Evidence for a paradoxical sleep window for place learning in the Morris water maze

Smith, Carlyle, Rose, Gregory M.·1996·Physiology & Behavior

Abstract

Sprague-Dawley rats were given 4 consecutive days of training in the hidden platform version of the Morris water maze. They were then given paradoxical sleep deprivation (PSD) for 12 h either immediately after each training session or after a 12-h delay. The former group showed impaired learning on the second day of training compared to the 12-h-delayed PSD group or a nondeprived control group. In a second experiment, three groups of rats were trained as before and then given PSD for a 4-h interval beginning either immediately after, 4 h after, or 8 h after the end of each training session. Only rats exposed to PSD during the period beginning 4 h after the end of training each day showed an acquisition deficit. In a third experiment, rats were trained in a visible platform version of the water maze and exposed to PSD for a 12-h period either beginning immediately after the last training trial each day or after a 12-h rest delay. Neither of these groups was impaired on the task compared to a non-PSD control group. These results suggest that there is a PS window for place, but not cue, learning in the Morris water maze.

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?

  • 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.
