有些词会立即自动地让我们联想到气味，而其他语言项目则不会引起这种联想。这项研究首次使用现代神经成像技术（功能性MRI）研究了语言和气味信息的抽象联系。受试者被动阅读气味相关的词（“大蒜”，“肉桂”，“茉莉”）和中性语言项目。与气味相关的词语会激活初级嗅觉皮层，包括梨状皮层和杏仁核。Pur的结果表明，广泛分布的皮层细胞组件的激活在处理嗅觉的话。这些分布的神经元群延伸到语言区域，但也到达嗅觉系统的某些部分。这些分布的神经系统可能是处理语言元素及其相关概念和语义信息以及相关感觉信息的基础。(c)2006年爱思唯尔公司All rights reserved.
Some words immediately and automatically remind us of odours, smells and scents, whereas other language items do not evoke such associations. This study investigated, for the first time, the abstract linking of linguistic and odour information using modern neuro-imaging techniques (functional MRI). Subjects passively read odour-related words ('garlic', 'cinnamon', 'jasmine') and neutral language items. The odour-related terms elicited activation in the primary olfactory cortex, which include the piriform cortex and the amygdala. Pur results suggest the activation of widely distributed cortical cell assemblies in the processing of olfactory words. These distributed neuron populations extend into language areas but also reach some parts of the olfactory system. These distributed neural systems may be the basis of the processing of language elements, their related conceptual and semantic information and the associated sensory information.
