摘要
采用元胞自动机建立了脑海马神经元信息传递的计算机仿真模型，发现海马神经元从个体到群体，在时间尺度上均呈现出１／ｆ涨落。分析了模型的动力学特性，认为产生１／ｆ涨落的机制在于脑海马神经元处于自组织临界状态，即在混沌的边缘上进化。
Cellular automata is used to estabilish a computer sedated model of hippocampal neuron information transmission. Results show that from individual to group, 1/f fluctuation is presented on time scale. After analysing the dynamics of the model, we think the reason of 1/f spectrum is that the hippocampal neurons are stated in self-organized criticality, in other words, evolve on the border of chaos.
