The function of dream sleep

Crick, Francis, Mitchison, Graeme·1983·Nature

Abstract

We propose that the function of dream sleep (more properly rapid-eye movement or REM sleep) is to remove certain undesirable modes of interaction in networks of cells in the cerebral cortex. We postulate that this is done in REM sleep by a reverse learning mechanism (see also p. 158), so that the trace in the brain of the unconscious dream is weakened, rather than strengthened, by the dream.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Francis Crick and Graeme Mitchinson proposed in 1983 an alternative purpose for dreams called 'reverse learning,' in which dreaming removes undesirable connections and helps the brain unlearn.

    “Notably, Francis Crick and Graeme Mitchinson proposed an alternative purpose for dreams in 1983, which they called “reverse learning.”82,83 In this hypothesis, the point of dreaming is somehow to remove “undesirable” connections and help the brain “unlearn.””
  • The findings speak against the view posed by Crick and Mitchison.

    “Overall, these findings speak against the view posed by Crick and Mitchison (236).”

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.
