Abstract：
A 62-year-old musician-MM-developed amusia after a right middle-cerebral-artery infarction. Initially, MM showed melodic deficits while discriminating pitch-related differences in melodies, musical memory problems, and impaired sensitivity to tonal structures, but normal pitch discrimination and spectral resolution thresholds, and normal cognitive and language abilities. His rhythmic processing was intact when pitch variations were removed. After 3 months, MM showed a large improvement in his sensitivity to tonality, but persistent melodic deficits and a decline in perceiving the metric structure of rhythmic sequences. We also found visual cues aided melodic processing, which is novel and beneficial for future rehabilitation practice.
摘要：
一位62岁的音乐家MM在右大脑中动脉梗塞后出现了失语症。最初，MM表现出旋律缺陷，同时区分旋律中与音高相关的差异，音乐记忆问题,对音调结构的敏感性受损，但是正常的音调辨别和光谱分辨率阈值，和正常的认知和语言能力。当音高变化被消除时，他的节奏处理是完整的。三个月后,MM对音调的敏感度有了很大的提高，但是持续的旋律缺陷和对节奏序列度量结构的感知下降。我们还发现视觉线索辅助旋律处理，这是新颖的，有利于未来的康复实践。
