词汇之间又是如何关联的？
最近，加州大学伯克利分校Gallant实验室的科学家通过fMRI和听读实验，对许多常用英语单词在大脑中的反应区进行了定位，从而发现了很多词汇之间有趣的关联。科学家通过可视化建模手段，将其绘制成了动态地图，名曰：mantic maps.tooploo

Abstract: The meaning of language is reprented in regions of the cerebral cortex collectively known as the ‘mantic system’. However, little of the mantic system has been mapped comprehensively, and the mantic lectivity of most regions is unknown. Here we systematically map mantic lectivity across the cortex using voxel-wi modelling of functional MRI (fMRI) data collected while subjects listened to hours of narrative stories. We show that the mantic system is organized into intricate patterns that em to be consistent across individuals. We then u a novel generative model to create a detailed mantic atlas. Our results suggest that most areas within the mantic system reprent information about specific mantic domains, or groups of related concepts, and our atlas shows which domains are reprented in each area. This study demonstrates that data-driven methods—commonplace in studies of human neuroanatomy and functional connectivity—provide a powerful and efficient means for mapping functional reprentations in the brain.
