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.

真菌菌落通过沿菌丝体网络的细胞质流来维持其完整性。这种流动以及菌丝体尖端传播的可能协调，由钙波和相关的电位变化波控制。我们建议可以将这些激发波用于在菌丝体网络中执行计算。我们使用FitzHugh–Nagumo模型来模拟激发在黑曲霉单个菌落中的传播。布尔值由细胞外电位的尖峰编码。我们用一对选定电极上的电脉冲表示二进制输入，并记录来自16个电极的菌落响应。我们导出了可实现真菌菌落的两输入输出逻辑门集，并分析了门的分布。
