记忆神经环路的研究进展

Research progress on neural circuits of memory

记忆是脑的高级神经功能,根据记忆持续的时间可分为感觉记忆、短时记忆和长时记忆。记忆是脑内神经核团及其互相之间联系形成的神经环路编码,不同的神经环路可能参与一种或多种记忆类型。高度特异性的神经环路和细胞功能干预技术(如光遗传学和化学遗传学技术等)的发展极大地促进了人们对记忆神经环路机制的认识。现就几种记忆的相关脑区及神经环路做一综述。

Memory is the advanced neurological function of the brain.According to the duration of memory,it can be divided into sensory memory,short-term memory and long-term memory.Memory is encoded by the neural circuits formed by the nucleis in the brain and their connections with each other.Different neural circuits may participate in one or more memory types.The development of highly specific neural circuits and cell function intervention techniques(such as optogenetics and chemical genetics techniques)has greatly promoted people’s recognition for the mechanism of memory neural circuits.This article reviews several memory related brain regions and neural circuits.
