In hippocampal neurons, ENH appears to be localized in presynaptic nerve terminals.

The act of presupposing; a supposition made prior to having knowledge presynaptic

Moreover, we found that presynaptic but not postsynaptic inactivation of presenilins alters short-term plasticity and synaptic facilitation.

并且我们还发现突触前而非突触后早衰蛋白失活将改变短时突触可塑性及易化。

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。

In addition, the number of synaptic sites that express detectable levels of GABARs was decreased by approximately 50% after activity blockade, although there was no reduction in the total number of presynaptic contacts.

另外，突触点的数量表示，在活动阻闭后GABARs可见的水准下降了约50%，虽然突触前接触的总数没有下降。

In the progress that presynaptic neuron was excited,which caused postsynaptic potential changing by the release of neurotransmitters,and then electrical signal was transferred,the function and form of synapses could change.

在突触前神经元兴奋，通过神经递质的释放，引起突触后电位的变化，从而完成电信号的传递过程中，突触本身的功能和形态都可能发生改变。

LTP manifests as a persistent increase in response of postsynaptic neurons to subsequent stimulation after tetanic stimulation of the presynaptic neurons.

本项目在我们以往研究的基础上，探讨与脊髓背角LTP表达和维持相关的几个重要问题。

To explore how gene products, required for the initiation of synaptic growth, move from the cell body of the sensory neuron to its presynaptic terminals, and from the cell body of the motor neuron to its postsynaptic dendritic spines, we have investigated the anterograde transport machinery in both the sensory and motor neurons of the gill-withdrawal reflex of Aplysia.

为了探索突触形成起始阶段所需的基因表达产物，由感知神经细胞体向脊柱终端，以及由驱动神经细胞体向联会后枝状脊柱的移动，研究人员对与海蜗牛腮回退反射有关的，感知和驱动神经的顺式传递装置。

The in vitro effects of Gln49-PLA_2 were examined using the chick biventer cervicis nerve muscle preparation. Gln49-PLA_2 caused a dosedependent blockade of neuromuscular transmission. The time required to cause 50% blockade was about 150 min at the highest concentration 100μg/ml. This inhibition appeared to be presynaptic in origin as evidenced by the lack of effect of toxin on responses to exogenous acetylcholine in the non-stimulated BCp.

Gln49-PLA_2能够剂量依赖性地抑制颈二腹肌神经信号正常传导并影响肌肉收缩，在100μg/ml剂量下，肌肉收缩幅度在150分钟后达到50%的抑制率；同时，随着Gln49-PLA_2浓度的降低，肌肉收缩幅度的抑制效率也逐渐降低；实验证明Gln49-PLA_2对突触后膜乙酰胆碱受体敏感性无影响，对神经肌肉信号传导收缩的抑制作用位点在突触前膜。

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。

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％。
