Brownian Motion on the Surface of a Spherical Cell as Given by Equation 1

<div><p>Figure 1 verifies that the SDE constructed in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.0020044#pcbi-0020044-e001" target="_blank">Equation 1</a> correctly describes the random diffusive movement of membrane bound particles. Shown are trajectories of a diffusing particle on the surface of a cell with 10 <i>μm</i> radius for a fixed time with different diffusion coefficients.</p><p>(A) <i>D</i> = 0<i>.</i>03 <i>μm</i>²/<i>s,</i> (B) <i>D</i> = 0<i>.</i>3 <i>μm</i>²/<i>s,</i> (C) <i>D</i> = 3 <i>μm</i>²/<i>s</i>.</p>
