Action potentials are multi-functional signals in plants. While most plant cells are conductive, and electrically coupled with each other, the action potentials are channelled faster along the plants' vascular network. Conductivity of the networks is geometrically constrained, thus allow for selective propagation and interaction between the impulses. Using FitzHugh-Nagumo model we show that it is possible to realise a functionally complete set of Boolean functions by selecting locations of stimulating and recording electrodes. The results pave theoretical grounds for further experimental studies of plant-based computing.
动作电位是植物中的多功能信号。虽然大多数植物细胞具有导电性，并且相互电耦合，但动作电位沿着植物的维管网络传导得更快。网络的导电性受到几何限制，因此允许脉冲之间进行选择性传播和相互作用。我们使用菲茨休 - 纳古莫模型表明，通过选择刺激电极和记录电极的位置，可以实现一组功能完整的布尔函数。这些结果为基于植物的计算的进一步实验研究奠定了理论基础。
