However, little is known about how SP alters the activity of the CVNs at synaptic level. 但在突触水平,对SP如何影响CVN的活动所知甚少。
This issue becomes particularly significant if considered under the background of epilepsy or seizures, since little is known about the firing behavior of the CVNs during epileptic attacks, which are well known to be related to decreased function of inhibitory neurotransmission. 这一问题如果放在癫痫病理背景下考虑,变得尤其重要。癫痫发作与抑制性突触传递下降有关,但癫痫发作时CVN的发放行为模式目前尚不知道。
The CVNs were identified by presence of fluorescence in brainstem slices and studied using patch-clamp. 在脑片用荧光鉴定CVN,并用膜片钳方法研究。
Since RS CVn-type binary was defined by Hall in 1976, the solar-type activity(" chromospheric activity "or" magnetic activity") of contact binaries interests many astronomic researchers. 自从1976年,Hall明确地提出RsCVn型双星的定义以来,密近双星的类太阳活动(也叫色球活动或磁活动)性质就引起众多天文工作者的极大兴趣。
The seizure-like activation of the CVNs was in synchrony with that of the hypoglossal motor neurons. CVN的这种痫样激活与舌下神经运动神经元的痫样放电同步。
These results have given new evidence that the CVNs might fire in a seizure-like pattern during epileptic attack, which might be responsible for the neurogenic ictal bradyarrhythmia, cardiac asystole, or even the sudden deaths of patients of epilepsy. 3. 这些结果提供了新的证据,提示癫痫时CVN可能以痫样模式发放。而这种发放模式可能与癫痫病人发作时的神经源性发作性心动过缓、心跳骤停、甚至猝死有关。
