Abstract

Navigation requires not only the execution of locomotor programs but also high arousal and real-time retrieval of spatial memory that is often associated with hippocampal theta oscillations. However, the neural circuits for coordinately controlling these important processes remain to be fully dissected. Here we show that the activity of the neuromedin B (NMB) neurons in the nucleus incertus (NI) is tightly correlated with mouse locomotor speed, arousal level, and hippocampal theta power. These processes are reversibly suppressed by optogenetic inhibition and rapidly promoted by optogenetic stimulation of NI NMB neurons. These neurons form reciprocal connections with several subcortical areas associated with arousal, theta oscillation, and premotor processing. Their projections to multiple downstream stations regulate locomotion and hippocampal theta, with the projection to the medial septum being particularly important for promoting arousal. Therefore, NI NMB neurons functionally impact the neural circuit for navigation control according to particular brains states.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Locomotion is a homogeneous behavioral state tightly coupled to arousal.

    “This is because locomotion—where place cell activity has been classically characterized—is a homogeneous behavioral state, tightly coupled to arousal32–35.”

    From Place and behavioral modulation of hippocampal neurons during immobility (2026) · cites this paper as [32]

    The Introduction says locomotion and arousal are often linked, supporting an association. But it also says they can be separately controlled, and the Results report increased arousal without locomotion. The paper does not characterize locomotion as a homogeneous behavioral state, and 'tightly coupled' omits the paper's qualification. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • The onset of locomotion, as well as vestibular activation, are correlated with pupil dilations and brain state transitions.

    “Indeed, the onset of locomotion, as well as vestibular activation, are correlated with pupil dilations and brain state transitions32,34,36.”

    From Place and behavioral modulation of hippocampal neurons during immobility (2026) · cites this paper as [32]

    The Results section ('NI NMB neurons encode locomotion, arousal, and theta rhythms'; page unavailable) links locomotion with pupil-measured arousal and hippocampal theta activity, supporting the locomotion portion of the claim. The copy does not address vestibular activation or show that it correlates with pupil dilation and brain-state transitions (searched: 'vestibular'). (LLM, conf=0.87)

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.
