Furthermore, abnormal morphology, shrinkage and reduced density of dendritic spines and defects in LTP were observed in brains of the patients suffering from mental retardation and neurodegenerative diseases; many mutant genes found from these patients encode component proteins of signal transduction for neuronal plasticity. These studies on synaptic plasticity would certainly promote making the effective prevention and treatment procedures for mental and neurodegenerative diseases.

此外，在精神迟滞性疾病和神经退行性疾病患者脑内记录到异常的LTP，并发现神经元的树突棘数量减少，形态上产生畸变或萎缩，同时发现，产生突变的基因大多编码调节突触可塑性的信号通路蛋白，故突触可塑性研究也将促进精神和神经疾病的预防和治疗。

Three results are received:(1) The population of neurons can synchronize when the strength of gap junction is large enough and the process is chaotic and complex;(2) The nonlinear and complexity of the seriously disorder oscillation are larger than that of slightly disorder oscillation in a 2-D network;(3) The nonlinear and complexity of the oscillations with strong strength of gap junction are larger than that of that with weak strength of gap junction.

结果表明：电突触达到一定强度时神经元群才能同步振荡，这种活动是混沌和复杂的；同一网络中异常节律较严重的神经元活动的非线性和复杂性要强于异常节律较轻微的神经元；突触耦合强度较强时的神经元活动的非线性和复杂性要强于其在突触耦合强度较弱时的。

The neural synapse is usually directed to the chemical synapse, it is a special structure by which the

神经突触通常是指化学性突触，是神经元之间传导神经冲动的一种特殊结构。

The result indicates that the intracortical synaptic input was unchanged, but the thalamocortical synaptic input was depressed by sensory stimulation and this depression recovered with a time course that matched that of the recovery of sensory responsiveness.

结果表明，电刺激诱导出的皮层—皮层突触反应不受持续的触须刺激的影响，而电刺激诱导出的丘脑—皮层突触反应则由于持续的触须刺激而减小，而且突触反应的恢复时程与皮层细胞适应恢复的时程类似。

Methods: Based on the theory of "kidney produces sui", we set up MCAO rat model. Five indexes including Nestin, PSA-NCAM, MAP-2, GAP-43 and SYN38 were measured in situ hybridization and immunohistochemical methods to evaluate the effects of Fujian Tablet on the proliferation, migration, differentiation of neural stem cells, axonal growth and synapse formation. Other two indexes including trk-B, NOGO-A were used to assess the effects on the neurotropic factor and inhibitory factor.

以&肾生髓&的理论为依据，以MCAO大鼠为实验对象，利用原位杂交技术和免疫组织化学方法，分别以nestin、PSA-NCAM、MAP-2、GAP-43、突触素p38为指标，观察复健片对神经干细胞增殖、迁移、分化、轴突生长、突触形成的影响；分别以trk-B、NOGO-A为指标，观察复健片对神经生长营养因子、抑制因子的影响。

Postsynaptic dense area and the close relationship between synaptic plasticity are essential for the maintenance of synaptic function properly.

突触后致密区与突触可塑性的关系十分密切，对于维持突触发挥正常功能至关重要。

Whole-cell recordings were performed to record miniature excited postsynaptic currents after neurons were cultured for 1 week and 2 weeks.

培养到1周和2周时，采用膜片钳全细胞模式记录神经元突触内自发的微小兴奋性突触后电流。

RESULTS: Lidocaine inhibited both EPSP and the response foracetylcholine of the postsynaptic neuron.

结果：利多卡因同时抑制了兴奋性突触后电位和突触后神经元对乙酰胆碱的反应。

The transmission is conducted in the form of action potentials along the axon of DRG neuron to the presynaptic membrane in spinal dorsal horn. Action potential depolarizes the presynaptic membrane and activates the voltage-dependent Ca〓 channel. The influx of Ca〓 then triggers the release of neurotransmitter.

外界感觉信息以动作电位的形式沿DRG细胞轴突由外周传向DRG细胞在脊髓背角的突触前膜，导致细胞膜去极化，引起电压依赖性〓通道的开放，〓内流介导突触前膜神经递质的释放，从而完成感觉信息由外周向脊髓的传递。

In fact, BDNF potentiates intracellular Ca~(2+) release presynaptically and BDNF-induced TrkB activation also results in phosphorylation of synapsin I via mitoen activated protein kinase, which increases the number of synaptic vesicles available for release.

事实上，BDNF能促进突触前细胞内Ca~(2+)的释放，TrkB的激活也能通过有丝分裂活化蛋白激酶，引起突触素I的磷酸化，进而增加可释放的突触囊泡的数量。

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％。
