abstract = {We introduce a computer-based simulation model for
coarse-grained, effective motor-mediated interaction between
microtubule pairs to study the time-scales that compose
cytoplasmic streaming. We characterise microtubule dynamics
in two-dimensional systems by chronologically arranging five
distinct processes of varying duration that make up
streaming, from microtubule pairs to collective dynamics.
The structures found were polarity sorted due to the
propulsion of antialigned microtubules. This also gave rise
to the formation of large polar-aligned domains, and
streaming at the domain boundaries. Correlation functions,
mean squared displacements, and velocity distributions
reveal a cascade of processes ultimately leading to
microtubule streaming and advection, spanning multiple
microtubule lengths. The characteristic times for the
processes span over three orders of magnitude from fast
single-microtubule processes to slow collective processes.
Our approach can be used to directly test the importance of
molecular components, such as motors and crosslinking
proteins between microtubules, on the collective dynamics at
cellular scale.},
