Hippocampal dynamics associated with directed information foraging. (A) VTE-like dynamics in the hippocampus are non-local representations that occur at choice points. While the animal pauses at the choice point (the bottom-center of the box), spatial representations in the hippocampus move ahead of the animal, following potential trajectories toward the different reward source locations. The spiking activity associated with these place cell dynamics is shown at right. (B) Map-switching is a representational dynamic in which place cell ensembles alternate between two maps. An initial map of place fields (left, top) can be divided into different maps (right) by identifying two or more sets of temporally non-overlapping ensemble spiking activity (left, bottom). These maps often reflect different task components.
