The perception of the music in cochlear implanted (CI) patients is an important aspect of their quality of life. In fact, the pleasantness of the music perception by such CI patients can be analyzed through a particular analysis of EEG rhythms. Studies on healthy subjects show that exists a particular frontal asymmetry of the EEG alpha rhythm which can be correlated with pleasantness of the perceived stimuli (approach-withdrawal theory). In particular, here we describe differences between EEG activities estimated in the alpha frequency band for a monolateral CI group of children and a normal hearing one during the fruition of a musical cartoon. The results of the present analysis showed that the alpha EEG asymmetry patterns related to the normal hearing group refers to a higher pleasantness perception when compared to the cerebral activity of the monolateral CI patients. In fact, the present results support the statement that a monolateral CI group could perceive the music in a less pleasant way when compared to normal hearing children.
人工耳蜗植入（CI）患者对音乐的感知是其生活质量的一个重要方面。事实上，此类人工耳蜗植入患者对音乐感知的愉悦程度可通过对脑电图节律的特定分析来进行剖析。针对健康受试者的研究表明，脑电图α节律存在特定的额叶不对称性，这可能与所感知刺激的愉悦程度相关（趋近 - 回避理论）。具体而言，在此我们描述了在观看音乐卡通片期间，单侧人工耳蜗植入儿童组和正常听力儿童组在α频段估计的脑电图活动之间的差异。当前分析结果显示，与单侧人工耳蜗植入患者的大脑活动相比，正常听力组相关的α脑电图不对称模式表明其具有更高的愉悦感。实际上，当前结果支持这样一种说法，即与正常听力儿童相比，单侧人工耳蜗植入组对音乐的感知方式可能不那么愉悦。
