海马体在清醒状态下同时重放多条空间轨迹
Simultaneous awake replay of multiple spatial representations
AI 导读
Mou 和 Ji 发现,在观察学习任务中,大鼠海马位置细胞在获取奖励时会对多条轨迹进行同时重放。这种同时重放反映了任务的空间结构与奖励位置,优先重放正确轨迹,且与任务表现和皮层活动的相关性高于单条重放。
摘要
Mou and Ji demonstrate that hippocampal place cell activity representing multiple trajectories are simultaneously replayed during reward consumption in an observational learning task. Simultaneous replay reflects the spatial structure and reward sites in the task, prioritizes correct trajectories, and correlates more with task performance and cortical activity than single replay.
