BACKGROUND: It has been demonstrated that dopamine and acetylcholine are the main neurotransmitters that affect time perception, which is also affected by other neurotransmitters. OBJECTIVE: To summarize how the neurotransmitter affect the time perception, and put forward the perspectives for further study on time perception. RETRIEVE STRATEGY: An online search for related literatures published in English was conducted in Elsevier SDOL (ScienceDirect Online) database from May 1990 to March 2007 using key words of “timing neurotransmitter”. Totally 69 literatures were collected, and they were primarily checked. Inclusive criteria: Reviews and experimental studies; correlative studies of timing neurotransmitter. Exclusive criteria: Repeated studies. LITERATURE EVALUATION: The literatures were mainly sourced from Cognitive Brain Research and Neuroscience, and they were analyzed according to the inclusive criteria. Nineteen of them were involved, and all were experimental studies and reviews. DATA SYNTHESIS: The studies on time perception are developed mainly concentrating on dopamine and acetylcholine. Dopamine D2 receptors mainly affect the speed of internal clock. Dopamine receptors play an important role in both timing excitation and inhibition, which suggests the bi-directional regulation of dopamine. Injection of dopamine agonist can affect the attention to timing information. Injection of BW813U (antagonist of acetylcholine) can induce memory disorder, which indicates the effect of acetylcholine on timing memory, and further study shows that it is the effect of acetylcholine in precentral medial area. In a word, the study on the neurotransmitters affecting time perception is still at the primary stage. CONCLUSION: Dopamine and acetylcholine are the neurotransmitters known to be related to time perception. Dopamine in the basal ganglia is related to internal-clock in the range of seconds and minutes; Acetylcholine in prefrontal cortex is related to the mechanisms of temporal memory and attention. Studies of neurotransmitter provide an approach to acknowledge on the neuromechanism of time perception.

摘 要 私德教育是道德教育创新的突破口。私德教育是德育的基础,是社会主义现代化建设的迫切需要,是整个德育理论与实践的薄弱环节。加强私德教育,必须更新观念,重新认识公与私及二者之间的关系,重新认识私德教育与公德教育之间的关系。加强私德教育,必须对私德教育的内容、途径和方法进行创新。  关 键 词 私德教育;德育创新;突破口  作者简介 秦虹,天津市教育科学研究院研究员;张武升,天津市教育科学研

<正> 资金短缺是经济不发达最集中的表现之一。无论是一般欠发达国家,还是像中国这样的发展中社会主义国家,无论这些国家的经济制度和经济机制有多么大的差别,只要是处于人均国民收入水平低下的发展阶段,都难以摆脱经济发展资金不足的困境。而且,除了极少数可以获得某种特殊条件的国家之外,经济发展的加速往往形成更大的资金需求,从而进一步加剧资金短缺。如何为经济发展筹集必要的资金,是经济科学研究的一个重大理论和实践问题。《经济发展与宏观筹资》(以下简称《筹资》)一书,是我国学者对这一课题进行系统研究的一部开
