Hippocampal place-cell sequences depict future paths to remembered goals

Abstract

Effective navigation requires planning extended routes to remembered goal locations. Hippocampal place cells have been proposed to have a role in navigational planning, but direct evidence has been lacking. Here we show that before goal-directed navigation in an open arena, the rat hippocampus generates brief sequences encoding spatial trajectories strongly biased to progress from the subject's current location to a known goal location. These sequences predict immediate future behaviour, even in cases in which the specific combination of start and goal locations is novel. These results indicate that hippocampal sequence events characterized previously in linearly constrained environments as 'replay' are also capable of supporting a goal-directed, trajectory-finding mechanism, which identifies important places and relevant behavioural paths, at specific times when memory retrieval is required, and in a manner that could be used to control subsequent navigational behaviour.

  • Representations of rewarded spatial locations are preferentially reactivated in both wake and sleep states, although there are also findings of a bias in the opposite direction.

    “representations of rewarded spatial locations are preferentially reactivated in both wake and sleep states, 80,81,[142][143][144] although there are also findings of a bias of reactivations in the opposite direction.”

    From Sleep—A brain-state serving systems memory consolidation (2023) · cites this paper as [144]

    The ‘Trajectory events over-represent a known goal location’ section reports that hippocampal events over-represented the rewarded HOME location during awake behavior. The paper mentions replay during sleep, but does not report preferential reactivation of rewarded locations during sleep. The citation appears before the separate clause about a bias in the opposite direction. (LLM, conf=0.88)

  • Both sleep and wake replay can represent knowledge about an environment and share anticipatory features, including offline pre-activations of trajectories entailing visible but yet unexplored paths and locations.

    “both sleep and wake replay can represent knowledge about an environment and also share anticipatory features, such that they can e.g., include offline ''pre-activations'' of trajectories entailing visible but yet unexplored paths and locations.”

    From Sleep—A brain-state serving systems memory consolidation (2023) · cites this paper as [144]

    The Abstract reports trajectory sequences that predict future behavior, including novel combinations of start and goal locations, and mentions replay during both sleep and wakefulness. The section ‘Trajectory events actively and flexibly reflect task demands’ specifies that the novel paths were over familiar terrain. The paper does not establish that sleep and wake replay both pre-activate visible but unexplored paths or locations. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • There is now an accumulating wealth of reports of the sort of neural response profile that would be predicted if an animal is evaluating a menu of internally represented actions and their consequences at critical decision points.

    “Along with these human studies, there is now an accumulating wealth of reports of the sort of neural response profile that would be predicted if indeed an animal is evaluating a menu of internally represented actions and their consequences at critical decision points.”

  • These forward sweeps are consistent with the idea that the subject is engaged in some form of deliberation regarding its future potential states and the worth thereof, for instance, being correlated with the subject's ultimate choices.

    “They do so in a manner consistent with the idea that the subject is engaged in some form of deliberation regarding its future potential states and the worth thereof (Johnson and Redish, 2007; Pfeiffer and Foster, 2013; van der Meer and Redish, 2009), for instance, being correlated with the subject’s ultimate choices.”

  • At decision points such as a branch point in a maze, hippocampal place cell responses can be observed to sweep forward from the actual location of the subject.

    “In particular, at decision points such as a branch point in a maze, hippocampal place cell responses can be observed to sweep forward from the actual location of the subject.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
