2021年6月21日 · 在目前的研究发现中,发现ltp重要核心机制主要发生在突触后,同时突触前、神经元自身、神经营养因子(bdnf)也发现可以增强突触效能的机制。接下来,要介绍的是目前研究得最清楚的,在海马体中的ca3->ca1突触的ltp机制。 1.1、ampa受体 和 nmda受体
Stepwise synaptic plasticity events drive the early phase of …
2021年11月12日 · Using optogenetics to selectively erase long-term potentiation (LTP) within a defined temporal window, we found that distinct phases of synaptic plasticity play differential roles. The first wave acts locally in the hippocampus to confer context specificity.
不同的ltp诱发方式有什么区别吗? - 知乎
一般来说,100hz和200hz单串电刺激只会产生早期阶段(early LTP),持续1~3小时,该阶段内后膜上没有观察到新插入的AMPA受体,但是前膜受刺激后突触囊泡成功释放的概率大大增加(是的,并不是一有刺激囊泡就会成功释放的)。这一点可以从FM染料(Fei Mao dye ...
Serotonin dependent masking of hippocampal sharp wave …
2016年2月1日 · In acute slices from dorsal hippocampus, SPW-Rs can be induced by repeated high frequency stimulation that induces long-lasting LTP. We used this model to study SPW-R appearance and modulation by 5-HT. Although stimulation in presence of 5-HT permitted LTP induction, SPW-Rs were “masked” – but appeared after 5-HT wash-out.

同样是电刺激,为什么高频会诱导LTP而低频诱导LTD? - 知乎
现在已经比较确定的NMDA-receptor dependent的LTP和LTD的诱导机理表明,不同频率的刺激诱发的突触后钙离子信号增强会差异化地激活CaMKII / calmodulin或者calcineurin通路,其中CamKII/ calmodulin会使突触后的AMPA受体磷酸化从而转运到突触后膜上,增加AMPA的数量,另一方面 ...
