Multisensory integration during self-motion perception

当我们在复杂的环境中移动时，我们的大脑必须有效地整合来自视觉、肌肉和关节（本体感觉）以及内耳（前庭）中的加速度检测器的信息。这些感觉和运动输入的最佳整合使我们能够更确定地估计运动参数，如速度，距离和航向。传统上，这些感觉系统中的每一个都是独立研究的，但这项研究计划的目的是量化这些多个感觉输入在自我运动过程中如何整合到大脑中。拟议的研究计划的目标将是经验性地评估既定的多感觉整合的原则，以及引入新的实验操作，旨在更好地表征视觉，本体感受和前庭整合在自我运动感知。具体而言，其目的是：

As we move through complex environments, our brain must effectively integrate information from vision, muscles and joints (proprioception), and the acceleration detectors in the inner ear (vestibular). An optimal integration of these sensory and motor inputs allows us to estimate movement parameters such as speed, distance, and heading direction with greater certainty. Traditionally, each of these sensory systems has been studied independently of one another, but this research program is aimed at quantifying how these multiple sensory inputs are integrated in the brain during self-motion. The objectives of the proposed research program will be to empirically evaluate established tenets of multisensory integration, as well as to introduce novel experimental manipulations aimed at better characterizing visual, proprioceptive, and vestibular integration during self-motion perception. Specifically it aims to:
