Xu-Friedman, Matthew A., and Wade G. Regehr. Structural Contributions to Short-Term Synaptic Plasticity. Physiol Rev 84: 69–85, 2004; 10.1152/physrev.00016.2003.—Synaptic ultrastructure is critical to many basic hypotheses about synaptic transmission. Various aspects of synaptic ultrastructure have also been implicated in the mechanisms of short-term plasticity. These forms of plasticity can greatly affect synaptic strength during ongoing activity. We review the evidence for how synaptic ultrastructure may contribute to facilitation, depletion, saturation, and desensitization.
