学习是获得新知识或技能的过程,而记忆是将这些知识或技能编码存储以及随后读出的过程。记忆是大脑的高级功能,受多种因素调控,应激就是其中一种常见的影响因素。有研究[1]发现强烈、长期、不可控的恶性应激可以导致记忆受损;轻微、短暂、可控制的良性应激可以促进情感和智能的发育。应激对记忆的不同影响是近年来研究的热点,因此本文从糖皮质激素、去甲肾上腺素、5-羟色胺、谷氨酸和雌激素等神经递质方面对应激影响记忆的可能作用机制加以综述。
Learning is the process of acquiring new knowledge or skills, and memory is the process of encoding and storing these knowledge or skills and then reading them out. Memory is a high-level function of the brain and is regulated by many factors. Stress is one of the most common factors. Some studies [1] found that strong, long-term, uncontrollable malignant stress can lead to memory impairment; mild, transient and controlled benign stress can promote emotional and intellectual development. Different effects of stress on memory are hot topics in recent years. Therefore, the possible mechanisms of stress-induced memory in neurotransmitters, such as glucocorticoids, norepinephrine, serotonin, glutamate and estrogen, Summary.
