查询词典 postsynaptic

BACKGROUND: F-wave is a late muscle response which results from the antidromic activation of spinal motorneurones following peripheral nerve supramaximal electrical stimulation,and influenced by the balance of excitatory and inhibitory postsynaptic potentials on spinal motomeurons.

背景：F波是末梢神经接受最大电刺激，从肌肉诱发出来的后期合成活动电位之一，是脊髓运动神经元突触后电位的反映，对F波的研究已经被作为衡量脊髓运动神经元兴奋性的一种手段。

Methods: The conventional intracellular recordings were conducted in MNs of spinal cord slices isolated from neonatal rats (8~14 days old). Observed in MNs were the effects of TRH on excitatory postsynaptic potentials evoked by contralateral ventrolateral funiculus stimulation i.e.

应用新生大鼠（8~14d龄）脊髓切片MN细胞内记录技术，TRH灌流给药，观察其对cVLF电刺激诱发的兴奋性突触后电位的影响。

Results: Among 32 tested MNs, depolarizing responses(excitatory postsynaptic potential, EPSP) were elicited by cVLF stimulation in 21 MNs, hyperpolarizing response (inhibitory postsynaptic potential, IPSP) in 1 MN, and IPSP preceded by EPSP in 4 MNs. The cVLFEPSPs were stimulus intensity-dependent, and could be abolished by low Ca(superscript 2+)/high Mg(superscript 2+) solution. compared with iVLF-EPSPs, cVLF-EPSPs showed longer latency (P.001). The cVLF-IPSP presented with membrane potential-dependent property and was eliminated by the perfusion of picrotoxin (30 μmol/L) and strychnine (1.0 μmol/L).

结果：在32个测试的MNs，观察到cVLF电刺激可在21个MNs上诱发去极化反应（即cVLF性兴奋性突触后电位，cVLF-EPSP），在1个MN上诱发超极化反应（即cVLF性抑制性突触后电位，cVLF-IPSP），在4个MNs上诱发cVLF-EPSP后复合有cVLF-IPSP的反应。cVLF-EPSP具有刺激强度依赖性、被低钙高镁溶液取消的特性，与i VLF性EPSP相比，有潜伏期较长的特点(P.001)。cVLF-IPSP呈膜电位依赖性，并被印防己毒素(30μmol/L)及士的宁(1.0μmol/L)取消。

Propofol induced Cl- currents at concentrations of 10-5 and10-4 M, which were sensitive to picrotoxin and, to a lesserextent, to strychnine. Propofol (10-6 M) enhanced -aminobutyricacidA (GABAA; 10-6 M)-induced current synergistically. Moreover,propofol (10-5 and 10-4 M) significantly increased the decaytime of evoked-inhibitory postsynaptic currents, which suggestsa postsynaptic modulation of GABAA receptors.

异丙酚在浓度10-5~10-4M 时，産生 Cl-电流，对印防己毒素敏感，在更小浓度范围内，对番木鼈碱敏感。10-6M 的异丙酚加强 GABAA 産生的电流，另外，异丙酚（10-5、10-4M ）显著地增加了突触后诱发-抑制电流的衰退时间，提示了 GABAA 受体的突触后调节作用。

Cellular structure is simple and has intermediate neurons, which can survive a longer period in vitro. Amphibial sympathetic ganglions show various postsynaptic potential including fast excitatory postsynaptic potential. Slow inhibitory postsynaptic potential.Slow exeitatory postsyn...

两栖动物交感神经节表现出多种突触后电位，包括快兴奋性突触后电位，慢抑制性突触后电位，慢兴奋性突触后电位，晚期慢兴奋性突触后电位，同时还表现多种突触塑性，说明该神经节具有信息存储功能，因此，两栖动物交感神经节可作为研究学习与记忆的模型系统。
