Cellular Intelligence by Nonlinear Dynamics in a Slime Mold.

单细胞生物体中的高级信息处理机制在一个大的变形细胞的绒泡菌原生质体的非线性动力学方面澄清。迷宫解决：生物体在迷宫中以这样一种方式发展静脉，即最初位于迷宫中死端的静脉消失，连接入口和出口的静脉变厚。当有两条路径时，选择较短的一条。因此，有机体连接从入口到出口的最短路线。2.脉体形成与韵律收缩的耦合：脉体沿着韵律收缩的相位梯度形成，韵律收缩是通过外界温度的振荡人为产生的.大小控制：通过暴露于低温或用光照射，大型变形虫细胞分裂成许多碎片。通过红外和远红的作用光谱和拮抗作用，说明光敏色素是光感受器之一.时间记忆：低温处理的效果以这样一种方式保持，即暴露的总时间保持恒定。

The mechanism of higher information processing in a single cellular organism is clarified in terms of nonlinear dynamics in a large amoeboid cell of the Physarum plasmodium.1. Maze-solving : The organism develops veins in a maze in such a way that veins which located initially at dead ends in a maze disappear and those which connect entrance and exit become thick. When there are two pathways, shorter one is selected. Thus, the organism connects the shortest route from entrance to exit.2. Coupling among vein formation and rhythmic contraction : The veins are formed along the phase gradient of the rhythmic contraction which are artificially generated by oscillating the external temperature.3. Size control : The large amoeboid cell fragments into many pieces by exposure to low temperature or by irradiation with light. Action spectroscopy and antagonistic action of red and far red indicate that one of the photoreceptors is phytochrome.4. Time Memory : The effects of low temperature treatment remain in such a way that the total time of exposure is kept constant.
