Long-term depression at hippocampal mossy fiber-CA3 synapses …
Apr 20, 2021 · Our results show that neither acute nor chronic inhibition of p75NTR signaling impairs MF-LTD, while short-term plasticity, in particular paired-pulse facilitation, at MF-CA3 …
学术前沿！南方医科大学高天明课题组首次发现调节突触可塑性和 …
Oct 20, 2021 · 海马脑区的 长时程增强（ long-term potentiation ，LTP）是研究最多的一类突触可塑性，同时也被认为是学习记忆的一种细胞机制【1 】。 LTP根据其维持时间的长短可分为早 …
程仅与突触后受体有关[7]．MFCA3突触的LTP为 非NMDA受体依赖型，脑片研究表明，该突触通路 的强直性LTP在其诱导和维持过程中双脉冲易化 （Pairedpulsefacilitation，PPF）效应会下 …
Presynaptic Ca2+ Entry Is Unchanged during Hippocampal Mossy …
Dec 15, 2002 · The hippocampal mossy fiber (MF)–CA3 synapse exhibits NMDA receptor-independent long-term potentiation (LTP), which is expressed by presynaptic mechanisms …
Multiple forms of LTP in hippocampal CA3 neurons use a …
We investigated long-term potentiation (LTP) at mossy fiber synapses on CA3 pyramidal neurons in the hippocampus. Using Ca 2+ imaging techniques, we show here that when postsynaptic …
Spike Train Timing-Dependent Associative Modification of …
Feb 5, 2004 · We here report that long-term potentiation (LTP) at the A/C synapses can be induced by association of brief spike trains in mossy fibers (MFs) from the dentate gyrus and …
Quantal mechanism of long-term potentiation in hippocampal …
Jun 1, 1994 · The quantal mechanism underlying the expression of long-term potentiation (LTP) was studied in the mossy-fiber (mf) synapses of the rat hippocampus. Whole-cell recordings …
Joint CP-AMPA and group I mGlu receptor activation is required …
Sep 9, 2014 · Repetitive activation of dentate gyrus PIIs by excitatory mossy fiber (MF) inputs induces Hebbian long-term potentiation (LTP). In contrast, long-term depression (LTD) …
Protein synthesis inhibition blocks the induction of mossy fiber …
Nov 15, 2000 · Protein synthesis inhibitors block mossy fiber(MF) LTP maintenance in vitro, but little is known about the effect of protein synthesis inhibitors on either induction or …
海马MF-CA3突触习得性LTP诱导后PPF效应的变化 - scnu.edu.cn
Abstract: The technique of paired-pulse test combined with electrophysiology and behavioral learning was used to examine the effect of behavioral long-term potentiation (LTP) on paired …
