Current interpretations of hippocampal memory function are blind to the fact that viewing behaviors are pervasive and complicate the relationships among perception, behavior, memory, and brain activity. For example, hippocampal activity and associative memory demands increase with stimulus complexity. Stimulus complexity also strongly modulates viewing. Associative processing and viewing thus are often confounded, rendering interpretation of hippocampal activity ambiguous. Similar considerations challenge many accounts of hippocampal function. To explain relationships between memory and viewing, we propose that the hippocampus supports the online memory demands necessary to guide visual exploration. The hippocampus thus orchestrates memory-guided exploration that unfolds over time to build coherent memories. This new perspective on hippocampal function harmonizes with the fact that memory formation and exploratory viewing are tightly intertwined.

仔细观察海马体和记忆

当前对海马记忆功能的解释忽略了这样一个事实,即观看行为无处不在,并使感知、行为、记忆和大脑活动之间的关系复杂化。例如,海马活动和联想记忆需求随着刺激的复杂性而增加。刺激复杂性也强烈地调节观看。因此,联想处理和观察经常被混淆,导致海马活动的解释模棱两可。类似的考虑挑战了许多关于海马功能的解释。为了解释记忆和观看之间的关系,我们建议海马体支持指导视觉探索所需的在线记忆需求。因此,海马体协调记忆引导的探索,随着时间的推移展开以建立连贯的记忆。
