动作信息被整合到概念空间的内生表征中，并反映在眼球运动中
Action information is integrated into entorhinal representations of conceptual space and is reflected in eye movements.
摘要(中文译文)
海马-内嗅系统表征空间和非空间认知地图中状态之间的关系。理解这些记忆表征如何被用于认知的关键，在于确定构成状态转换基础的动作是否被整合到内嗅认知地图中。参与者学习使用不同的动作在状态之间进行转换，这些动作被操作化为数学运算。我们发现，内嗅皮层表征了跨状态的可供性动作。这种动作表征无法由任务空间的其他属性来解释，例如状态之间的链接距离或反应时。此外，注视行为在水平轴上反映了可供性动作的方向，而这种偏侧化的强度既预测了表现，也预测了内嗅模式的相似性，提示注视行为与用于导航概念空间的神经认知机制之间存在联系。总之，本研究首次提供了动作信息被整合到概念空间的眼动和内嗅表征中的证据，提示这些表征可能不仅仅映射经验，还提供了关于如何探索知识的信息。
Abstract
The hippocampal-entorhinal system represents relations between states in spatial and nonspatial cognitive maps. Critical to understanding how these memory representations are used for cognition is to determine whether the actions underlying state transitions are incorporated in entorhinal cognitive maps. Participants learned to transition between states using different actions, operationalized as mathematical operations. We found that the entorhinal cortex represented the afforded actions across the states. This action representation was not explained by other properties of the task space, such as link distance between the states or reaction times. Furthermore, gaze behavior reflected the direction of afforded actions in the horizontal axis, and the strength of this lateralization predicted both performance and entorhinal pattern similarities, suggesting a link between gaze behavior and neurocognitive mechanisms for navigating conceptual spaces. In sum, this study provides first evidence for the integration of action information into ocular and entorhinal representations of conceptual spaces, suggesting that these may not just map out experiences, but provide information about how to explore knowledge.
