WebJun 1, 2006 · The pool of vesicles that is drawn from by the next action potential is commonly referred to as the readily-releasable pool (RRP) or the release-ready pool [20 •], and is replenished from the recycling or reserve pool (RP), also called the endo/exo (endocytosis and exocytosis) cycling pool (ECP) [21] or the releasable pool [20 •]. WebApr 1, 2024 · These vesicles constitute the readily releasable pool (RRP). The RRP size, and the probability of release of each vesicle within the RRP, together determine synaptic …
