Identification of a rapid eye movement sleep window for learning of the win-shift radial arm maze task for male Sprague-Dawley rats: Sleep duration and psychiatric disorders
Abstract
This study identified a rapid eye movement sleep window (RSW) for the eight-arm win-shift radial arm maze (RAM) task. The RSW is defined as a period of time after training during which rapid eye movement (REM) sleep is necessary for efficient learning of a task. Rats were trained over a 15-day period on the win-shift RAM task. After daily training, groups of rats were deprived of REM sleep using the flowerpot technique or were returned to their cages to serve as controls. Groups were deprived of REM sleep during separate 4-h intervals, such that the entire 24-h time-period after training was investigated for the effects of REM sleep deprivation on learning. The results of the analyses of variance that were calculated for latency to completion data and a measure of the rate of performance improvements, and a survival analysis that was calculated using the first day of maze completion as a censoring variable, indicated that the RSW for the win-shift task is 0-4 h post-training.

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.
