Abstract This study evaluated the relationship between baroreceptor reflex sensitivity and cognitive performance. Twenty normal subjects performed the Uchida-Kraepelin test, a serial arithmetic task. Baroreceptor reflex sensitivity during a 5-min Uchida-Kraepelin test was assessed in minute periods by spectral analysis using the maximum-entropy method. During the task, baroreceptor reflex sensitivity was significantly reduced. There was an inverse between-subjects association between baroreceptor reflex sensitivity and the level of performance (number of additions completed) both at different time periods of the Uchida-Kraepelin test and during the whole task (r=-.51). This finding supports the existence of a pathway mediating mutual cardiovascular-central nervous system influences through the baroreceptors, establishing an essential mechanism facilitating adaptive reactions to stressful conditions.
摘要 本研究评估了压力感受器反射敏感性与认知表现之间的关系。20名正常受试者进行了内田-克莱佩林测验，这是一项连续算术任务。使用最大熵方法通过频谱分析在每分钟时间段内评估5分钟内田-克莱佩林测验期间的压力感受器反射敏感性。在任务期间，压力感受器反射敏感性显著降低。在不同时间段的内田-克莱佩林测验以及整个任务期间，压力感受器反射敏感性与表现水平（完成加法的数量）之间存在受试者间的负相关（r = -0.51）。这一发现支持了存在一条通过压力感受器介导心血管-中枢神经系统相互影响的途径，确立了促进对压力状况进行适应性反应的重要机制。
