Potential mechanisms of synaptic plasticity mediated by changes in release-receptor alignment. These changes may arise from repositioning or change in the number or position of release sites presynaptically, from altering the number, position, size, or internal density of postsynaptic receptor clusters, or from changing the nature of transsynaptic coupling. Panels with notations depict mechanisms that have support from direct or indirect evidence in the literature.
