建立突触释放过程中神经递质的时间和浓度分布是了解中枢神经系统神经元间通讯基本特性的重要一步。为了深入了解这一过程,人们进行了各种巧妙的尝试,但中央突触普遍难以接近、所用技术的内在局限性以及不同突触环境的自然多样性阻碍了对这一基本现象的全面描述。在这里,我们描述了许多实验和理论发现,这些发现有助于增进我们对神经递质释放各种特征的了解,以及新开发的工具,可以克服传统药理学方法的一些限制,并为描述突触传递的复杂机制带来新的动力。
Establishing the temporal and concentration profiles of neurotransmitters during synaptic release is an essential step towards understanding the basic properties of inter-neuronal communication in the central nervous system. A variety of ingenious attempts has been made to gain insights into this process, but the general inaccessibility of central synapses, intrinsic limitations of the techniques used, and natural variety of different synaptic environments have hindered a comprehensive description of this fundamental phenomenon. Here, we describe a number of experimental and theoretical findings that has been instrumental for advancing our knowledge of various features of neurotransmitter release, as well as newly developed tools that could overcome some limits of traditional pharmacological approaches and bring new impetus to the description of the complex mechanisms of synaptic transmission.
