耳朵处声音的延迟（相位）和振幅的变化是分析声音运动的线索。这些线索的检测取决于输入到每只耳朵的会聚，这一过程首先发生在脑干中。对这些线索的有意识感知可能涉及更高的中心。使用新的刺激，产生不同的运动感知的存在下，相同的相位和振幅调制组件，我们已经证明了人类的大脑区域是活跃的，特别是在感知声音运动。功能性磁共振成像（fMRI）和正电子发射断层扫描（PET）表明，参与右顶叶皮层在声音运动知觉与这些刺激。
Changes in the delay (phase) and amplitude of sound at the ears are cues for the analysis of sound movement. The detection of these cues depends on the convergence of the inputs to each ear, a process that first occurs in the brainstem. The conscious perception of these cues is likely to involve higher centers. Using novel stimuli that produce different perceptions of movement in the presence of identical phase and amplitude modulation components, we have demonstrated human brain areas that are active specifically during the perception of sound movement. Both functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) demonstrated the involvement of the right parietal cortex in sound movement perception with these stimuli.
