A growing body of research suggests that rats represent and remember specific earlier events from the past. An important criterion for validating a rodent model of episodic memory is to establish that the content of the representation is about a specific event in the past rather than vague information about remoteness. Recent evidence suggests that rats may also represent events that are anticipated to occur in the future. An important capacity afforded by a representation of the future is the ability to plan for the occurrence of a future event. However, relatively little is known about the content of represented future events and the cognitive mechanisms that may support planning. This article reviews evidence that rats remember specific earlier events from the past, represent events that are anticipated to occur in the future, and develops criteria for validating a rodent model of future planning. These criteria include representing a specific time in the future, the ability to temporarily disengage from a plan and reactivate the plan at an appropriate time in the future, and flexibility to deploy a plan in novel conditions.
越来越多的研究表明，大鼠能够表征并记住过去特定的早期事件。验证情景记忆啮齿动物模型的一个重要标准是确定表征的内容是关于过去的特定事件，而不是关于久远性的模糊信息。最近的证据表明，大鼠可能还能表征预计在未来发生的事件。对未来的表征所赋予的一项重要能力是为未来事件的发生制定计划的能力。然而，对于所表征的未来事件的内容以及可能支持计划制定的认知机制，人们了解得相对较少。本文回顾了大鼠记住过去特定早期事件、表征预计在未来发生的事件的证据，并制定了验证未来计划啮齿动物模型的标准。这些标准包括表征未来的特定时间、在未来适当的时候暂时脱离计划并重新激活该计划的能力，以及在新情况下灵活部署计划的能力。
