摘　　要：目的:本文在综合各种已知的客观现象的基础上,对大脑处理复杂信息时候的逻辑原理进行建模。方法:以客观事实为依据,本文提出的基础观点是:由血液循环决定的,大脑中生化环境的周期性变化,是几十亿个脑细胞能够在处理复杂信息的时候协同运作的“基础时钟”。几十亿个脑细胞随着血液循环的“节拍”,呈现出一定的同步运作的规律——脑电波。从而解释了脑电波的产生原理,三种主要脑电波之间的关系。在这个观点的基础上,对大脑的运作的逻辑原理进行建模,对大脑如何感知物理世界的连续过程,在做梦和回忆的时候如何“想起”以前经历过的连续过程和日常中常见的各种心理体验提出解释。结果和结论:所建立的模型能够解释目前作者了解到的各种神经生物生学,解剖学,心理学,比较解剖学现象和实验结果。包括国内外最近的一些实验现象。Objective： This paper tries to construct a model to describe the principle of how brain processes complex information, on the basis of objective facts. Methods： A basic viewpoint of this paper is that the cyclical variation of biochemical environment in cerebra, which is determined by the blood circulation, is the basic timer for the cooperation of hundreds of millions of nerve cells in cerebra,which process complex information. The time of this timer is the origin of synchronous activity. In other words, it is the origin of kinds of waves on electroencephalogram （EEG）. This paper also explains the relationship between the three kinds of waves on EEG： αwave, βwave and δwave. A model of describing how cerebra process complex information, such as storing a continuous process of ＂pick an apple from the tree＂ or recalling this ＂film＂, is found on this concept of ＂blood cycle timer＂ and used to explain our daily mentality experiences. Conclusions： With this model, we can explain the phenomena of neural biology, anatomy, psychology, zootomy, and the results of recent experiments.
