摘要: 对120名20-79岁正常受试者完成了与年龄及认知功能相关的脑涨落图特点的研究。结果表明:(1)脑波优势涨落功率空间构型额低枕高梯度的随龄减小过程,在认知测验差组较好组明显;(2)脑波优势涨落功率受年龄与认知因素的交互影响集中于左前右后脑轴上;(3)脑波优势涨落功率前后梯度和左右不对称性变化表明,脑波活动的前后和左右调控可能在不同层次上发挥作用,并且,前后脑和左右脑的协调活动与认知功能有密切关系。上述结果说明,脑波功率涨落与认知功能及其老化过程有密切关系。

Abstract: A study on age-and cognitive function-related characteristics of encephalofluctuograph was accomplished in 120 normal subjects of 20 to 79 years of age. The results showed:(1)The age-related decreasing process of power gradient,in which there were low power in the frontal area and high power in the occiput area in the configuration of dominant power encephalofluctuograph,was more apparent in the group with poor performance of cognitive test than in the group with good performance of cognitive test,(2)The influence of the age×cognition interaction on dominant power in encephalofluctuograph was concentrated on the left-anterior/right-posterior brain axis.(3)The changes of anterior-posterior gradient and left-right asymmetry of dominant power in encephalofluctuograph indicated that the regulation and control of dominant power in anterior-posterior and left-right brain might bring into play in different levels,and the coordinative activities of anterior-posterior and leftright brain had close relations to cognitive function. The results suggested that power-encephalofluctuograph was closely relative to cognitive function and its aging process.
