  text: Hippocampus is needed for both spatial working and reference memories. Here,
    using a radial eight-arm maze, we examined how the combined demand on these memories
    influenced CA1 place cell assemblies while reference memories were partially updated.
    This was contrasted with control tasks requiring only working memory or the update
    of reference memory. Reference memory update led to the reward-directed place
    field shifts at newly rewarded arms and to the gradual strengthening of firing
    in passes between newly rewarded arms but not between those passes that included
    a familiar-rewarded arm. At the maze center, transient network synchronization
    periods preferentially replayed trajectories of the next chosen arm in reference
    memory tasks but the previously visited arm in the working memory task. Hence,
    reference memory demand was uniquely associated with a gradual, goal novelty-related
    reorganization of place cell assemblies and with trajectory replay that reflected
    the animal's decision of which arm to visit next.
