Splet25. sep. 2024 · Long-term plasticity alters short-term plasticity dynamics. The induction of long-term plasticity is known to alter short-term plasticity when long-term changes are expressed presynaptically [37, 43]. LTD induction, for example, reduces short-term depression due to a reduction in transmitter release.
