Perceptual interpretation of the same multisensory stimuli may rely upon influence of attention on multisensory integration. We tested this hypothesis by recording the brain activity using magnetoencephalography in a passing-bouncing illusion with sound. Early activation of the attention-related brain areas and subsequent involvement of the multisensory areas were associated with the bouncing percept. Early activation of the unimodal sensory areas and later involvement of the attention-related areas were associated with the passing percept. Thus, the bouncing percept occurs when early attentional deployment facilitates multisensory integration modulating visual perception. The passing percept results from hierarchical sequence of the perceptual processes: early activation of the unimodal areas and late attentional deployment. Alternation of the perceptual interpretations may depend on spontaneous fluctuation of attention.
对相同多感官刺激的感知解释可能依赖于注意力对多感官整合的影响。我们通过在带有声音的通过-弹跳错觉中使用脑磁图记录大脑活动来检验这一假设。与注意力相关的脑区的早期激活以及随后多感官区域的参与与弹跳感知相关。单峰感觉区域的早期激活以及随后与注意力相关区域的参与与通过感知相关。因此，当早期注意力部署促进多感官整合调节视觉感知时，就会出现弹跳感知。通过感知是由感知过程的层次序列导致的：单峰区域的早期激活和后期注意力部署。感知解释的交替可能取决于注意力的自发波动。
