摘  要:目的通过比较边缘智力(borderline intellectual functioning,BIF)儿童和健康对照组(typically developing control,TDC)的脑电频谱(EEG power spectra)绝对功率值的特征,探讨BIF儿童的神经认知功能与神经电生理信号变化的关系及影响因素。方法采用128导高密度脑电记录系统采集静息闭眼脑电并基于小波变换(wavelet transform)方法获得频谱特征,采用Conners父母症状问卷、中国韦氏儿童智力量表评估,比较了30例BIF儿童和42例TDC儿童频谱特征、行为问题和智力水平的差异。结果(1)BIF儿童[品行问题(0.78±0.16)分,学习问题(1.53±0.14)分,心身障碍(0.17±0.04)分,冲动-多动(1.13±0.14)分,焦虑(0.52±0.08)分,多动指数(1.04±0.10)分]的PSQ各行为因子得分均高于TDC儿童[品行问题(0.21±0.03)分,学习问题(0.35±0.05)分,心身障碍(0.07±0.02)分,冲动一多动(0.27±0.05)分,焦虑(0.26±0.03)分,多动指数(0.25±0.04)分],差异有统计学意义(P〈0.05)。(2)α波段特征:两组儿童在大脑左右半球(F=14.44,P〈0.01)和前后半球(F=29.54,P〈0.01)出现主效应;左右半球与前后半球间出现交互效应(F=8.55,P〈0.01),仪波在右侧后半球活动最显著。(3)β波段特征:两组儿童在大脑左右半球(F=6.49,P=0.01)和前后半球(F=8.01,P=0.01)出现主效应;两组儿童在左右半球与类型之间交互效应显著(F=5.84,P=0.02),左右半球与前后半球之间交互效应显著(F=10.51,P〈0.01),右侧前部和右侧后部活动更为显著。(4)δ波段特征:两组儿童在前后半球(F=11.15,P〈0.01)出现主效应,前半球活动大于后半球。(5)θ/β比值(TBR)特征:两组儿童在前后半球出现主效应(F=8.81,P〈0.01);两组儿童在左�Objective To investigate the features of absolute electroencephalogram (EEG) power spectra in children with borderline intellectual functioning (BIF) as well as their correlation with cognitive function and behavioral problems. Methods 30 children with borderline intellectual functioning and 42 typical developing children (TDC) were recruited in this study. All of them underwent the Chinese Revised Wechsler Intelligence Scale for Children (C-WISC) and their behavioral problems were assessed according to the Conners' Parent Symptom Questionnaire (PSQ). Resting EEG of 128 electrodes were recorded when the participants closed their eyes and analyzed using wavelet transform to assess the absolute power of alpha, beta,theta,gamma and theta/beta ratio (TBR). Results ( 1 ) PSQ scores of BIF ( conduct problems(0.78± 0.16) , learning problems ( 1.53 ± 0.14) , psychosomatic disorder ( 0.17 ± 0.04) , impulsivity-hyperactivit ( 1.13 ± 0.14 ) , anxious( 0.52±0.08 ), hyperactivity inde(1.04±0.10) ) were higher than TDC ( conduct problems( 0.21 ±0.03 ), learning problems( 0.35±0.05 ), psychosomatic disorder( 0.07±0.02), impulsivity-hyperactivit ( 0.27±0.05) ,anxious(0.26±0.03) ,hyperactivity index(0.25±0.04) ), and the difference was statistically significant(P〈0.05). (2)alpha band :the main effects of the two groups on the left and right hemisphere (F= 14.44, P〈0.01 ) and the anterior and posterior hemispheres (F= 29.54, P〈 0.01 ) were significant. The interaction effect between the left and right hemisphere and the anterior and posteriorm hemispheres was significant(F= 8.55 ,P〈0.01 ).The activity of the alpha wave was signifieant in the right posterior hemisphere. (3)The main effects of the two groups on the left and right hemispheres (F= 6.49,P= 0.01 )and the anterior and posterior hemispheres(F=8.01 ,P=0.01 ) were significant.The two groups had significant interaction effects between t
