Slime mould memristors (2015)
Journal Article

In laboratory experiments we demonstrate that protoplasmic tubes of acellular slime mould \emph{Physarum polycephalum} show current versus voltage profiles consistent with memristive systems and that the effect is due to the living protoplasm of the... Read More about Slime mould memristors.

Transfer function of protoplasmic tubes of Physarum polycephalum (2015)
Journal Article

© 2015. The slime mould Physarum polycephalum is a large single celled myxomycete; its plasmodium consists of tubes which extend to find sources of food. It has been previously shown that the tubes are conductive with a resistance of approximately 3.... Read More about Transfer function of protoplasmic tubes of Physarum polycephalum.
