Figure 2

Simulations of restricted diffusion. Plots illustrate the mean estimated motion-probability propagator perpendicular to the long axis of a cylinder with diameter 10 µm after 1 ms (A), 5 ms (B), and 25 ms (C) using three time-step durations. (The 5 ms time-step results are not shown in (A) because a 1 ms time-step cannot be accomplished with an integer number of 5 ms steps.) PDFs computed with different time-steps result in similar findings when at least five time-steps are performed. Note that simulated PDFs broaden with increased diffusion time. Error bars, which are smaller than the data points, indicate examples of the standard error at nine equally spaced distances.
