突触前的

The results of these cellular experiments are quantitatively similar to the results of behavioral experiments with the same protocol and parameters, suggesting that activity-dependent amplification of presynaptic facilitation may make a significant contribution to classical conditioning of the withdrawal reflex.

这些细胞实验与同样方法和参数下的行为学实验有著同样的定量结果表明突触前的活动依赖性增幅对撤回反射中的经典制约有重大贡献。

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

应当考虑突触前的手术对临时突触的稳定性和相应功能的影响。

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。

It was demonstrated that toosendanin was a selective presynaptic blocker, which blocked the neurotransmitter release both in peripheral and central nervous system.

已有的研究表明，它是一种作用于突触前的特异性传递阻断剂，通过抑制神经递质释放阻断神经肌肉接头和中枢神经系统的兴奋传递。

Alpha-Synuclein is a presynaptic nerve terminal protein of unknown function, although several studies suggest it is important for synaptic plasticity and maintenance.

A-synuclein是一未知功能的突触前的神经末端蛋白，即使许多研究提出它对于突触可塑性和维持非常重要。

Puzzlingly, such effect is transient and depression is usually reinstated after the first episode of recovery sleep, or even after short naps .

睡眠剥夺可能通过改变5-羟色胺(serotonin 5-HT)系统起作用，5-HT_(1A)受体作为突触前的自身受体在调节中缝核5-HT神经元的活性中发挥着关键作用，并且作为突触后受体介导5-HT对边缘系统、皮层、下丘脑及其它一些脑区部位的作用，使得5-HT_(1A)受体的调节对于精神疾病非常重要。

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。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
