Are Slime Moulds Living Memristors?
In laboratory experiments we demonstrate that protoplasmic tubes of acellular slime mould Physarum polycephalum show current versus voltage profiles consistent with memristive systems. This result complements previous findings on memristive properties of other living systems (human skin and blood and leaves) and contributes to development of self-growing bioelectronic circuits.
متن کاملHabituation in non-neural organisms: evidence from slime moulds.
Learning, defined as a change in behaviour evoked by experience, has hitherto been investigated almost exclusively in multicellular neural organisms. Evidence for learning in non-neural multicellular organisms is scant, and only a few unequivocal reports of learning have been described in single-celled organisms. Here we demonstrate habituation, an unmistakable form of learning, in the non-neur...
متن کاملChemoattractant-mediated changes in cytoskeletal actin of cellular slime moulds.
We report changes in actin associated with the Triton-insoluble cytoskeleton following chemotactic stimulation in five species of cellular slime mould, Dictyostelium discoideum, D. mucoroides, D. purpureum, D. lacteum and Polysphondylium violaceum. Stimulation of amoebae with the chemoattractant specific for each species elicits a rapid increase in cytoskeletal actin content with a peak at 5 s,...
متن کاملCell mixtures of different species and strains of cellular slime moulds.
INTRODUCTION T H E cellular slime moulds have, in their life history, a period of feeding of separate independent amoebae which subsequently stream together (by a process involving chemotaxis) to central collection points. Each of the resulting cell-masses differentiates into a fruiting body; in most species there is a delicate tapering celluose stalk which surrounds the large vacuolate stalk-c...
متن کاملTwo-Gene Phylogeny of Bright-Spored Myxomycetes (Slime Moulds, Superorder Lucisporidia)
Myxomycetes, or plasmodial slime-moulds, are one of the largest groups in phylum Amoebozoa. Nonetheless, only ∼10% are in the database for the small subunit (SSU) ribosomal RNA gene, the most widely used gene for phylogenetics and barcoding. Most sequences belong to dark-spored Myxomycetes (order Fuscisporida); the 318 species of superorder Lucisporidia (bright-spored) are represented by only e...
