Unbiased Random Walk

An agent-based model where each cell’s position and velocity is tracked Introduction We expand our exploration of local and non-local models to the class of agent-based models. Description Instead of tracking continuous distributions of cell density, neural activity, or other properties that vary continuously across space, we adopt a different kind of modeling approach by tracking the trajectories and behavior of individual cells.

Unbiased and biased random walkers Introduction We can simulate the swimming motion of a cell, such as a bacterium, by interspersing short periods of directed motion with random turns or random scrambling of the cell’s velocity.
