音节和音位是语音结构中的两个重要单位。在大脑绘图的文献中，是否有单独的大脑区域介导音节和音素的处理仍然没有解决。利用功能磁共振成像（fMRI），我们研究了这些语音单位的神经基质与中国人。结果表明，左侧额叶中回参与音节加工，而左侧前额叶下回参与音素加工。这种模式的研究结果提供了令人信服的证据，不同的皮质区相关的音节和音素的代表。Hum.脑图谱18：201-207，2003年。© 2003 Wiley利斯公司
The syllable and the phoneme are two important units in the phonological structure of speech sounds. In the brain mapping literature, it remains unsolved as to whether there are separate brain regions mediating the processing of syllables and phonemes. Using functional magnetic resonance imaging (fMRI), we investigated the neural substrate of these phonological units with Chinese subjects. Results revealed that the left middle frontal cortex contributes to syllabic processing, whereas the left inferior prefrontal gyri contributes to phonemic processing. This pattern of findings offers compelling evidence for distinct cortical areas relevant to the representation of syllables and phonemes. Hum. Brain Mapping 18:201–207, 2003. © 2003 Wiley‐Liss, Inc.
