NMDA(N-methyl-D-aspartate) receptors are a subtype of excitatory transmitters-glutamate receptor which belong to a heteromeric ligand-gated ionotropic receptors and play an important role in many complex physiological and pathological processes, such as nerve development, neuronal excitatory synaptic transmission, synaptic plasticity, central sensitization and neuronal death.

NMDA(N-methyl-D-aspartate)受体是兴奋性神经递质谷氨酸受体的一种亚型，是一种异聚体配体门控型离子通道，参与体内神经发育、神经元的兴奋性突触传递、突触可塑性、中枢敏化、神经元死亡等多种不同的生理和病理过程。

Glutamate is the major excitatory neurotransmitter in the mammalian brain and key mediator of intracellular communication, plasticity, growth and differentiation. NMDA receptors is one kind of Glutamate receptors.

N-甲基-D-天门冬氨酸受体是一种门控离子通道复合物，作为兴奋性氨基酸受体之一，主要分布于大脑皮层、海马、纹状体等部位，是兴奋性氨基酸递质传递的重要基础，同时是维持中枢神经系统功能正常的关键因素。

In this dissertation,a new mechanism of stochastic resonance in the excitablesystem is presented,and the relationship between the stochastic resonance inexcitable neurons and the dynamic bistability is reported for the first time.Thepresent study deals with the extension of the concept of stochastic resonance,which has been thoroughly examined in bistable and simple excitable system,to amore complex system.It may even open the door to a better understanding ofstochastic resonance in neural system since experimental evidence supports theextension of such bistability in vitro preparations.

本文提出了可兴奋性系统中一种新的随机共振机制，首次报道了可兴奋性神经元中随机共振和动态双稳态的关系，将以前的单纯讨论双稳系统或可兴奋系统中的随机共振推广到了可兴奋系统中有动态双稳态更复杂的情形，由于在神经元的实验中已有关于动态双稳态的报道，本文所提出的随机共振为理解神经元中随机共振的编码机制开启了新的途径。

Opioids decrease the activity of both excitatory and inhibitory neurons in the myenteric plexus.
