摘　　要：警觉度是人体长时间保持注意力或警惕性的能力。自20世纪中叶以来,随着人机交流的显著增加,驾驶安全、医疗、航空航天和军事等重要领域均对工作人员的警觉度水平提出了较高要求。因此,探索快速提高警觉度的方法成为医学领域的研究热点和亟需解决的重大课题。本文以物理调节、化学调节和生理调节三大角度为出发点,介绍了提高大脑警觉度方法的最新进展,并对其发展动态进行展望,同时也为寻求更加有效、方便地提高大脑警觉度的方法提出了设想。Vigilance is defined as the ability to maintain attention or alertness over prolonged periods of time. Since Mid-2Oth century, following the increasing man-machine communication, high level of vigilance has been demanded in many areas including driving safety, medical care and therapy, aerospace and military affairs, etc. Therefore, finding quick methods to improve the level of vigilance has become a key issue in medical study. Based on physical regulation, chemical regulation and physiological regulation, the research progress has been summarized in this paper. We, furthermore, also try to predict the future trend in this academic area and develop some tentative ideas about seeking more effective and convenient ways to improve the level of brain vigilance.
