We consider theoretical mechanisms of the influence of intracellular electric fields on directed polymerization and orientation of microtubules.
Numerical experiments show three possible scenarios of the system evolution similar to (1) cortical waves of polymerization of the oocyte skeleton after fertilization, (2) the process of ooplasmic segregation in the zygote of ascidia Clione, and (3) the process of ooplasmic differentiation in the oocyte of Drosophila.
A similar interaction between the membrane electric activity and directed polymerization of microtubules can also play a fundamental role in neuronal mechanisms of learning and memory.
