Actin and tubulin are key structural elements of Eukaryotes’ cytoskeleton. The networks of actin filaments and tubulin microtubules are substrates for cells’ motility and mechanics, intra-cellular transport and cell-level learning. Ideas of information processing taking place on a cytoskeleton network, especially in neurons, have been proposed by Stuart. Hameroff and Steen. Rasmussen in the late 1980s in their designs of tubulin microtubules automata and a general framework of cytoskeleton automata as sub-cellular information processing networks. The cytoskeleton protein networks propagate signals in the form of ionic solitons, travelling conformation transformations and breathers generated through electrical and mechanical vibrations. A collision-based, or dynamical, computation employs mobile compact finite patterns, mobile self-localised excitations or simply localisations, in an active non-linear medium. These localisations travel in space and perform computation when they collide with each other. Memristor is a device whose resistance changes depending on the polarity and magnitude of a voltage applied to the device’s terminals and the duration of the voltage’s application.
