Understanding how sensory pathways transmit information under natural conditions remains a major goal in neuroscience. The vestibular system plays a vital role in everyday life, contributing to a wide range of functions from reflexes to the highest levels of voluntary behavior. Recent experiments establishing that vestibular (self-motion) processing is inherently multimodal also provide insight into a set of interrelated questions. What neural code is used to represent sensory information in vestibular pathways? How do the interactions between the organism and the environment shape encoding? How is self-motion information processing adjusted to meet the needs of specific tasks? This review highlights progress that has recently been made towards understanding how the brain encodes and processes self-motion to ensure accurate motor control.
了解感觉通路在自然条件下如何传递信息仍然是神经科学的主要目标。前庭系统在日常生活中起着至关重要的作用,有助于从反射到最高水平的自愿行为等广泛的功能。最近的实验表明,前庭(自身运动)处理本质上是多模式的,这也为一系列相互关联的问题提供了深入了解。用于在前庭通路中表示感觉信息的神经代码是什么?生物体与环境之间的相互作用如何影响编码?如何调整自身运动信息处理以满足特定任务的需求?本综述强调了最近在理解大脑如何对自身运动进行编码和处理以确保精确的运动控制方面取得的进展。
