Described the real pyramidal and extrapyramidal neural networks of the mammalian brain, realizing asbehavior, motor control and involved in learning and memory. The algorithm of postsynaptic excitatory glutamatergic synapses plasticity analyzed, which leads to the modification and storage for a long time, the efficiency of synaptic transmission --ong-term potentiation, long-term depression. Analyzed the mechanisms of plasticity allosteric GABAA(-)redcptors. Described the molecular and cellular mechanisms of the trafficking of GABAA(-)receptors and its role in the dynamic modulation of neuronal inhibition. Analyzed molecular and cellular plasticity algorithm of allosteric GABAA(-)receptors. Discussed hypoth-sis update neural networks that is realized on a molecular level with the internalization and recycling mechanism specific GABAA(-)receptor cluster. It is assumed that the process of transfer from the memory stage storage to the stage of working memory. Deactualization of neural network, which is implemented at the molecular level by the mechanism of internalization specific cluster of GABAA(-)receptor, is a pro-ess of transferring from stage of working or random access memory in the storage stage.
描述了哺乳动物大脑中的真实锥体和锥体外神经网络,其实现行为、运动控制并参与学习和记忆。分析了突触后兴奋性谷氨酸能突触可塑性的算法,该算法导致突触传递效率的长期修饰和存储——长时程增强、长时程抑制。分析了变构GABAA(-)受体的可塑性机制。描述了GABAA(-)受体运输的分子和细胞机制及其在神经元抑制动态调节中的作用。分析了变构GABAA(-)受体的分子和细胞可塑性算法。讨论了通过特定GABAA(-)受体簇的内化和再循环机制在分子水平上实现的神经网络假设更新。假定从记忆阶段存储到工作记忆阶段的转移过程。神经网络的失活是通过特定GABAA(-)受体簇的内化机制在分子水平上实现的,是从工作或随机存取记忆阶段转移到存储阶段的过程。
