目的神经损伤患者的词汇（名称）和概念（语义）信息检索经常受到损害。经常受到影响的一类物品是乐器。然而，乐器的词汇和概念知识背后的独特神经解剖学相关性尚未确定。方法我们使用神经心理学方法来探索乐器知识检索的神经相关性。大量患有局灶性脑损伤的个体（N = 298）观看了 16 种乐器的图片，并被要求说出每种乐器的名称和标识。采用比例 MAP-3 方法分析神经解剖数据，以创建体素病变比例差异图。结果乐器命名（词汇检索）受损与左颞极和下中央前后回损伤相关。乐器识别（概念知识检索）受损与更广泛和双边分布的区域网络相关，包括腹内侧前额皮质、枕叶皮质和颞上回。结论这些发现扩展了我们对乐器在神经系统水平上如何处理的理解，并阐明了可能解释为什么脑损伤可能会或可能不会产生乐器失认症或失认症的因素。我们的发现还有助于更广泛地理解大脑中与类别相关的知识图谱，因为乐器具有与其他各种类别的物品相似的几个特征：它们是无生命的且高度可操作的（类似于工具），产生特征声音（类似于动物），并且需要彼此之间进行细粒度的视觉区分（类似于人）。（PsycINFO数据库记录（c）2019 APA，保留所有权利）
ObjectiveRetrieval of lexical (names) and conceptual (semantic) information is frequently impaired in individuals with neurological damage. One category of items that is often affected is musical instruments. However, distinct neuroanatomical correlates underlying lexical and conceptual knowledge for musical instruments have not been identified.MethodWe used a neuropsychological approach to explore the neural correlates of knowledge retrieval for musical instruments. A large sample of individuals with focal brain damage (N= 298), viewed pictures of 16 musical instruments and were asked to name and identify each instrument. Neuroanatomical data were analyzed with a proportional MAP-3 method to create voxelwise lesion proportion difference maps.ResultsImpaired naming (lexical retrieval) of musical instruments was associated with damage to the left temporal pole and inferior pre-and postcentral gyri. Impaired recognition (conceptual knowledge retrieval) of musical instruments was associated with a more broadly and bilaterally distributed network of regions, including ventromedial prefrontal cortices, occipital cortices, and superior temporal gyrus.ConclusionsThe findings extend our understanding of how musical instruments are processed at neural system level, and elucidate factors that may explain why brain damage may or may not produce anomia or agnosia for musical instruments. Our findings also help inform broader understanding of category-related knowledge mapping in the brain, as musical instruments possess several characteristics that are similar to various other categories of items: They are inanimate and highly manipulable (similar to tools), produce characteristic sounds (similar to animals), and require fine-grained visual differentiation between each other (similar to people).(PsycINFO Database Record (c) 2019 APA, all rights reserved)
