Readily releasable pool
Webstrong enough to exhaust the readily releasable pool before the application of the agent (Gillis et al., 1996). Retinal bipolar cells are the second-order neurons, receiving inputs from rods and/or cones and feeding outputs to ganglion and/or amacrine cells. PKC is ubiquitously found in rod bipolar cells of various species (Negishi et al., 1988). WebJan 5, 2016 · Here, we investigate the ultrastructural and functional effects of Arf6 silencing in hippocampal synapses and reveal an unexpected presynaptic role for this small GTPase in determining the size of the readily releasable pool of SVs and in promoting direct versus endosomal recycling of SVs.

WebJun 1, 1996 · A pool of readily releasable quanta has been defined for hippocampal synapses ( Stevens and Tsujimoto 1995) and retinal amacrine cell synapses ( Borges et al. 1995) in culture. This pool consists of about 12 quanta per synapse, and when the pool has been completely depleted, replenishing it takes about 10 s in hippocampal synapses. WebSome studies also outline the importance of having a readily releasable pool (N RRP) with more than one vesicle for synaptic plasticity (Nadkarni et al., 2010). Despite the importance of MVR in information transmission and processing between neurons, we lack an understanding of its role in brain regions such as the neocortex, which is the seat ...
WebOct 24, 2024 · Interestingly, the fraction of the readily releasable pool forming the IRP seems to be more relevant as the concentrations of Ca \(^{2+}\) buffer increases, as can be seen for the cases of 5 and 5.5 mM, where it can be appreciated that having vesicles at the IRP (RRP with a 10% of IRP) allowed the active zone to produce a considerably higher ... WebNov 8, 2024 · Consistent with differential preNMDAR signaling in evoked versus spontaneous release, preNMDAR regulation of evoked neurotransmission maintained release probability during high-frequency firing by increasing the replenishment rate of the readily releasable pool, instead of directly affecting release probability, as might be …
