In a recent article, N. Bien, S. ten Oever, R. Goebel, and A. T. Sack (2012) used event-related potentials to investigate the consequences of crossmodal correspondences (the "natural" mapping of features, or dimensions, of experience across sensory modalities) on the time course of neural information processing. Then, by selectively lesioning the right intraparietal cortex using transcranial magnetic stimulation, these researchers went on to demonstrate (for the first time) that it is possible to temporarily eliminate the effect of crossmodal congruency on multisensory integration (specifically on the spatial ventriloquism effect). These results are especially exciting given the possibility that the cognitive neuroscience methodology utilized by Bien et al. (2012) holds for dissociating between putatively different kinds of crossmodal correspondence in future research.
在最近的一篇文章中，N. 比恩、S. 滕·奥弗、R. 戈贝尔和A. T. 萨克（2012年）运用事件相关电位来研究跨通道对应关系（即经验的特征或维度在不同感觉通道间的“自然”映射）对神经信息处理时间进程的影响。接着，通过经颅磁刺激选择性损伤右侧顶内沟皮层，这些研究人员进而（首次）证明，有可能暂时消除跨通道一致性对多感觉整合（特别是对空间视错觉效应）的影响。鉴于比恩等人（2012年）所采用的认知神经科学方法在未来研究中有可能用于区分假定不同类型的跨通道对应关系，这些结果尤其令人兴奋。
