Theories of reading have posited the existence of a neural representation coding for whole real words (i.e., an orthographic lexicon), but experimental support for such a representation has proved elusive. Using fMRI rapid adaptation techniques, we provide evidence that the human left ventral occipitotemporal cortex (specifically the "visual word form area," VWFA) contains a representation based on neurons highly selective for individual real words, in contrast to current theories that posit a sublexical representation in the VWFA.
阅读理论假定存在一种对整个真实单词进行编码的神经表征（即正字法词汇表），但对这种表征的实验支持却难以获得。利用功能磁共振成像快速适应技术，我们提供了证据表明，人类左腹侧枕颞叶皮层（特别是“视觉词形区”，VWFA）包含一种基于对单个真实单词具有高度选择性的神经元的表征，这与当前认为VWFA中存在亚词汇表征的理论形成对比。
