我们报告的情况下，一个65岁的男子WDK，谁经历了选择性的损失，键盘和打击乐器的音色知觉右颞中风后，包括前上级和内侧回和岛区的一部分。以前是一个狂热的音乐听众，管弦乐队的声音似乎是“单位”给他。WDK和一个匹配的对照受试者进行了详细的神经心理学测试电池，包括基本的听觉功能（听力和音高变化的显着差异），特定的听觉功能（识别环境声音），特定的音乐功能，如音高，间隔，轮廓，节奏和节拍的歧视，熟悉的旋律，情感反应，感知音色和听觉频谱分析。虽然WDK显示没有缺陷的主要听觉功能，测试电池显示在键盘和打击乐器的音色，这可以追溯到一个赤字的歧视快速变化的频谱组成的音调的感知选择性损害。因此，这些研究结果表明，在右前颞叶的音色感知的孤立方面的高度特定的神经网络的存在。
We report the case of a 65-year-old man WDK, who experienced selective loss of timbre perception for keyboard and percussion instruments following a right temporal stroke comprising the anterior superior and medial gyrus and parts of the insular region. Formerly an avid listener to music, the sound of an orchestra appeared to be "flat" to him. WDK and a matched control subject underwent a detailed neuropsychological test battery covering basic auditory function (audiometry and just notable difference for pitch shifts), specific auditory function (recognition of environmental sounds), specific musical functions like discrimination of pitch, interval, contour, rhythm and metre, recognition of familiar melodies, emotional responsiveness, perception of timbre and auditory spectral analysis. While WDK displayed no deficits in primary auditory function, the test battery revealed a selective impairment in the perception of timbre of keyboard and percussion instruments which could be traced to a deficit in discriminating rapid changes of the spectral composition of a tone. Hence, these findings demonstrate the existence of highly specific neural networks underlying isolated aspects of timbre perception in the right anterior temporal lobe.
