A Keller-Segel model for C elegans L1 aggregation
Fig 2
Simulation of the attractant-only model.
This figure shows the state of a numerical simulation of the attractant-only model after 20 0000 s (2 days and 7 hours). The initial condition was a uniform worm density of 
, perturbed by normally distributed random noise of standard deviation 1% (i.e. 90 cm−d). (The entire time courses can be seen in S2 and S3 Videos in the Supporting Information.) S1 Fig shows results at t = 200 000 s and t = 1 × 107 s (116 days) of ten independent runs of the same simulation with different pseudorandom noise in the initial condition. Panels A, B show the results of simulations in one-dimensional space; C, D show results in two-dimensional space. A, C show density ρ; B, D show attractant concentration U. The two numbers below each plot are the minimum and maximum values of the plotted function over the entire 1 cm × 1 cm domain. The spatial units are centimeters.
