1·The two halves are linked by a trunkline of between 200 and 300 million nerves, the corpus callosum.
两半部分由2到3亿条神经组成的主干连接，即胼胝体。
2·Scientists have found quite recently that the corpus callosum in women is always larger and probably richer in nerve fibres than it is in men.
科学家最近发现，女性的胼胝体总是比男性更大，神经纤维可能也更丰富。
3·The corpus callosum, which connects the brain's left and right hemispheres and carries traffic essential to many advanced brain functions, steadily thickens.
胼胝体(连接大脑左右两半球，负责传递对高级大脑功能有重要意义的信息)在稳步增厚。
4·Oddly, though, the main connection between the two hemispheres of the brain, which is known as the corpus callosum and is made of white matter, is proportionately smaller in men than women.
让人不解的是，连接大脑两个半球的白质——也叫胼胝体——在男性中成比例地小于女性。
5·Results: White matter density in the left prefrontal cortex and genu of corpus callosum was significantly reduced in both patients and their siblings compared with that in controls.
结果：在左侧前额叶和胼胝体膝部，患者及同胞的白质密度值显著小于正常对照组，患者和同胞之间的差异未达到统计学意义水平。
