姿势的神经机制综述

A Review of the Neural Mechanisms of Posture

当今的脑成像研究一般采取与日常生活不同的姿势(posture),而姿势会影响人们的神经活动和认知表现。人们工作时通常采用坐立或站立的直立姿势,而在神经成像实验中,大多要求被试保持一个静止非生态的姿势,并且待在密闭空间的实验室中。生态姿势和成像姿势之间存在不一致,导致许多神经成像结论的推广性受到了限制。本综述回顾了姿势对认知、生理和睡眠造成的影响,探讨了姿势对脑成像数据造成影响的潜在机制,并展望了相应的解决思路。

Current brain imaging studies generally use different postures with the daily life, but posture may influence the human neural activity and cognitive performance. People are usually sitting or standing in an upright posture when they work, while requiring most of the subjects keep still and non-ecology posture in a confined-space laboratory room when they participate in neuroimaging experiments. This inconsistency between the ecological posture and imaging posture results in the limitation of generalization of neuroimaging findings. This paper reviewed posture impact on cognition, physiology, and sleep, then the underlying mechanisms that posture affects brain imaging data was discussed and the corresponding solution was provided.
