Step 1 Introduction on Short term facilitation:

Neural facilitation, also known as STF (Short term facilitation) is a phenomenon in neuroscience in which postsynaptic potentials (PSPs) evoked by an impulse are increased when that impulse closely follows a prior impulse. STF is thus a form of short-term synaptic plasticity. The mechanisms underlying neural facilitation are exclusively pre-synaptic; broadly speaking, PPF arises due to increased presynaptic Ca²⁺concentration leading to a greater release of neurotransmitter-containing synaptic vesicles. Neural facilitation may be involved in several neuronal tasks, including simple learning, information processing, and sound-source localization.
