Paradoxical sleep increases predict successful learning in a complex operant task.
Abstract
The sleep of 16 Sprague-Dawley rats was continuously monitored both before and during task acquisition. Eight rats were exposed in turn to autoshaping, 10-response fixed-ratio (FR 10), and sequential operant (SO) tasks. They all learned the autoshaping and FR 10 tasks with equal ease. However, 4 rats were unable to solve the SO task and were labeled as slow learning (SL). The other 4 rats did learn the task and were labeled as fast learning (FL). FL rats exhibited more paradoxical sleep than either the SL group or the two control groups. The results suggest a subtle, but as yet unknown, biological difference between FL and SL rats within the Sprague-Dawley strain.

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.
