将来事件情节模拟的神经基础

人类是能够展望未来的。近年来,将来事件情节模拟的神经机制问题已经成为了认知神经科学领域的一个热点。大量神经心理学和脑成像的研究发现,大脑中有特定的核心脑系统参与了将来事件的情节模拟。该系统主要包括前额叶、内侧颞叶、后扣带皮层和压后皮层。对于将来事件情节模拟的研究结果有三种理论解释,即情节模拟假设、自我投射假设和场景建构假设。然而,要真正揭示将来事件情节模拟的本质,还有许多问题需要进一步澄清。

The Neural Basis of Episodic Simulation of Future Events

Human beings are capable of envisioning the future.Recently,the research about the neural basis of episodic simulation of future events has become a hot issue in the field of cognitive neuroscience.Lots of studies of imaging future in the filed of neuropsychology and brain imaging reveal a specific core brain system which is found to be involved in the process of episodic simulation of future events.The system mainly includes the prefrontal,medial temporal lobe,posterior cingulate cortex,and retrosplenial cortex.There are three theories to interpret the findings of studies about episodic simulation of future events,including constructive episodic simulation hypothesis,self-projection hypothesis and scene construction hypothesis.To understand the nature of episodic simulation of future events,however,many questions need to be investigated further in the future.
