本文报道了215名正常人体的脑电活动的积分频谱分析。提供了有关正常值可供个体诊断和群体普查时参考。正常人体的脑电分频积分振幅以a波为最高,尤其是40岁以下的人,慢波(б+θ)和快波(β_1+β_2)的积分振幅随着年令的增长而增大,a波则相对减少。分频积分指数与性别无一定关系,而与年龄有关。经相关分析,慢波与年龄呈正相关,相关系数为γ=0.287,P<0.01,而a波则呈负相关,γ=0.538,P<0.01;上述慢
This paper reports the integral spectrum analysis of 215 normal human beings. Provides a reference to normal values for individual diagnosis and population census. The amplitudes of EEG integrals in normal subjects are highest in a wave, especially those under 40 years. The integral amplitudes of slow wave (б + θ) and fast wave (β_1 + β_2) increase with the increase of year , a wave is relatively reduced. There is no relationship between frequency score and sex, but with age. Correlation analysis showed that the slow wave was positively correlated with age, the correlation coefficient was γ = 0.287, P <0.01, while a wave was negatively correlated, γ = 0.538, P <0.01;
