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. WebMay 3, 2024 · Facilitation runs counter to the natural tendency of synapses to weaken during repeated activation, a phenomena known as depression that can result from depletion of the readily releasable pool (RRP) of synaptic vesicles and a decrease in neurotransmitter release ( Zucker and Regehr, 2002 ).
