更高水平的话语处理唤起了认知模式和大脑激活，超出了句子的字面理解。我们使用功能磁共振成像来检查大脑激活模式，同时16名健康参与者阅读简短的三句话故事，这些故事以字面，隐喻或讽刺的句子结束。在阅读关键句的过程中获得的fMRI图像显示了大脑对两种非文字话语的选择性反应。隐喻性话语的左侧额下回和双侧颞叶下皮层的激活水平显著高于字面和讽刺性话语。在右颞中回和右上级，讽刺性的语句导致显着较高的激活水平比文字语句，与隐喻性的语句导致在这些地区的中间水平。研究结果表明，这些方面的比喻语言的差异半球的敏感性，并有关模型的功能性皮层架构的语言处理连接的话语。(c)2006爱思唯尔有限公司保留所有权利。
Higher levels of discourse processing evoke patterns of cognition and brain activation that extend beyond the literal comprehension of sentences. We used fMRI to examine brain activation patterns while 16 healthy participants read brief three-sentence stories that concluded with either a literal, metaphoric, or ironic sentence. The fMRI images acquired during the reading of the critical sentence revealed a selective response of the brain to the two types of nonliteral utterances. Metaphoric utterances resulted in significantly higher levels of activation in the left inferior frontal gyrus and in bilateral inferior temporal cortex than the literal and ironic utterances. Ironic statements resulted in significantly higher activation levels than literal statements in the right superior and middle temporal gyri, with metaphoric statements resulting in intermediate levels in these regions. The findings show differential hemispheric sensitivity to these aspects of figurative language, and are relevant to models of the functional cortical architecture of language processing in connected discourse.
