A Keller-Segel model for C elegans L1 aggregation
Fig 3
Attractant+repellent simulation.
Panels A, D show density ρ, B, E show attractant concentration Ua, and C, F show repellent concentration Ur. The spatial units are centimeters. The two numbers below each plot are the minimum and maximum values of the plotted function over the entire 1 cm × 1 cm domain. Note the different scale of the attractant and repellent plots. The means are the same, but because repellent is a longer-range signal, it is smoothed much more by diffusion and varies less than attractant. (S4 and S5 Videos show the full time courses for these simulations. S2 Fig shows ten independent solutions of the two-dimensional system with different pseudorandom noise at time 0.)
