我们已经提出，左下颞（IT）区域包含的结构，概念知识检索和单词形式检索之间的调解，我们假设，这些结构被用于单词检索，而不管的感觉方式，通过该实体被理解，因此是“模态中性”。我们测试了这一想法在两个感官形式，视觉和听觉，并为两类具体的实体，工具和动物。在PET实验中，10名正常参与者从图片或特征声音（例如，“scissors”来自剪刀的图片或来自剪刀剪切的声音;“rooster”来自公鸡的图片或来自公鸡的啼叫声）。视觉和听觉命名的工具激活左后/外侧IT;视觉和听觉命名的动物激活左前/腹侧IT。对于工具和动物，左侧IT激活的位置和幅度相似，无论参与者是否从图片或声音命名实体。结果提供了新的证据来支持的概念，左IT结构包含“模态中立”的概念知识和词检索之间的调解系统。
We have proposed that the left inferotemporal (IT) region contains structures that mediate between conceptual knowledge retrieval and word-form retrieval, and we have hypothesized that these structures are utilized for word retrieval irrespective of the sensory modality through which an entity is apprehended, thus being “modality neutral.” We tested this idea in two sensory modalities, visual and auditory, and for two categories of concrete entities, tools and animals. In a PET experiment, 10 normal participants named tools and animals either from pictures or from characteristic sounds (e.g., “scissors” from a picture of a scissors or from the sound of a scissors cutting; “rooster” from a picture of a rooster or from the sound of a rooster crowing). Visual and auditory naming of tools activated the left posterior/lateral IT; visual and auditory naming of animals activated the left anterior/ ventral IT. For both tools and animals, the left IT activations were similar in location and magnitude regardless of whether participants were naming entities from pictures or from sounds. The results provide novel evidence to support the notion that left IT structures contain “modality-neutral” systems for mediating between conceptual knowledge and word retrieval.
