They have discovered that taxi drivers have actually grown more brain cells because of all the kn

2、owledge they keep in their heads.When the scientists compared the brains of taxi drivers with those of other drivers, they found the taxi drivers had more grey matter in the area of the brain associated with memory.They believe that this part of the brain, the mid-posterior hippocampus, is where cab

3、 drivers store a mental map of London, including up to 25,000 street names and the location of all the major tourist attractions.The research is the first to show that the brains of adults can grow in response to specialist use. It has been known that area of childrens brains can grow when they lear

7、让他们的大脑更发达科学家认为，卫星导航系统会让人的大脑变得迟钝，阻碍其发展。他们发现，由于出租车司机要记住大量的道路信息，他们脑细胞的数量比普通人要多。科学家在对比出租车司机和其他驾驶员的脑部结构后发现，出租车司机脑部与记忆力有关的区域存在更多的脑灰质。科学家认为，这部分大脑叫中后海马区，是出租车司机储存伦敦地图的地方，这幅地图上包括2.5万个街道名称和所有重要的旅游景点的位置。这一研究首次表明，成年人的大脑会因特殊的使用而生长发育。此前人们就知道，儿童学习音乐或语言会促进他们的脑部发育。科学家警告说，卫星导航系统日益普及，有望成为这次圣诞节最畅销的礼品之一，可能会改变这一切。这项研究的负责人，伦敦大学学院的埃莉诺马奎尔说：“全球定位系统可能会对脑部产生重大影响。”我们很希望他们还要开始使用卫星导航系统。我们相信，由于出租车司机必须记住大量的数据资料，大脑那个
