本研究采用功能磁共振成像技术对音乐知觉的神经功能进行了研究。三个不同的主题组进行了调查，以研究音乐训练的发展方面和影响：10岁的儿童不同程度的音乐训练，成年人没有正式的音乐训练（nonmusicians），和成人音乐家。受试者作出判断的序列，结束的和弦，音乐句法要么规则或不规则。在成年人中，不规则的弦激活额下回、眶额外侧皮质、前额叶、腹外侧运动前皮质、上级颞回的前部和后部、上级颞沟和缘上回。这些结构可能形成不同的网络，介导音乐处理的认知方面（如音乐句法和音乐意义的处理，以及听觉工作记忆），以及音乐处理的情感方面。在右半球，儿童的激活模式与成人相似。在左半球，成年人在前额区、缘上回和颞区的激活比儿童大。在成人和儿童中，音乐训练与额盖和上级颞回前部的较强激活相关。(c)2005年爱思唯尔公司All rights reserved.
The present study investigates the functional neuroanatomy of music perception with functional magnetic resonance imaging (fMRI). Three different subject groups were investigated to examine developmental aspects and effects of musical training: 10-year-old children with varying degrees of musical training, adults without formal musical training (nonmusicians), and adult musicians. Subjects made judgements on sequences that ended on chords that were music-syntactically either regular or irregular. In adults, irregular chords activated the inferior frontal gyrus, orbital frontolateral cortex, the anterior insula, ventrolateral premotor cortex, anterior and posterior areas of the superior temporal gyrus, the superior temporal sulcus, and the supramarginal gyrus. These structures presumably form different networks mediating cognitive aspects of music processing (such as processing of musical syntax and musical meaning, as well as auditory working memory), and possibly emotional aspects of music processing. In the right hemisphere, the activation pattern of children was similar to that of adults. In the left hemisphere, adults showed larger activations than children in prefrontal areas, in the supramarginal gyrus, and in temporal areas. In both adults and children, musical training was correlated with stronger activations in the frontal operculum and the anterior portion of the superior temporal gyrus. (c) 2005 Elsevier Inc.
