研究目的:

本研究旨在可控压力平台上,系统比较不同气压压力水平(高压氧、等效低压)及其不同暴露节律(单次急性、连续慢性)对人体神经生理与认知功能的影响规律,明确压力作用的强度效应与时间效应。通过脑电、近红外、外周生理和行为学任务的同步观测,筛选对压力最敏感、可重复、可量化的多模态指标,构建“压力输入-中枢响应-行为输出”的一体化评价体系;进而为高原、深海和航空航天等极端环境下人员的选拔、训练与防护策略提供可直接应用的实验依据。  

Objectives of Study:

This study aims to systematically compare the effects of different barometric pressure levels (hyperbaric oxygen, equivalent hypobaric pressure) and their various exposure rhythms (single acute exposure, continuous chronic exposure) on human neurophysiological and cognitive functions on a controlled pressure platform, so as to clarify the intensity effect and time effect of pressure action. Through the synchronous observation of electroencephalography (EEG), near-infrared spectroscopy (NIRS), peripheral physiology, and behavioral tasks, we will screen sensitive, reproducible, and quantifiable multimodal indicators, and construct an integrated evaluation system of "pressure input - central response - behavioral output". Furthermore, it will provide directly applicable experimental basis for personnel selection, training, and protection strategies in extreme environments such as plateaus, deep seas, and aerospace.
