【摘要】 本文分析描述了60例4～12岁正常儿童闭眼、睁眼及深呼吸后一分钟的δ、θ、α和β四种频段脑电地形图的统计特点。得出正常儿童脑电分布和变化随年龄和状态变化的基本情况,并对部份特点进行了讨论。认为闭眼状态BEAM所显示的规律性明显,个体差异小,对称性较好,因此,临床判读应以闭眼时为主。更多还原

【Abstract】 This paper described the statistical characteristics of 60 normal children(4～12 years) in brain electric activity mapping (BEAM) in four frequency bands at the state of closing eyes, opening eyes, andoat one minute after deep breathing. The basic situation of BEAM distribution and changing were obtainded from norm children on varies states and ages. The results showed that the regularities of BEAM on closing eyes state were obvioas, the individual differences were little and the symmetry were good. Therefore, we considered that it is better for us to make a clinically judje mainly from closing eye state.更多还原
