前瞻记忆是指对预定事件或行为的记忆。本文总结了前瞻记忆脑机制的相关文献,介绍了前额皮层、丘脑、内侧颞叶等脑区域在前瞻记忆中的作用,并通过分析注意缺陷多动障碍儿童、老年痴呆症患者、酒精依赖症和内侧颞叶癫痫患者前瞻记忆的表现,从临床角度深入探讨了前瞻记忆神经机制问题。证据表明,前额皮层参与前瞻记忆的编码、提取和监控过程,与意向保持也有密切的关系;丘脑与意向的执行有关,与前额叶的互动在前瞻记忆监控中起着重要作用;内侧颞叶与编码来源的提取和意向的激活都有密切的关系。研究认为前额皮层在前瞻记忆加工过程中起着核心的作用,同时与丘脑、内侧颞叶等区域相互作用,共同成为前瞻记忆编码、保持、提取、执行的神经基础。
Prospective memory refers to the memory of scheduled events or behaviors. This review summarizes the relevant literature on prospective memory brain mechanisms, introduces the role of the prefrontal cortex, thalamus, medial temporal lobe and other brain regions in prospective memory. By analyzing children with ADHD, Alzheimer’s disease, alcohol dependence and Medial temporal lobe epilepsy patients with prospective memory performance, from a clinical perspective in-depth discussion of prospective memory neurological problems. The evidence suggests that the prefrontal cortex involved in the process of encoding, extracting and monitoring prospective memory is also closely related to the intention to maintain; the thalamus is associated with the execution of the intention and the interaction with the prefrontal cortex plays an important role in prospective memory monitoring; the medial temporal lobe and The extraction of source code and the activation of intention are closely related. The study suggests that the prefrontal cortex plays a central role in prospective memory processing and interacts with regions such as the thalamus and medial temporal lobe to form the neural basis of prospective memory encoding, retention, extraction and execution.
