Paradoxical sleep deprivation applied two days after end of training retards learning
Abstract
Sprague-Dawley rats (N = 98) were trained in a 2-way shuttle shock avoidance task (50 trials/day for two consecutive days) and then subjected to a paradoxical sleep deprivation (PSD) regime beginning at least 24 hours after the last training session. Results from the various PSD groups indicated that a vulnerable PS window exists from 48-72 hours after the end of the last training session. PSD during this time period produced severe retention deficits. These results suggest the existence of a very long term posttraining PS involvement in the learning/memory process.

Selective deprivation of REM sleep during, but not outside of, identified PSWs impaired memory.
“Indeed, selective deprivation of REM sleep during, but not outside of, identified PSWs impaired memory (719,1101,1105,1106,1113,1115).”

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.
