使用功能性磁共振成像，确定了与感叹词的感知处理相关的血液动力学脑反应的分布，即插入到话语中而没有语法连接的感叹词（与沉默的基线条件相比）。这些话语通过它们的“语气”（情感韵律）和/或它们的词汇内容来传达关于说话者的情感/情绪状态的信息。两个交流方面的感叹词引起显着的双边血氧水平依赖的信号变化，在上级颞叶皮层。此外，情感韵律线索产生血液动力学激活的后额叶皮层以及皮质/皮质下结构参与控制先天的情绪行为。这些观察结果证实了感叹词可能追溯到语言进化早期阶段的原始语音发声的建议。NeuroReport 19：1751-1755（C）2008 Wolters Kluwer Health vertical bar Lippincott威廉姆斯& Wilkins.
Using functional magnetic resonance imaging, the distribution of hemodynamic brain responses bound to the perceptual processing of interjections, that is 'exclamations inserted into an utterance without grammatical connection to it, was determined (vs. a silent baseline condition). These utterances convey information about a speaker's affective/emotional state by their 'tone' (emotional prosody) and/or their lexical content. Both communicative aspects of interjections elicited significant bilateral blood-oxygen-level-dependent signal changes within superior temporal cortex. In addition, affective-prosodic cues yielded hemodynamic activation of the posterior insula as well as cortical/subcortical structures engaged in the control of innate emotional behavior. These observations corroborate the suggestion that interjections might trace back to proto-speech vocalizations of an early stage of language evolution.
