At any given moment, we receive input through our different sensory systems, and this information needs to be processed and integrated. Multisensory processing requires the coordinated activity of distinct cortical areas. Key mechanisms implicated in these processes include local neural oscillations and functional connectivity between distant cortical areas. Evidence is now emerging that neural oscillations in distinct frequency bands reflect different mechanisms of multisensory processing. Moreover, studies suggest that aberrant neural oscillations contribute to multisensory processing deficits in clinical populations, such as schizophrenia. In this article, we review recent literature on the neural mechanisms underlying multisensory processing, focusing on neural oscillations. We derive a framework that summarizes findings on (1) stimulus-driven multisensory processing, (2) the influence of top-down information on multisensory processing, and (3) the role of predictions for the formation of multisensory perception. We propose that different frequency band oscillations subserve complementary mechanisms of multisensory processing. These processes can act in parallel and are essential for multisensory processing.

在任何特定时刻，我们都会通过不同的感觉系统接收输入，并且需要对这些信息进行处理和整合。多感官处理需要不同皮质区域的协调活动。这些过程中涉及的关键机制包括局部神经振荡和远处皮质区域之间的功能连接。现在有证据表明，不同频段的神经振荡反映了多感官处理的不同机制。此外，研究表明，异常的神经振荡会导致临床人群的多感觉处理缺陷，例如精神分裂症。在本文中，我们回顾了有关多感觉处理神经机制的最新文献，重点关注神经振荡。我们得出了一个框架，总结了以下方面的发现：（1）刺激驱动的多感官处理，（2）自上而下的信息对多感官处理的影响，以及（3）预测对多感官知觉形成的作用。我们提出不同频带振荡有助于多感官处理的互补机制。这些过程可以并行进行，对于多感官处理至关重要。
