汉语阅读困难儿童脑电功率分析

EEG SPECTRA STUDY ON CHINESE DYSLEXIA UNDER EYE-CLOSED STATE

目的：探讨阅读困难儿童脑电图的特征性标志。方法：对阅读困难儿童在安静状态下的脑电绝对功率进行分析。结果：在某些脑区，阅读困难儿童的脑波各频段均较对照组减少。结论：阅读困难儿童可能存在脑觉醒程度过高，各脑区脑电发育与同龄儿童有差异。

ONective:To further investigate the features of EEGs of Dyslexics.Methods Spectral anal-ysis was applied to 10 channels EEGs of 17 dyslexic children and 17 normal children under eye-closed resting state. Results:Absolute power in all broad bands in some regions was significantly smaller in dyslexic children than that in normals,Conclusion:Dyslexics with over arousal levels may have a differ-ent developmental EEG pattern.
