突触

Compare with the curvation forms of synaptic interfac e of control animals and 3days after KA administration animals,the amount of smi le synapses is significantly decresed and the amount of frown synapses is signif icantly increased in the moleculous layer of d entate gyrus 7 days after KA injection.

In central nervous system only a limited number of vesicles exist in the presynaptic terminals.

中枢神经系统突触前的神经末梢只有少量的突触囊泡存在，突触囊泡数目的多少和融合模式将影响突触传递的效率。

The comparison was made of amplitudes of the postsynaptic potential evoked in AP cells by the stimulation of T, P and N cells. The results showed that for each type of T, P and N cell the contralateral member of the pair evoked larger synaptic potentials in the AP cell that did its ipsilateral homologue and the T, P and N cell with a dorsally situated receptive field produced a larger synaptic input on the AP cell that its counterpart with a ventrally situated receptive field.

分别比较T、P和N细胞在AP细胞上引起的突触后电位的幅度，可见对侧T、P和N细胞在AP细胞上引起的突触后电位幅度比同侧的T、P和N细胞在AP细胞上引起的突触后电位幅度大；具有背部感受野的T、P和N细胞在AP细胞上引起的突触后电位的幅度比具有腹部感受野的T、P和N细胞在AP细胞上引起的突触后电位的幅度大。

It showed that for each type of P and N cell the contralateral member of the pair evoked larger synaptic potentials in the AP cell that did its ipsilateral homologue and the P and N cell with a ventrally situated receptive field produced a larger synaptic input on the AP cell that its counterpart with a dorsally situated receptive field.

比较P和N细胞在AP细胞上的突触后电位幅度，可见对侧P和N细胞在邻节的AP细胞的突触后效应强于同侧的P和N细胞在AP细胞上的突触后效应；具有腹部感受野的P和N细胞在邻节AP细胞上的突触后效应强于具有背部感受野的P和N细胞在AP细胞上的效应。

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。

Gliosis is resulted in TLE. The synapse consists of the presynaptic and postsynaptic terminals, which in many synapses are surrounded by glial cell.

颞叶癫痫可导致神经系统胶质增生，突触后终端与胶质细胞之间形成突触，突触后终端的树突棘的形态学的变化引起突触结构的改变，与胶质细胞之间形成的突触为异位突触，引起海马内环路性质的变化，从而提高致痫性。

LTP is though to involve the release of one or more retrograde messengers from the postsynaptic cell that act on the presynaptic terminal to enhance glutamate release. One candidate retrograde messenger is the membrane permeant gas NO.

NO从突触后释放通过扩散作用于突触前膜，起逆向信使的作用，增加突触前谷氨酸的释放，使突触前突触后共同参与形成LTP。

Two kinds changes of neuron plasticity are confirmed being related to GAP-43:(1)synaptic structural change makes GAP-43 increase ;(2) changes of synaptic transduction efficacy that long term potential and long term depression can alter GAP-43 phosphatize state and mRNA expression.

突触素(synaptophysin，P38)系一相对分子质量为38000的膜结构蛋白，存在于突触前囊泡膜，与突触的结构和功能密切相关。P38作为突触前终末特异性标记物，常用来反映突触的密度和分布。

Two pathways may belong to the same functional system, though they have some architectural difference. It has been disscussed that some neural structures in the visceral afferent pathway may have some relation to the somesthetic afferent.

在梭形细胞的树突上见到较多的对称性突触，突触前末梢含有多形性囊泡；在卵圆形细胞的远核区和树突上，常见到含圆形囊泡的末梢，与胞体和树突形成不对称性突触。

The results suggest that there is prominent short-term synaptic depression in the rat thalamocortical visual pathway. Presynaptic transmitter depletion and postsynaptic GABAergic inhibition are the main possible mechanisms of this synaptic depression. The short-term synaptic depression is helpful in neuronal correlated firing detection.

以上结果表明：丘脑皮层视觉通路具有显著的短时程突触抑制特性，突触前的递质耗竭和突触后的GABA能抑制系统很可能是产生视通路短时程突触抑制作用的主要机制，突触抑制作用有助于视觉系统对同步发放活动的检测。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
