verma at the University of Pennsylvania found the myriad connections between important parts of the brain developed differently in girls and boys as they grow, resulting in different patterns of brain connections among young women and young men.

在目前为止最全面的一项研究中，以宾夕法尼亚大学(the University of Pennsylvania)生物医学分析专家拉吉尼・维尔马(Ragini Verma)为首的科学家们发现，大脑重要部位之间的诸多连接随着男孩、女孩的成长而演化出差异，导致年轻女性和男性的脑内连接模式不同。

The team imaged the brains of 949 healthy young people, 521 females and 428 males, ranging in age from 8 to 22. Like Dr. Jahanshad's team, Dr. Verma employed a technique called Diffusion Tensor Imaging to trace how water molecules align along the brain's white-matter nerve fibers, which form the physical scaffolding of thought. The study was reported earlier this month in the journal the Proceedings of the National Academy of Sciences.
