摘要

本文分析50例正常人脑电功率谱及

发现正常人脑电百分比功率左右对称性好.其功率均值的阶差≤3级

自前额到枕区

慢波逐渐减少

快波α节律增多

各脑区以α节律为主

过度呼吸对脑电功率谱及BEAM影响不大.随年龄的增长

慢波功率增多

α功率变慢

但变化不明显

Abstract

BEAM of 50 normal persons were analysised. We found the percentage of power spectral of the left and right corresponding regions was symmetrical

and the difference in the mean value of pcv.er spectral between symmetrical areas is≤3 grades. The percentage of slow wave was decreased

the fast wave was increased from the frontal to occipital region. The background activity of brain was alpha rhythm. BEAM did not affect by hyperventilation. As the age increased

the percentage of slow wave was increased and alpha activity was decreased

but there is on significance
