Recent case studies have suggested that emotion perception and emotional experience of music have independent cognitive processing. We report a patient who showed selective impairment of emotional experience only in listening to music, that is musical anhednia. A 71-year-old right-handed man developed an infarction in the right parietal lobe. He found himself unable to experience emotion in listening to music, even to which he had listened pleasantly before the illness. In neuropsychological assessments, his intellectual, memory, and constructional abilities were normal. Speech audiometry and recognition of environmental sounds were within normal limits. Neuromusicological assessments revealed no abnormality in the perception of elementary components of music, expression and emotion perception of music. Brain MRI identified the infarct lesion in the right inferior parietal lobule. These findings suggest that emotional experience of music could be selectively impaired without any disturbance of other musical, neuropsychological abilities. The right parietal lobe might participate in emotional experience in listening to music.
近期的病例研究表明，音乐的情感感知和情感体验具有独立的认知加工过程。我们报告了一位仅在听音乐时表现出情感体验选择性受损的患者，即音乐快感缺失。一名71岁的右利手男性右侧顶叶发生梗死。他发现自己无法在听音乐时体验到情感，即使是在患病前曾愉快聆听的音乐。在神经心理学评估中，他的智力、记忆力和建构能力均正常。言语听力测验和对环境声音的识别均在正常范围内。神经音乐学评估显示，音乐基本成分的感知、音乐的表达和情感感知均无异常。脑部磁共振成像（MRI）确定梗死病灶位于右侧顶下小叶。这些发现表明，音乐的情感体验可能会被选择性地损害，而不会干扰其他音乐、神经心理学能力。右侧顶叶可能参与了听音乐时的情感体验。
