Visuomanual prism adaptation (PA), which consists of pointing to visual targets while wearing prisms that shift the visual field, is one of the oldest experimental paradigms used to investigate sensorimotor plasticity. Since the 2000's, a growing scientific interest emerged for the expansion of PA to cognitive functions in several sensory modalities. The present work focused on the aftereffects of PA within the auditory modality. Recent studies showed changes in mental representation of auditory frequencies and a shift of divided auditory attention following PA. Moreover, one study demonstrated benefits of PA in a patient suffering from tinnitus. According to these results, we tried to shed light on the following question: How could this be possible to modulate audition by inducing sensorimotor plasticity with glasses? Based on the literature, we suggest a bottom-up attentional mechanism involving cerebellar, parietal, and temporal structures to explain crossmodal aftereffects of PA. This review opens promising new avenues of research about aftereffects of PA in audition and its implication in the therapeutic field of auditory troubles.
视动性手镜适应（PA），即通过佩戴使视野发生位移的棱镜来指向视觉目标，是用于研究感觉运动可塑性的最古老的实验范例之一。自 21 世纪初以来，人们对将 PA 扩展到多种感觉模态的认知功能产生了越来越浓厚的兴趣。本研究主要关注听觉模态中的 PA 后效。最近的研究表明，在 PA 之后听觉频率的心理表征发生了变化，并且听觉注意力也发生了分散。此外，有一项研究表明 PA 对耳鸣患者有益。根据这些结果，我们试图探讨以下问题：通过使用眼镜诱导感觉运动可塑性，怎么可能调节听觉？基于文献，我们提出了一个自下而上的注意机制，该机制涉及小脑、顶叶和颞叶结构，以解释 PA 的跨模态后效。这篇综述为 PA 在听觉中的后效及其在听觉障碍治疗领域的应用开辟了有前景的新研究途径。
