兴奋性的

BACKGROUND: F-wave is a late muscle response which results from the antidromic activation of spinal motorneurones following peripheral nerve supramaximal electrical stimulation,and influenced by the balance of excitatory and inhibitory postsynaptic potentials on spinal motomeurons.

背景：F波是末梢神经接受最大电刺激，从肌肉诱发出来的后期合成活动电位之一，是脊髓运动神经元突触后电位的反映，对F波的研究已经被作为衡量脊髓运动神经元兴奋性的一种手段。

They show significantly elevated fluctuations of vestibular excitability, which correlate with the severity of vertigo symptoms.

他们显示前庭兴奋性的波动明显增加，这与眩晕的严重性是相关的。

Results:① there was significant difference in all personality traits except stableness and shrewdness among the three groups,(p 05). compared to the standardization samples, military pentathlon athletes were more outgoing, more dominant, more happy go lucky, bolder, tenser, but less suspicious, less apprehensive, and less self sufficient.② there was significant difference in the personality traits of outgoingness, happy go lucky and self sufficiency among the three grades of athletes (p 05). but the international master athletes scores of the personality traits varied little.

结果： ① 3组被试16个因子得分除稳定性和世故性外均存在显著性差异（p 05），方差主要来源于组间；军事五项运动员乐群性、恃强性、敢为性、紧张性和兴奋性较高，怀疑性、忧虑性和独立性较低（p 05）；②国际级健将，国家级健将和一般运动员仅在乐群性、兴奋性和独立性上存在显著差异（p 05），国际级运动员各因子得分变化较少，国家级和等级运动员的变化较大。

Cellular structure is simple and has intermediate neurons, which can survive a longer period in vitro. Amphibial sympathetic ganglions show various postsynaptic potential including fast excitatory postsynaptic potential. Slow inhibitory postsynaptic potential.Slow exeitatory postsyn...

两栖动物交感神经节表现出多种突触后电位，包括快兴奋性突触后电位，慢抑制性突触后电位，慢兴奋性突触后电位，晚期慢兴奋性突触后电位，同时还表现多种突触塑性，说明该神经节具有信息存储功能，因此，两栖动物交感神经节可作为研究学习与记忆的模型系统。

Overexcitability group included67cases whose threshold differences were over-1.57mA.

呈超兴奋性的患侧面神经属生理性传导阻滞的自然治愈群。

The volume of stimulant amino acid in the hypothalamic tuberal part of rat is dcreased,the volume of rejective amimo acid increased,the volume of Catecholamines drceased,the volume of the stimulant amino acid in spinal cord intermediolateralis,the rate of stimulant amino acid and rejective amimo acid,and the volume of Catechomamones dcreased,the volume of NE in spleen tissue dcreased,all of which means the irritability of sympathetic nervous circulus in spleen is restrained.

运动组大鼠下丘脑结节部兴奋性氨基酸含量下降，抑制性氨基酸含量上升，儿茶酚胺含量下降，脊髓中间外侧柱兴奋性氨基酸含量下降、兴奋性氨基酸/抑制性氨基酸下降、儿茶酚胺含量降低，脾组织内NE含量降低，提示有氧运动组大鼠的脾脏交感神经调节通路的兴奋性受到抑制。

Excitability of the motor cortex were assessed by rest threshold, central motor conduction time, central sile...

采用静息态阈值、中枢传导时间、中枢静息期和运动诱发电位的波幅作为评定大脑皮质兴奋性的指标。

METHODS: In rat hippocampal slices, whole cell patch clamprecordings were used to study anesthetic effects on CA1 neuronintrinsic excitability, and population spike recordings wereused to investigate effects on synaptically evoked discharge.

在大鼠海马脑片上采用全细胞膜片钳记录来研究麻醉药对CA1神经元自发兴奋性的作用；采用群峰电位记录来研究对突触诱发放电的作用。

The inhibition of A-current clearly contributed to the potentiating effects of CCK-8S on the whole neuronal excitability of VMH.

CCK-8S对IA电流的调节可能是其调控VMH神经元整体兴奋性的重要机制。

Cytoplasmic membrane potentials of cortex and nith and the parenchyma within the xylem, as measured with intracellular micro-electrods, range about 140 mV.

但是在高等植物中，兴奋性的研究仍然集中于敏感的和半敏感的植物，而对于大量的非敏感植物很少研究。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
