STEPS - Geometry preparation toolkit
On the left you can see dendrites with different numbers of spines and visually watch how the molecules inside spread out, or diffuse, differently when there are more spines.
On the right, you can numerically see the distribution of molecules in the spines versus the shaft showing the molecules getting caught in the spines, which is called anomalous diffusion.
