额区脑波年老化特点及其与某些认知能力的相关性

对１２０名中老年被试（４６－８０岁），完成双额脑波年老化特点０及其与某些认知能力相关性的研究。认知能力测验共１２项作业，包括４项作业速度和１０项作业成绩共１４项指标。结果表明：（１）双额脑波α峰频率随年老低移，α功率随年老有增加趋势；（２）年老过程３项作业速度与双额α峰频率相关性显著，但仅“图象自由回忆”成绩与双额α峰频率及右额α功率相关性显著。

FRONTAL EEG CHARACTERS IN AGING AND ITS CORRELATIVITY WITH SOME COGNITIVE ABILITIES

A study on the frontal EEG characters in aging and its correlativity with some cognitive abilities was accomplished on 120 subjects of 46 to 80 years of age. The cognitive ability test consisted of 12 tasks and included 4 items of speed and 10 items of performance,total 14 indexes. The results indicated:1) The alpha peak frequencies slowed down and the alpha powers showed with age a tendency of increase in the left and right frontal areas: 2) The speeds of three tasks correlated significantly with the alpha peak frequencies in both the frontal areas, but only the performance of "free recall of picture"correlated with the alpha peak frequency in both the frontal areas and the alpha power in the right area in aging.
