摘　　要：探讨吸入天然复方芳香精油对于健康人群认知功能的影响及其可能的神经机制。通过选择健康大学生被试,随机分为有精油吸入组和无精油吸入组,被试需完成注意力、短时记忆与计算能力3个认知任务,采用64通道脑电设备记录被试任务过程中事件相关电位的变化。结果表明,精油吸入条件下,被试在完成注意任务时,注意力水平有所提升,P3、Oz、C4等通道P300波幅出现显著差异,但短时记忆与计算能力则没有出现显著差异。Forty-two college students were divided into treatment and control groups and the event-related potential technique was used to test the effects of a blended essential oil on improving human cognitive ability.The results showed that the blended essential oil significantly improved human’s attention and eliminated the differences in the P300 amplitude in the postcentral area of the brain between the negative priming condition and the control condition.However,there was no significant difference between working memory and computational task.The present study thus suggests that blended essential oil can modulate the P300 amplitude in the postcentral area,which may improve human attention.
