本研究通过与事件相关的功能磁共振成像（fMRI）研究了听觉拟声处理对血氧水平依赖性的反应。我们使用了一个声音分类任务，在这个任务中，参与者听到四种类型的刺激：拟声、名词（口头）、动物（非口头）声音和纯音/噪音（对照）。通过区分目标声音类别（鸟类/非鸟类），名词引起左侧颞前上回（STG）的激活，而动物声音引起双侧颞上沟（STS）和左侧额下回（IFG）的激活。相比之下，拟声词激活了广泛的大脑区域，包括左前侧STG，从双侧STS到颞中回的区域，以及双侧IFG。拟声词比名词和环境音在右侧中间STS中表现出更大的激活。这些结果表明，拟声声音是由涉及语言和非语言声音处理的广泛的大脑区域处理的。因此，我们可以假设拟声可以作为名词和动物声音之间的桥梁。这是第一个证明人类大脑处理拟声方式的证据。(c) 2006爱思唯尔公司版权所有。
This event-related fMRI study was conducted to examine the blood-oxygen-level-dependent responses to the processing of auditory onomatopoeic sounds. We used a sound categorization task in which the participants heard four types of stimuli: onomatopoeic sounds, nouns (verbal), animal (nonverbal) sounds, and pure tone/noise (control). By discriminating between the categories of target sounds (birds/nonbirds), the nouns resulted in activations in the left anterior superior temporal gyrus (STG), whereas the animal sounds resulted in activations in the bilateral superior temporal sulcus (STS) and the left inferior frontal gyrus (IFG). In contrast, the onomatopoeias activated extensive brain regions, including the left anterior STG, the region from the bilateral STS to the middle temporal gyrus, and the bilateral IFG. The onomatopoeic sounds showed greater activation in the right middle STS than did the nouns and environmental sounds. These results indicate that onomatopoeic sounds are processed by extensive brain regions involved in the processing of both verbal and nonverbal sounds. Thus, we can posit that onomatopoeic sounds can serve as a bridge between nouns and animal sounds. This is the first evidence to demonstrate the way in which onomatopoeic sounds are processed in the human brain. (c) 2006 Elsevier Inc. All rights reserved.
