【摘要】 引用一种“信息传输”理论来研究不同生理状态时的脑电时间序列 .比较了正常人和在急性缺氧条件下、睡眠条件下及局灶性癫痫病患者的大脑皮层信息传输 ,发现在各种情况下的大脑皮层信息传输有非常特殊的现象 :在急性缺氧时 ,人的大脑皮层信息传输量各导联均较正常人高 ;当深睡时 ,各导联的信息传输量均较正常人低 ;局灶性癫痫病人痫性导联与其他导联间的皮层信息传输量有明显增加 ,而非痫性导联间的信息传输量则相对降低 .用脑皮层信息传输量来分析在不同生理状态下的脑电信号是一个极有潜力的方法 ,可能为研究和理解大脑的活动机理提供一条新的途径更多还原

【Abstract】 Information transmission of human brain cortex(ITC) is computed using the electroencephalogram time series such that comparison can be made for the ITC of acute hypoxia、deep sleep and normal subjects and partial epileptic patients. Observations show that all ITCs between every lead under acute hypoxia are higher than those of normal subjects. But all ITCs between every lead in deep sleep subjects are lower than that of normal. The ITCs are obviously higher between the epileptic lead(s) and the others for partial epileptic patients. On the contrary, they are relative lower between non-epileptic leads. The method has the potential to study the electroencephalogram time series in different physiological states,providing a new way to study the function of human brain.更多还原
