Studies on statistical properties of spontaneous spike trains of single auditory nerve have shown that the distributing patterns of interval in spike trains represent Poisson distribution. Since Poisson distribution is one of the simplest stochastic processes, previous studies on spontaneous spike trains of single auditory nerve were performed primarily by assuming them as stochastic processes. Recently, further studies on nonlinear dynamic system show that we have not enough evidence to demonstrate the process, whose distribution of probability density is exponential, is Poisson process.

中文题名豚鼠听神经单纤维放电序列的非线性特性分析副题名外文题名 Analysis on nonlinear properties in spike trains of single auditory nerve fiber in guinea pig 论文作者林龙年导师孙心德教授学科专业生理学研究领域\研究方向听觉神经生物学学位级别博士学位授予单位华东师范大学学位授予日期2001 论文页码总数91页关键词听神经听觉神经生理豚鼠馆藏号BSLW /2001 /Q42 /41 对听神经单纤维自发放电序列的统计特性研究表明，听神经单纤维放电间隔呈泊松分布，而泊松过程是最简单的随机过程之一，因此以往的研究主要将听神经单纤维自发放电序列作为随机过程来处理。

"This study raises the possibility that androgen replacement therapy might lower the risk for Alzheimer's, but this is far from proen," says Sam Gandy, MD, PhD, chair of the Alzheimer's Association's Medical and Scientific Adisory Council and director of the Farber Institute for Neurosciences at Thomas Jefferson Uniersity."Because testosterone is rapidly conerted to estrogen after entry into neurons, the new data are logical, and they doetail well with historical data."

"这项研究增加了雄激素补充疗法降低阿尔次海默危险性的可能，但是里真正的证实路还很长，"阿尔次海默医学协会和科学咨询委员会的**，Thomas Jefferson大学的神经病学Farber协会的主任，医学博士，公共卫生学博士Sam Gandy说，"因为雄激素在进入神经元后迅速降解为雌激素，新的研究资料还有局限性，然而他们的研究结果与历史上研究的结果很吻合。"

"The results of Dr. Felice's study are consistent with the findings of 7 published studies specifically designed to test the hypothesis that easier access to EC promotes risk-taking," Dr. Trussell told Medscape."All of these studies showed that easier access did not result in more unprotected sex and did not reduce the use of regular contraceptive methods."

Trussell医师向Medscape表示，Felice医师研究的结果和7项发表的研究发现一致，那7项研究特别是设计来检验，易於取得EC是否会让高危险性行为比例升高的假设；这些所有的研究显示，EC的容易取得EC并不会造成更多未防护的性行为，且不会减少一般避孕法的使用。
