使用功能性磁神经成像（tMRI）和涉及扰乱音乐的独特刺激操纵来研究音乐结构的神经解剖学相关性。该实验比较了参与者听古典音乐和同一音乐的混音版本时的大脑反应。具体来说，扰乱的版本扰乱了音乐结构，同时保持低级音乐属性不变，包括音乐的心理声学特征，如音高、响度和音色。将音乐与其混乱的对应部分进行比较，我们发现左额下皮质的眼眶部区域（布罗德曼区域 47）有焦点激活，该区域以前与口语和手语中的语言结构处理及其右半球同源密切相关。我们推测，额下皮层的这个特定区域可能更普遍地负责处理随着时间的推移而演变的精细结构刺激，而不仅仅是那些语言刺激。 (C) 2003 Elsevier Inc. 保留所有权利。
The neuroanatomical correlates of musical structure were investigated using functional magnetic neuroimaging (tMRI) and a unique stimulus manipulation involving scrambled music. The experiment compared brain responses while participants listened to classical music and scrambled versions of that same music. Specifically, the scrambled versions disrupted musical structure while holding low-level musical attributes constant, including the psychoacoustic features of the music such as pitch, loudness, and timbre. Comparing music to its scrambled counterpart, we found focal activation in the pars orbitalis region (Brodmann Area 47) of the left inferior frontal cortex, a region that has been previously closely associated with the processing of linguistic structure in spoken and signed language, and its right hemisphere homologue. We speculate that this particular region of inferior frontal cortex may be more generally responsible for processing fine-structured stimuli that evolve over time, not merely those that are linguistic.
