On Electrical Spiking of <i>Ganoderma resinaceum</i>

Abstract

Fungi exhibit action-potential like spiking activity. Up to date, most electrical activity of oyster fungi has been characterized in sufficient detail. It remains unclear if there are any patterns of electrical activity specific only for a certain set of species or if all fungi share the same “language” of electrical signalling. We use pairs of differential electrodes to record extracellular electrical activity of the antler-like sporocarps of the polypore fungus Ganoderma resinaceum. The patterns of the electrical activity are analyzed in terms of frequency of spiking and parameters of the spikes. The indicators of the propagation of electrical activity are also highlighted.
