Abstract

Hippocampal place cells support spatial memory using sensory information from the environment and self-motion information to localize their firing fields. Currently, there is disagreement about whether CA1 place cells can use pure self-motion information to disambiguate different compartments in environments containing multiple visually identical compartments. Some studies report that place cells can disambiguate different compartments, while others report that they do not. Furthermore, while numerous studies have examined remapping, there has been little examination of remapping in different subregions of a single environment. Is remapping purely local or do place fields in neighboring, unaffected, regions detect the change? We recorded place cells as rats foraged across a 4-compartment environment and report 3 new findings. First, we find that, unlike studies in which rats foraged in 2 compartments, place fields showed a high degree of spatial repetition with a slight degree of rate-based discrimination. Second, this repetition does not diminish with extended experience. Third, remapping was found to be purely local for both geometric change and contextual change. Our results reveal the limited capacity of the path integrator to drive pattern separation in hippocampal representations, and suggest that doorways may play a privileged role in segmenting the neural representation of space.

  • It is not yet entirely conclusive that all goldfish neurons with border activity are functionally closer to BVCs than PCs, because some PCs can also exhibit PF duplications in parallel compartments.

    “Second, it is not yet entirely conclusive that all goldfish neurons with border activity are functionally closer to BVCs than PCs, because some PCs can also exhibit PF duplications in parallel compartments48–50.”
  • Geometric modifications are accompanied by more substantial changes in the firing patterns of place cells than are surface modifications, suggesting that HPC remapping actively supports the role of geometry in the stability of spatial representations.

  • Hippocampal place cells fired in analogous positions in geometrically identical environments learned in a single training session, even with proprioceptive and vestibular cues present.

    “similar results were observed in a recent rodent neurophysiology study which found that hippocampal place cells fired in analogous positions in geometrically identical environments that were learned in a single training session, even though these proprioceptive and vestibular cues were present45.”

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.
