摘要
本文运用谱分析及计算机判别分析法对陕西省柞水县20名不明原因智能低下患儿脑电信号进行分析,实验结果显示δ波及θ波百分含有率增加,α波百分含有率下降,各波总能量比对照组低。以上脑电改变,提示该类患儿有特殊病理损害。脑电信号功率谱阵图计算机分析显示了一定的优越性,有望为诊断此类患儿提供客观指标。
In this paper EEGs spectral analysis and computer recognition method have been applied to 20 children from the Zashue County of Shaanxi Provence, who are suffering from mental retardation of endemic etiology unknown. The results of the experiment show that the energy ratio of DELTA and THETA bands increases and that of ALPHA band dicreases. The total energy of all bands becomes smaller than the contro group. The patterns of EEG suggest that some particular pathological damage should occur in these children. The obvious advantages of using computer analysis may be the indexes to diagnosis this kind of disease.
