兴奋性的

The present study was designed to investigate whether histamine is involved in the protective effect of carnosine on Aβ42-induced impairment in differentiated PC12 cells.

因此本实验的主要目的是检测肌肽对Aβ42诱导的神经兴奋性损伤是否具有保护作用，肌肽-组胺酸-组胺通路是否参与其保护机制，谷氨酸含量，NMDA受体表达及功能在这一过程中是否受到影响，最终阐明肌肽保护作用的具体机制。

vns may reduce the excitability of cerebral cortices by inhibiting the firing rates of trn so as to inhibit the formation and development of seizures.

本实验结果提示vns可能通过抑制trn神经元的放电，降低大脑皮层的兴奋性，从而抑制癫痫的形成及发展。

Excitatory neurons are orientation selective and driven by external inputs.

兴奋性神经元是方向选择性的，是靠外部输入的刺激驱动的。

After SCI, primary injury was caused by mechanical damage and incontinuity of the tissue and vessels, which will lead to a complex secondary injury process such as hemorrhage, inflammation and exitotoxicity et al.

SCI后血管和神经组织的机械性损坏和断裂引起原发性损伤，继而引发出血、炎症、兴奋性毒性等一系列复杂的损伤过程，导致继发性损伤的进一步扩大。

The synchronous oscillation and propagation and the forward problem of the nerval activities are the main contents of the dissertation.

对可兴奋性神经元的同步振荡及其传导以及神经电活动正问题的研究是论文的主要内容。

Chronic blockade of cortical culture activity increased the amplitude of miniature excitatory postsynaptic currents without changing their kinetics.

皮质培养活性的慢性阻抑会增加微兴奋性突触后电位的幅度而不改变它们的动力学。

The expression of N-methyl-D-aspartatereceptor subunit2B in the passaged NSCs was determined by im-munocytochemistry and Western blot.

谷氨酸是体内一种主要的兴奋性氨基酸，它的过度释放可通过NMDA受体导致神经元和神经胶质细胞的死亡［2］。

objective to investigate the difference of motor threshold between the depressed patients and normal volunteers, and analyze the change of cortical excitability in patients.

目的 了解抑郁症患者的运动阈值(motor threshold，mt)与正常人的差异，探讨抑郁症患者的皮层兴奋性变化。

Such mechanism may also account for the ultrastructural changes and loss of function in peptide containing afferent nerve ending. This has been suggested as an explanation for one form of desensitization, especially when peptide release was used as a measure of capsaicin-induced nerve activation.

细胞超微结构改变导致含有神经肽的感觉神经功能丧失也是作用机制之一；尤其是神经肽释放被用于测量辣椒碱介导的神经兴奋性时，该机制更被认为是神经失敏的另一种形式。

The central respiratory chemoreceptors that is widely distributed in medulla oblongata can adjust the excitability of the neurons located in respiratory center of brain stem by sensing the changes of pH and the concentration of CO2 in brain, therefore , it plays an important role in keeping acid-base balance rapidly and maintaining homeostasis in vivo.

脑内pH和CO2的变化通过中枢化学感受器(central chemoreceptors，CRCs)调节脑干呼吸中枢的兴奋性，其在快速调节机体酸碱平衡以及内环境稳定的过程中发挥着重要作用。
