认为P_3(或N_3)是三叉神经根及三叉神经脊束核的突触前和突触后的混合电位。 It was not the rnuscle potential. We believe that P3(N3 )is mixedpresynaptic and postsynaptic potentials evoked from the trigeminal root and nucleus of trigeminalspine bundle. | ||
一般来说,动作电位到达突触节会导致神经递质释放到突触间隙。 In general, action potentials that reach the synaptic knobs cause a neurotransmitter to be released into the synaptic cleft. | ||
第一,川楝素以先易化后抑制的双相作用干扰神经递质释放,阻遏神经肌肉接头和中枢神经突触的突触传递。 The first is that by interfering with neurotransmitter release by causing an initial facilitation, TSN eventually blocks synaptic transmission at both the neuromuscular junction and central synapses. | ||
TCP神经元的树突通常分别与轴突末端和突触前树突形成轴突突触和树突突触。 The dendrites of the TCP neurons usually make axodendritic synapses and dendrodendritic synapses with axonal terminals and presynaptic dendrites, respectively. | ||
与此同时,很少使用的突触开始枯萎。 At the same time, synapses that see little use begin to wither. | ||
这就是树突-这些小的突触。 There are the dendrites - these little tentacles here. | ||
在钳制电压为0毫伏条件下,记录自发的和背根刺激引起的抑制性突触后电流。 At the holding potential of 0 mV, spontaneous inhibitory postsynaptic currents (IPSCs) and dorsal root stimulation-evoked IPSCs were recorded as outward currents. | ||
这些结果表明,该突变不仅影响集聚蛋白诱导突触后结构的功能,也影响神经肌肉接头功能的维持。 These results indicate that the mutation does not interfere with the ability of agrin to induce postsynaptic structures but that it dramatically perturbs the maintenance of the neuromuscular junction. | ||
他认为其中的奥妙在于这种削弱是与每个突触原有的强度成比例的。 因此当人苏醒时每个突触的相对强度是不变的,但所有的突触强度比之睡前都减弱了。 others, but all synapses are weaker than they were when he went to sleep. | ||
不仅如此,突触的增加还需要更多的蛋白质、脂肪和更大的空间。 In addition, making them requires more protein and fats and they take up more space. | ||
