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.
利用功能磁共振成像技术，确定了与感叹词感知处理相关的脑血流动力学反应分布（感叹词即“插入话语中但与该话语无语法联系的感叹语”），并与无声基线条件进行了对比。这些话语通过其“语调”（情感韵律）和/或词汇内容传达有关说话者情感/情绪状态的信息。感叹词的这两个交际方面均在颞上叶皮质内引发了显著的双侧血氧水平依赖性信号变化。此外，情感韵律线索还引起了脑岛后部以及参与先天情绪行为控制的皮质/皮质下结构的血流动力学激活。这些观察结果证实了以下观点，即感叹词可能追溯到语言进化早期的原始言语发声。
