Abstract

The REM sleep is a paradoxical sleep state characterized by brain activity similar to wakefulness, rapid-eye-movement, and lack of muscle tone. REM sleep is a fundamental brain function as it is evolutionary conserved across species, including human, mouse, bird, and even reptiles. The physiological importance of REM sleep is highlighted by severe sleep disorders incurred by a failure in REM sleep regulation. Despite the intense interest in the mechanism of the REM sleep regulation, the molecular machinery is largely left to be investigated. In models of REM sleep regulation, acetylcholine has been a pivotal component. However, even newly emerged techniques such as pharmacogenetics and optogenetics, have not fully clarified the function of acetylcholine either at the cellular level or neural-circuit level. Recently, we discovered that the Gq type muscarinic acetylcholine receptor genes; Chrm1 and Chrm3, are essential for REM sleep. In this review, we attempt to develop a perspective of current knowledge on REM sleep from a molecular viewpoint. This attempt should be a starting point to clarify the molecular machinery underlying the REM sleep regulation and will provide molecular insights to explore physiological functions of REM sleep and its pathological roles in REM-sleep-related disorders such as depression, PTSD, and neurodegenerative diseases.

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

  • REM sleep is characterized by emergence of strong theta-band EEG activity and absence of most other frequency bands.

    “REM sleep is characterized by the emergence of strong theta-band EEG activity and the absence of most other frequency bands26 and is associated with processes of memory selection and storage27, which are proposed to be reflected as dreams.”

    From Energy paradox in REM sleep: balancing supply and consumption in brain metabolism (2026) · cites this paper as [26]

    The Introduction identifies theta oscillation as characteristic of REM sleep, and Future Perspective describes theta as dominant in the EEG during REM sleep (page numbers unavailable). Neither passage says that most other frequency bands are absent; dominance does not establish absence. (LLM, conf=0.85)

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.
