根据意识的心理学、神经生理学研究和一些病例报告，从计算神经科学的角度，提出意识神经活动的特点，特别是意识活动的适度性特点，是文献中未见的．认为意识有相应的神经相关物作为活动的基础，给出意识活动的一种计算神经科学的假设，在这个假设的基础上，提出一个意识活动的理论测度，这种理论测度既可根据意识活动的能量消耗来取得，又可从神经生理学方法（４０Ｈｚ同步振荡）来估算．这种测度可很好地反映意识的流动性和文中提到的适度性特点，并对一些意识状态的特例进行推算，讨论了这种测度的意义．
According to the psychology of consciousness, neurophysiological studies and some case reports, from the perspective of computational neuroscience, it is proposed in the literature that the characteristics of conscious neuronal activity, especially the moderation of consciousness activities, are not found in the literature. On the basis of this hypothesis, we put forward a theoretical measure of consciousness activity. This theory measure can not only be based on the consciousness activity Of energy consumption to obtain, but also from the neurophysiological method (40Hz synchronous oscillation) to estimate. This measure can well reflect the mobility of consciousness and the characteristics of moderateness mentioned in the paper. It also deduces some special cases of the state of consciousness and discusses the significance of this measure.
