关于人类神经系统对语言处理和学习的贡献的研究通常集中在大脑的关联区域，而不考虑主要和邻近感觉区域的可能贡献。我们报告了一项研究，检查赫施尔回 (HG) 的解剖结构之间的关系，该回主要包括初级听觉区域，并且通常被发现与非语言音高处理和语言学习相关。与英语不同，世界上大多数语言都使用音高模式来表示单词含义。在本研究中，以英语为母语的成人受试者学会了将外来语调模式纳入单词识别中。与成功的学习者相比，学习不太成功的受试者左侧的 HG 体积（尤其是灰质体积）较小，但右侧则不然。这些结果表明，HG 通常与非语音处理中的声学线索处理相关，但它也参与语音学习。这些结果还表明，初级听觉区域对于口语学习过程中基本声音线索的编码可能很重要。
Research on the contributions of the human nervous system to language processing and learning has generally been focused on the association regions of the brain without considering the possible contribution of primary and adjacent sensory areas. We report a study examining the relationship between the anatomy of Heschl's Gyrus (HG), which includes predominately primary auditory areas and is often found to be associated with nonlinguistic pitch processing and language learning. Unlike English, most languages of the world use pitch patterns to signal word meaning. In the present study, native English-speaking adult subjects learned to incorporate foreign pitch patterns in word identification. Subjects who were less successful in learning showed a smaller HG volume on the left (especially gray matter volume), but not on the right, relative to learners who were successful. These results suggest that HG, typically shown to be associated with the processing of acoustic cues in nonspeech processing, is also involved in speech learning. These results also suggest that primary auditory regions may be important for encoding basic acoustic cues during the course of spoken language learning.
