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.

关于真菌菌落中的布尔门

真菌菌落通过细胞质沿菌丝体网络流动来保持其完整性。这种流动，连同菌丝尖端传播的可能协调，是由钙波和相关的电势变化波控制的。我们建议这些激发波可用于在菌丝体网络中实现计算。我们使用 FitzHugh-Nagumo 模型来模拟单个黑曲霉菌落中的激发传播。布尔值由细胞外电位的尖峰编码。我们通过一对选定电极上的电脉冲表示二进制输入，并记录了来自 16 个电极的菌落响应。我们推导出一组可实现真菌菌落的两输入输出逻辑门，并分析门的分布。
