Analysis for the computation, memory and learning abilities of the Physarum plasmodium in terms of intelligent informatics

多头绒泡菌（Physarumpolycephalum）的原质团是一种单细胞、多核的巨型变形虫。最近的研究表明，生物体中存在计算、记忆和学习能力。在这项研究中，我们试图阐明这种现象的机制，并进行了一些实验。结果表明：1.原质团的运动受某些异速生长定律支配。2.原质团具有趋磁性。3.疟原虫具有联想学习的能力。此外，我们还根据实验结果进行了一些模拟，找到了一些理解这些现象的线索。

The plasmodium of true slime mold Physarum polycephalum is a unicellular and multinuclear giant amoeba. Recent studies demonstrated the presence of the abilities of computation, memory and learning in the organism. In this study, we tried to elucidate the mechanism of such phenomena and performed some experiments. As a result, we got following findings: 1. The motility of the plasmodium is ruled by some allometric laws. 2. The plasmodium has magnetotaxis. 3. The plasmodium is capable of associative learning. Furthermore, we found some clues to understand these phenomena by performing some simulations based on our experimental findings.
