在众多神经影像学和临床研究中已经研究了语义记忆，其中大多数使用了视觉言语，但是很少有音乐材料临床研究表明，在本研究中，言语和音乐语义记忆之间存在相对的神经独立性，在本研究中， “音乐语义记忆”被定义为“知名”旋律的记忆在不了解学习的空间或时间环境的情况下，我们的目标是通过在每种方式中管理相同类型的任务来比较音乐和言语语义记忆的神经底物，我们使用高分辨率的PET H2O15来观察11个主要受试者，他们执行两个主要受试者任务（1）音乐语义记忆任务。受试者听到熟悉旋律的第一部分，并且必须决定他们听到的第二部分是否与第一个相匹配，以及（2）具有相同设计的口头语义记忆任务，但材料由众所周知的表达方式或谚语组成。音乐语义记忆条件激活了左半球的上等时间区域，下半球的下部和中间区域，右半球的下部额叶区域。言语语义记忆条件激活了左半球的中间时间区域和战斗半球的小脑。我们发现，口头和音乐语义过程激活了一个通用网络，该网络延伸到整个左颞新皮层，此外，该网络中还有一个依赖物质的地形偏好，在音乐任务期间主要是前验激活，并且在语义言语任务期间主要是后验激活（ C）2009 Elsevier Inc保留所有权利
Semantic memory has been investigated in numerous neuroimaging and clinical studies, most of which have used verbal Of Visual, but only very seldom, musical material Clinical Studies have suggested that there is a relative neural independence between verbal and Musical semantic memory In the present study, "Musical semantic memory" is defined as memory for "well-known" melodies Without any knowledge of the spatial or temporal circumstances of learning, while "verbal semantic memory" corresponds to general knowledge about concepts, again without any knowledge of the spatial or temporal circumstances of learning Our aim was to compare the neural substrates of musical and verbal semantic memory by administering the same type of task in each modality We used high-resolution PET H2O15 to observe 11 young subjects performing two main tasks (1) a musical semantic memory task. where the subjects heard the first part of familiar melodies and had to decide whether the second part they heard matched the first, and (2) a verbal semantic memory task with the same design, but where the material consisted of well-known expressions or proverbs. The musical semantic memory condition activated the superior temporal area and inferior and middle frontal areas in the left hemisphere and the inferior frontal area in the right hemisphere. The verbal semantic memory condition activated the middle temporal region in the left hemisphere and the cerebellum in the fight hemisphere. We found that the verbal and musical semantic processes activated a common network extending throughout the left temporal neocortex In addition, there was a material-dependent topographical preference within this network, with predominantly anterior activation during musical tasks and predominantly posterior activation during semantic verbal tasks (C) 2009 Elsevier Inc All rights reserved
