Short-term synaptic plasticity results from use-dependent activity, lasts on the timescale of milliseconds to minutes, and is thought to underlie working memory and neuronal information processing. Here, we focus on two forms of short-term plasticity: 1) post-tetanic potentiation (PTP), which is induced by high-frequency stimulation, and 2) presynaptic ionotropic receptoractivated synaptic enha...
