One of the properties of the nervous system is the use-dependent plasticity of neural circuits. The structure and function of neural circuits are susceptible to changes induced by prior neuronal activity, as reflected by short- and long-term modifications of synaptic efficacy and neuronal excitability. Regarded as the most attractive cellular mechanism underlying higher cognitive functions such as learning and memory, activity-dependent synaptic plasticity has been in the spotlight of modern neuroscience since 1973 when activity-induced long-term potentiation (LTP) of hippocampal synapses was first discovered. Over the last 10 years, Chinese neuroscientists have made notable contributions to the study of the cellular and molecular mechanisms of synaptic plasticity, as well as of the plasticity beyond synapses, including activity-dependent changes in intrinsic neuronal excitability, dendritic integration functions, neuron-glia signaling, and neural network activity. This work highlight some of these significant findings.
神经系统的特性之一是神经回路的使用依赖性可塑性。神经回路的结构和功能易受到先前神经元活动诱导的变化的影响,这反映在突触效能和神经元兴奋性的短期和长期改变上。作为学习和记忆等高级认知功能的最具吸引力的细胞机制,活动依赖性突触可塑性自 1973 年首次发现海马突触的活动诱导长时程增强(LTP)以来,一直是现代神经科学的焦点。在过去的 10 年中,中国神经科学家在突触可塑性的细胞和分子机制以及突触外可塑性的研究方面做出了显著贡献,包括神经元内在兴奋性、树突整合功能、神经元-胶质细胞信号传递和神经网络活动的活动依赖性变化。这项工作强调了其中一些重要发现。
