These channels coupled the membrane excitability to intracellular ca2 + concentration and were believed to play an important role in intracellular signaling . ( 2 ) both unitary conductance and po of bkca channel were markedly sensitive to temperature 通道可将细胞信使cah的调节与神经元电兴奋性的调节有机的偶联起来，进一步确定了其在细胞信号转导中的重要作用。
The first approach is based on the use of protocols of stimulation that increase cortical excitability , targeting the hemisphere in which the stroke occurred in order to enhance the output of the motor cortex and the response to physiotherapy 第一种方法是建立在刺激能够增强皮质的兴奋性这样的刺激设计应用，目标是卒中发生侧半球，来增强运动皮质的输出和对理疗的应答。
Conclusions : our results suggest that segmental and heterosegmental conditionings of nwr are mediated by myelinated muscle afferents engaging central inhibitory mechanisms rather than direct changes in the excitability of motor neurons 结论我们的结果说明nwr的节段性制约刺激和异源节段性制约刺激是经有髓传入纤维介导，通过中枢性抑制机理起作用，而不是直接引起运动神经元兴奋性的变化。
In the first part of our studies , we observed the morphologic changes of pc12 cells respectively after 24h , 48h , 72h ' s culture in aocm , the expression of neuronal specific protein ( 3 - tubuliniii after 3d ' s culture , and the membrane excitability after 6d ' s culture 在本实验的第一部分中，我们观察了aocm培养24小时， 48小时， 72小时时pc12细胞的形态学变化；培养3天时神经元特异蛋白? tubulin的表达；培养6天细胞膜兴奋性的变化。
Intracellular ca2 + serves as a ubiquitous second messenger in nerve cells . fluctuations of [ ca2 + ] termed " calcium signals " regulate a variety of intracellular events such as excitability , neurotransmitter release , synaptic plasticity , gene expression , development and differentiation 神经细胞内钙离子不仅是一种重要的第二信使，而且对神经细胞的其它功能也具有重要的调节作用，因此，有必要在完整神经细胞上准确测定钙离子的动态变化、运动方式及梯差分布。
Children beginning therr basic training have a high level of excitability , and know little about the importance of madtering proper techniques , so they always concentrate on doing their best to shot to the other half of the table by ignoring the essentials of technique 刚开始接受训练的少年儿童，兴奋性高，对掌握正确技术要领的重要性不甚明确，因而，往往把注意力仅仅集中到尽可能f硕士学位论文型r xk盯厂s刀ie扔地把球击到对方台面上，而忽视了动作的许多要领。
Myocardial bioelectric phenomena and their mechanism , the characters of excitation transmission in heart ; the periodicity changes and their characters of myocardial excitability , autorhythmicity and pacemaker of heart ; pumping function of heart and evaluation ; the concept , mechanism and influencing factors of arterial blood pressure ; carotid sinus and aortic arch baroreceptor reflex 心肌细胞（工作细胞和自律细胞）的生物电现象及其形成的机制，心内兴奋传播的特点；心肌兴奋性的周期性变化及其特点，自律性和心脏的起搏点；心脏的泵血功能及其评价；动脉血压的概念、形成机制、影响因素；颈动脉窦和主动脉弓压力感受性反射。
The second approach is based on the use of protocols of stimulation that suppress cortical excitability , targeting the intact hemisphere in order to counteract the imbalance due to the increased interhemispheric inhibition onto the lesioned cortex , and reducing the potential negative interference of the intact hemisphere with the function of the affected one 第二种方法是建立在抑制皮质的兴奋性这样的刺激设计应用，目标是未受累侧半球，来阻碍由于受损皮质半球内抑制而增强的不平衡，减少未受累半球对受累侧功能潜在的负干扰。
