改变行为的能力很可能取决于大脑突触的选择性增强和减弱。突触可塑性的细胞模型、长时程增强(LTP)和突触强度抑制(LTD)可分别通过突触AMPA受体(AMPAR)的插入或移除来表达。我们在这里概述了一些研究,这些研究使用动物模型来表明,这种AMPAR交易是几种经验驱动的现象的基础-从神经元电路形成到行为的改变。我们认为,监测和操纵突触AMPAR的运输是研究动物模型认知功能和功能障碍的一种有吸引力的手段。
The ability to change behavior likely depends on the selective strengthening and weakening of brain synapses. The cellular models of synaptic plasticity, long-term potentiation (LTP) and depression (LTD) of synaptic strength, can be expressed by the synaptic insertion or removal of AMPA receptors (AMPARs), respectively. We here present an overview of studies that have used animal models to show that such AMPAR trafficking underlies several experience-driven phenomena—from neuronal circuit formation to the modification of behavior. We argue that monitoring and manipulating synaptic AMPAR trafficking represents an attractive means to study cognitive function and dysfunction in animal models.
