查询词典 synapse

Sperry showed that the regenerated retinal axons always innervated the original sites of termination in the optic tectum. This experiment strongly disprove the resonance hypotheses proposed by Paul Weiss, who suggested that the nerve growth and synapse formation are largely random events, and the precision of connections between nerve cells emerged by selectively eliminating the inappropriate connections, only at later developmental stage.

Sperry的实验在支持Cajal假说的基础上，进一步明确发育过程中轴突的生长及突触的形成具有内在决定性，并且有力地反驳了当时占主流地位的由Paul Weiss于1930～40年代提出的resonance hypothesis，后者认为轴突的生长和突触的形成大多是一些随机事件，成年脑中的精确联系是通过对随机形成的不恰当联系进行选择地消除形成的。

Using sucrose-gap recordings of synaptic transmission across the cockroach cercal nerve-giant fiber synapse,it was observed that the excitatory postsynapic potential was blocked by 0.1 g/L Celangulin Ⅳ after 72 min of medication.

甘露醇间隙法对美洲大蠊（Periplaneta americana中枢神经离体标本兴奋性突触后电位（EPSP的测定表明，质量浓度为0.1 g/L的苦皮藤素Ⅳ在用药后72 min阻断了EPSP。

A synapse is a junction between the axon and dendrites of two neurons.

许多神经元内的轴突被包裹在髓鞘内。

Based on the stability theory of dynamical system, numerical computation of bifurcation diagram and the largest Lyapunov exponent of the linearized systems, the synchronization dynamics of coupled fast spike neurons with excitory chemical synapse was studied.

基于动力系统的稳定性理论、数值计算分岔图和线性化系统的最大Lyapunov指数，研究了经兴奋性化学耦合的快峰神经元的同步动力学。

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。

Results: Fujian Tablet could increase the expression of neurotropic factor and decrease that of inhibitory factor. It promoted proliferation, migration, differentiation of neural stem cells, axonal growth and synapse formation remarkably.

结果：复健片可增加神经生长营养因子表达，减少抑制因子表达，对神经元增殖、迁移、分化，轴突延伸、突触形成等有明显促进作用。

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。
