摘要: <正> 从国际脑电图研究情况来看,对于初生至3岁这个年龄阶段儿童的脑电現象研究比較丰富,3岁以上儿量的研究則相对貧乏。因此直到目前为止,对于分析成人以下的脑电图,因为缺乏“正常标准”而常常使正常与临床脑电图工作者感到困惑。Ellingson R.J.(1954)的研究指出,以成人为标准則大部分15岁以下少年与儿童的脑电图为异常。現有的正常儿童与少年的脑电活动知識大都来自Smith J.R.(1938)、Lindsley D.B.

Abstract: Investigations of the spontaneous and "evoked" potentials was carried out on 910 normal children and youths aged 8 to 20 years with an Ediswan 16-channel electroencephalograph. We have stimulated the majority of our subjects with "threshold" single and repetitive flashes of light:1. From 8—20 years the occipital rhythmic activity increases in frequency but decreases in amplitude with age. The range of changes in frequency always not exceeds 1±0.5/sec.2. From 8—20 years absence of θ waves has strict regularity. It disappears first from the occipital region, then from the temporal region and finally from the parietal region.3. There are positive correlation between the phenomenon of "dicrotic" and "multicrotic" and the development and maturation of the cerebral cortex of children and youths. Display of the phenomenon of "dicrotic" and "multicrotic" decreases with age.4. From 8—20 years the percentage of display of the "blocking" responses elicited by "threshold" single flashes increases with age. Beyond the age of 13, duration of the "blocking" responses usually exceeds 2 sec. and "full blocking" is always prominent.5. "Driving" responses elicited by "threshold" repetitive flashes show that neurons of the cerebral cortex of children and youths aged 8—16 years have the high plasticity.6. Our results show that it seems to have a period of acceleration of brain's development at about 13—14 years of age.
