Abstract

Inhibition of neuronal activity in the medial septum stops grid cells in the medial entorhinal cortex from firing in a grid.

  • Theta oscillations are not necessary for the emergence of the place code but play a major role in organizing place cell activity into temporal sequences that map available space and episodic events.

    “Theta oscillations—although not necessary for the emergence of the place code21,22—play a major role in organizing place cell activity into temporal sequences that map the available space (and, similarly, episodic events4,23,24).”

    From Place and behavioral modulation of hippocampal neurons during immobility (2026) · cites this paper as [21]

    The paper’s discussion (page not provided) says that companion findings showed spared hippocampal place-cell specificity during septal inactivation, and that the combined data suggest grid-cell periodicity is not essential for place-cell responses in familiar environments. That supports a narrower point than the attributed claim: it does not directly establish that theta is unnecessary for the emergence of a place code. The sentence’s separate claim about temporal sequences is attached to other citations, not this source. (LLM, conf=0.84)

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.
