本实验旨在利用脑磁图（MEG）定位处理音乐-句法不一致的神经基质。电，这样的处理已被提出表示为早期右前负性（ERAN），这是引起了和谐不适当的和弦发生在一个大小调的音调背景。在本实验中，这种和弦引起了早期效应，被视为ERAN的磁性等价物（称为mERAN）。MERAN活动的来源位于布罗卡区及其右半球同源区，这些区域在听觉语言理解过程中参与句法分析。我们发现，这些地区也负责传入的谐波序列的分析，表明这些地区的处理句法信息，是语言特异性比以前认为的。
The present experiment was designed to localize the neural substrates that process music-syntactic incongruities, using magnetoencephalography (MEG). Electrically, such processing has been proposed to be indicated by early right-anterior negativity (ERAN), which is elicited by harmonically inappropriate chords occurring within a major-minor tonal context. In the present experiment, such chords elicited an early effect, taken as the magnetic equivalent of the ERAN (termed mERAN). The source of mERAN activity was localized in Broca's area and its right-hemisphere homologue, areas involved in syntactic analysis during auditory language comprehension. We find that these areas are also responsible for an analysis of incoming harmonic sequences, indicating that these regions process syntactic information that is less language-specific than previously believed.
