The brain encodes sight, sound and touch separately yet our perception is coherent and multisensory. How the brain achieves this is puzzling for it faces a major problem: each sense has a different temporal latency and maps space in different coordinates. Exploiting a new method that revealed a very fast temporal realignment process, this project examines relative timing between touch, vision and hearing and their interaction with motor action to reveal the full scope of sensory and motor recalibration. By determining the spatial coordinates in which recalibration occurs, and examining interactions between on-going temporal modulations once aligned, this project aims to advance knowledge of multisensory integration.

大脑分别编码视觉、声音和触觉，但我们的感知是连贯的和多感官的。大脑如何做到这一点是令人困惑的，因为它面临着一个主要问题：每种感觉都有不同的时间延迟，并以不同的坐标映射空间。利用一种新的方法，揭示了一个非常快的时间重新校准过程，该项目研究了触觉，视觉和听觉之间的相对时间以及它们与运动动作的相互作用，以揭示感官和运动重新校准的全部范围。通过确定重新校准发生的空间坐标，并检查正在进行的时间调制之间的相互作用，一旦对齐，该项目旨在推进多感官整合的知识。
