Webb18 juni 2007 · It has been reported that the paired-pulse ratio (PPR), which is the ratio of the amplitude of the second response to that of the first, depends on the probability of … Webb10 maj 2024 · Additionally, we review how PNN removal affects plasticity-associated phenomena such as long-term potentiation (LTP), long-term depression (LTD), and paired-pulse ratio (PPR). The results are discussed in the context of the role of PV interneurons in circuit function and how PNN removal alters this function.

Webb12 okt. 2024 · Corticotrophin-releasing hormone (CRH) system has been shown to be involved in neuroplasticity changes evoked during drug withdrawal [25, 26]; however, how CRH neurons participate in the synaptic inhibition of the reward system following chronic opiate exposure remains undetermined. Webb14 nov. 2024 · The paired-pulse ratio (PPR; 50 ms interstimulus interval) varied widely among inhibitory connections between GABAergic neurons. The PPR of unitary IPSCs was enhanced by ω-conotoxin GVIA (CgTx; 3 μm), an N-type VDCC blocker, whereas blockade of P/Q-type VDCCs by ω-agatoxin IVA (AgTx, 200 nm) decreased the PPR.
WebbPeripheral synaptic targets are innervated by individual or a relatively low number of inputs, whereas neurons in the CNS receive numerous synaptic connections, which impedes attribution of spontaneous quantal events to any single synapse ( Megías et al., 2001; Gibbins and Morris, 2006 ).
