工作记忆（Working Memory，WM）是一种重要的认知功能，是我们进行日常活动所必需的。本综述简要介绍了最被接受的模型背后的WM和参与其处理的神经网络。本文就儿童期、青少年期和青年期的神经生理机制随年龄的变化作一综述。使用行为学、神经影像学和电生理学技术的研究显示了WM在整个发育过程中的进展。本综述的重点是WM操作的基本过程的神经生理学，如脑电图衍生的信号所示，为了利用这种技术的优良的时间分辨率。儿童和成人使用相似的大脑机制和区域来编码、识别和保持刺激并更新WM内容，尽管成人更依赖于前部部位。WM大脑处理的功能重组发生在青少年时期的可能性，并将部分证明在青少年时期出现的精神病理的高患病率。
Working memory (WM) is an important cognitive function that is necessary to perform our daily activities. The present review briefly describes the most accepted models underlying WM and the neural networks involved in its processing. The review focuses on how the neurophysiological mechanisms develop with age in the periods from childhood to adolescence and young adulthood. Studies using behavioral, neuroimaging, and electrophysiological techniques showed the progress of WM throughout the development. The present review focuses on the neurophysiology of the basic processes underlying WM operations, as indicated by electroencephalogram-derived signals, in order to take advantage of the excellent time resolution of this technique. Children and adults use similar cerebral mechanisms and areas to encode, recognize, and keep the stimuli in memory and update the WM contents, although adults rely more on anterior sites. The possibility that a functional reorganization of WM brain processing occurs around the adolescent period is suggested, and would partly justify the high prevalence of the emergence of mental pathology in the adolescent period.
