突触

Routtenberg agrees with the view that it is the synapse that is modified in response to learning-associated activity, a position first articulated by Nobelist Ramony Cajal a century ago.

Routtenberg也认同突触（是由诺贝尔奖得主Ramony Cajal在一个世纪前发现的）可以被学习相关性激活所改变。

This method of weight changing between nodal point s is very similar to the readjustment of the stimulus signals by synapsis of the brain

这种改变节点间连接权重的方法类似于大脑的突触对刺激信号进行调节的现象

The acetylcholine,γ-aminobutyric acid and nitric oxide are major neurotransmitters for olfaction synaptic transmission in MB.

乙酰胆碱、γ-氨基丁酸和一氧化氮等是蘑菇体嗅觉突触传递的主要神经递质。

Complete resolution of detrusor overactivity was observed in 44% of BTX-A patients at 4 weeks, though this dropped to 25% by 24 weeks.

重链结构BTX对运动神经末梢突触前膜的结合及内化有关；轻链结构与BTX抑制神经递质的释放有关。

However, a growing number of studies suggest that excessive extracellular glutamate and resultant overstimulation of its receptors cause excitotoxic roles and lead to neuronal damage in several pathological conditions such as cerebral ischemia. Normally, the excitatory postsynaptic roles of glutamate are terminated by the activities of high-affinity sodium dependent glutamate transporters that locate on neuroglial cells and neurons near the synaptic cleft, which are thought to play important roles in inactivating released glutamate and keep it below toxic levels in the extracellular space.

在生理状态下，突触间隙中谷氨酸的清除取决于邻近神经胶质细胞及神经元上高亲和力、钠依赖性谷氨酸载体的活动，通过该载体的再摄取机制保持细胞外谷氨酸浓度于正常范围，这在预防谷氨酸的神经毒中起着重要的作用。

Ultimately, vulnerable groups of neurons atrophy and die in a process that may involve excitotoxicity (overstimulation of neurotransmitter receptors on neuronal surface membranes), collapse of calcium homeostasis, inflammation, and depletion of energy and growth factors. A form of apolipoprotein E, apoE4, contributes to the abnormal accumulation of A and tau, but probably also damages mitochondria and the cellular cytoskeleton. A , tau, apoE and -synuclein interact with many other molecules and modulate diverse signalling cascades that regulate neuronal activity and survival.

最后，易感神经元会萎缩直至死亡，原因可能有兴奋性中毒（神经递质对神经元表面受体的过度刺激引起），钙稳态失衡，炎症反应，能量和生长因子的耗尽。apoE4的产生可导致A肽和tau蛋白的异常聚合，可能也损害线粒体和细胞骨架。A肽、tau蛋白、apoE和突触核蛋白可与很多分子反应，也可调节不同信号级联反应，这些级联反应对于维持神经元活动性和生存性意义重大。
