Readily releasable pool rrp
WebIn virtually every mature neuronal preparation, a class of “release-ready” vesicles has been defined and named the readily releasable pool (RRP). In hippocampal terminals, only a few vesicles are endowed with RRP status and these are readily discharged after only a couple of seconds at 10–40 Hz stimulation ( Stevens and Williams 2007 ). WebJul 31, 2024 · Yet it is debated whether anatomically-defined docked vesicles correspond to the population of vesicles that comprise the readily-releasable pool (RRP), a functional …

WebMay 15, 2024 · That is, the initial idea was that the RRP is a homogeneous pool (Elmqvist and Quastel, 1965; Vere-Jones, 1966), but there is now widespread agreement that some readily releasable vesicles are released more slowly than others during repetitive stimulation owing to a lower probability of release (Wu and Borst, 1999; Sakaba and Neher, 2001 ... WebIt is proposed that short term memory is prolonged firing of neurons which depletes the Readily Releasable Pool (RRP) of neurotransmitter vesicles at presynaptic terminals[12]. The pattern of depleted presynaptic terminals represents the long term memory trace and the depletion itself is the short term memory. After the firing has slowed down ...
WebApr 15, 2024 · The first phase, hereafter called ‘fast’, corresponds to the mobilization of granules belonging to the ‘readily releasable pool’ (RRP) by fusion to the plasma membrane and quasi-immediate excretion: it lasts for a few minutes. The second (‘slow’) phase lasts longer because it involves more complex phenomena such as trafficking to ... WebFeb 28, 2014 · To examine this possibility, we estimated the effective size of vesicle pool in the readily releasable pool (RRP) by measuring responses to repetitive stimulation at different frequencies. Fig. 3C and E show the time course of synaptic depression by stimulation at 1 and 20 Hz, respectively.
