论文摘要
真菌菌落通过沿菌丝网网络的细胞质流动保持其完整性。这种流程,以及菌丝尖端传播的可能协调,由钙波和相关的电势变化波控制。我们建议可以使用这些激发波来在菌丝网网络中实施计算。我们使用Fitzhugh-Nagumo模型来模仿尼日尔曲霉的单个菌落中激发的传播。布尔值由细胞外电位的尖峰编码。我们代表一对选定电极上的电脉冲输入二进制输入,并记录了16个电极的菌落反应。我们得出了可实现真菌菌落的两输入逻辑门的组合集,并分析了门的分布。
A fungal colony maintains its integrity via flow of cytoplasm along mycelium network. This flow, together with possible coordination of mycelium tips propagation, is controlled by calcium waves and associated waves of electrical potential changes. We propose that these excitation waves can be employed to implement a computation in the mycelium networks. We use FitzHugh-Nagumo model to imitate propagation of excitation in a single colony of Aspergillus niger. Boolean values are encoded by spikes of extracellular potential. We represent binary inputs by electrical impulses on a pair of selected electrodes and we record responses of the colony from sixteen electrodes. We derive sets of two-inputs-on-output logical gates implementable the fungal colony and analyse distributions of the gates.
