Synaptic modification

The question is whether there is correlation between synaptic depression and modification of global excitability.

问题是与长时程增强互补的、长时程抑制（LTD）现象是否与突触前整体兴奋性相关。

Activity dependent synaptic modification is critical for the development and function of nervous system, the extent and direction of modification may depend on the precise timing of pre-and post-synaptic action potentials.

由动作引起的突触变化对神经系统的生长和功能是十分重要的，其变化的程度和方向是由突触前后动作电位的精确定时引起的。

And the reinforced Hebb Synaptic Modification is used as the self-learning method to make the neurons in different fields to respond to the different stimulus in the best way.

在输出域中针对控制任务采用强化Hebb学习机制，实现不同的神经元以最佳方式响应不同性质的信号刺激。

Presynaptic [ Ca 2+] I could influence the replacing of presynaptic depressed vesicles, as well as encode the precise relative timing of presynaptic input and postsynaptic activity and generate long term synaptic modification of opposite polarity ( LTP or LTD).

突触前[Ca2+]i可以影响被抑制的突触前膜囊泡的更新，并准确编码突触前和突触后信息，产生截然相反的长时程突触修饰（LTP或LTD）。

Objective: The membrane properties and synaptic transmission of neurons in rat visual cortex were examined to explore modification of these characteristics by visual experience during development.

目的：研究大鼠不同发育阶段视皮层各层次神经元的被动膜学特性和突触传递特性，探讨视觉经验在视皮层发育过程中对神经元突触的修饰作用。
