WebJan 31, 2024 · We find that the readily releasable pool, which comprises vesicles that are docked or tethered to release sites, is fed by a small-sized pool containing approximately one to four vesicles per release site at rest. This upstream pool is significantly depleted even after a short stimulation train. WebIn this study we present a novel method to estimate the number of release sites per synapse, also known as the size of the readily releasable pool (N RRP ), from paired whole-cell recordings of connections between layer 5 thick tufted pyramidal cell (L5_TTPC) in the juvenile rat somatosensory cortex. dyson v8 animal red light
