Forces at the synapse exhibit two components. a Time-lapse images of individual beads showing displacement tracks in coordinated and non-coordinated type of movements, scale bar is 0.3 µm. b Scheme showing the method used to separate the bead population in two pools, allowing extraction of coordinated and non-coordinated displacements. c Mean bead distribution in coordinated and non-coordinated pool of stress (n = 100 cells). Below: radial profile of the density map obtained by average spatial distribution of the beads by resizing all cells and interpolating each bead with a Gaussian kernel. d Mean displacement field map obtained by resizing and averaging (over all cells) at the indicated time point the individuals coordinated and non-coordinated stress maps
