Abstract

Memristors close the loop for I-V characteristics of the traditional, passive, semi-conductor devices. A memristor is a physical realisation of the material implication and thus is a universal logical element. Memristors are getting particular interest in the field of bioelectronics. Electrical properties of living substrates are not binary and there is nearly a continuous transitions from being non-memristive to mem-fractive (exhibiting a combination of passive memory) to ideally memristive. In laboratory experiments we show that living oyster mushrooms Pleurotus ostreatus exhibit mem-fractive properties. We offer a piece-wise polynomial approximation of the I-V behaviour of the oyster mushrooms. We also report spiking activity, oscillations in conduced current of the oyster mushrooms.
