摘　　要：对 172名 6— 12岁的正常儿童进行脑波超慢功率涨落特点的研究。结果表明 :(1)各组优势涨落平均功率空间分布表现出额低枕高的前后梯度 ;(2 )随着年龄的增加 ,不同的脑区其发展趋势是不同的 ,且逆转现象逐渐减少 ;(3)左右脑表现出左小右大的不对称性 ;(4 )男女生脑波优势涨落功率的空间分布、逆转趋势、方位等有差异。上述结果说明 。In order to explore children's brain power distribution of ultra slow fluctuating graph and its developing traits, 228 subjects aged from 6 to 12 were analyzed through an ET encephalofluctuograph Technology System. The following were some of our results: 1) The superiority of staff power was increased with the age increasing while the most significant decline appeared in the brain domain of F3,C3, P3 O1 F7,T5, which showed a slow trend after 8 years; 2) There were changes with an up and down wave (at no regular interval) in that of F4,C4,P4,O2,F8 and T6 in the right brain; 3) The distributions of Pmax—Pmin in each age group were in regular order. Pmax had an absolute superiority in the occipital lobe, especially in O2. Pmin distributes in all the temporal lobe, especially in the fore temporal lobe. But Pmin seldom appeared in the domain of T6, and the gender difference was found significant(P<.01). For example, Pmin of the boys was mainly in the left temporal lobe while that of the girl mainly was in the right one; 4) The ratio of the right power compared with that of the left showed the male children generally had the superiority in the right brain and the female children in the left one.
