突触

At first, a model of a pair of excitable neurons coupled via gap junction is built by Chay model, the effect of the strength of gap junction on the synchronous oscillation is studied;then, the synchronous oscillations of a 2-D network are also studied;at last, the Lyapunov exponent and phase portrait are utilized in the analysis of nonlinear, the approximate entropy is utilized to measure the complexity.

首先以Chay模型为基础建立了两个神经元电突触耦合模型，研究了不同电突触耦合强度对两个神经元同步振荡的影响；其次，研究了可兴奋神经元组成的二维网络的同步振荡；最后，应用李雅普诺夫指数和相图分析了同步振荡的非线性，应用近似熵分析了同步振荡的复杂性。

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。

Here, temporal synaptic stability and the functional consequences for presynaptic operation will be considered.
