  Analysis of high-density superresolution imaging of receptors reveal the
organization of dendrites at the nano-scale resolution. We present here
simulations in empirical live cell images, which allows converting local
information extracted from short range trajectories into simulations of long
range trajectories. Based on these empirical simulations, we compute the
residence time of an AMPA receptor (AMPAR) in dendritic spines that accounts
for receptors local interactions and geometrical organization. We report here
that depending on the type of the spine, the residence time varies from one to
five minutes. Moreover, we show that there exists transient organized
structures, previously described as potential wells that can regulate the
trafficking of AMPARs to dendritic spines.
