Previous work has investigated extensively the neuroanatomical correlates of lexical retrieval for words for concrete entities. Musical entities, such as musical instruments, are often included in studies of category-specific naming deficits, but have rarely been the focus of such work.
This article reviews a program of research investigating the neuroanatomical basis for lexical retrieval of words for unique (i.e., melodies) and non-unique (i.e., musical instruments) musical entities.
We begin by reporting findings on the retrieval of words for unique musical entities, including musical melodies. We then consider work focusing on retrieval of words for non-unique musical entities, specifically musical instruments. We highlight similarities between the two lines of work, and then report results from new analyses including direct comparisons between the two. These comparisons suggest that impairments in naming musical melodies and in naming musical instruments are both associated with damage to the left temporal pole (LTP). However, musical instrument naming appears to rely on a more distributed set of brain regions, possibly including those relating to sensorimotor interactions with such instruments, whereas melody naming relies more exclusively on the left temporal pole.
Retrieval of names for musical melodies appears to rely on similar neuroanatomical correlates as for other proper nouns, namely the LTP. Musical instrument naming seems to rely on a broader network of regions, including the LTP and sensorimotor areas. Overall, melody naming seems to coincide with naming of other proper nouns, while musical instrument naming appears distinct from other categories of non-unique items.
先前的研究广泛探讨了具体实体词汇检索的神经解剖学关联。音乐实体,如乐器,经常被纳入特定类别命名缺陷的研究中,但很少成为此类研究的重点。
本文回顾了一项研究计划,该计划旨在探究独特(即旋律)和非独特(即乐器)音乐实体词汇检索的神经解剖学基础。
我们首先报告关于独特音乐实体(包括音乐旋律)词汇检索的研究结果。然后我们考虑聚焦于非独特音乐实体(特别是乐器)词汇检索的研究。我们强调这两条研究路线之间的相似性,接着报告新分析的结果,包括两者之间的直接比较。这些比较表明,命名音乐旋律和命名乐器的障碍均与左侧颞极(LTP)损伤有关。然而,乐器命名似乎依赖于更广泛分布的一组脑区,可能包括与这些乐器进行感觉运动交互相关的脑区,而旋律命名则更专门地依赖于左侧颞极。
音乐旋律名称的检索似乎依赖于与其他专有名词类似的神经解剖学关联,即左侧颞极。乐器命名似乎依赖于更广泛的脑区网络,包括左侧颞极和感觉运动区域。总体而言,旋律命名似乎与其他专有名词的命名一致,而乐器命名似乎与其他类别非独特项目的命名不同。
