Apprentissage d'un labyrinthe en y chez deux souches de souris. effets de la privation instrumentale et pharmacologique du sommeil
Abstract
Effects of instrumental and pharmacological deprivation of sleep on Y-maze learning have been studied in two inbred strains of mice (C57BR/cd/Orl and C57BL/6/Orl), having identical sleep rhythms, but mainly differing in their ability to learn. Administration of alpha-methyl-DOPA (100 mg/kg) provokes complete suppression of paradoxical sleep (PS) for 9-11 h. Injection immediately after each training session over the first 5 days caused a delay in acquisition of an active avoidance task in C57BR mice. Treated C57BL/6 mice exhibited a significant facilitation of acquisition. Similar results were obtained by instrumental deprivation of sleep for 10 h.

Long-term memory for simpler tasks, like one-way active avoidance and simple mazes, were less consistently affected by REM sleep deprivation.
“In contrast, long-term memory for simpler tasks, like one-way active avoidance and simple mazes, were less consistently affected (15, 249, 386, 390, 495, 558, 611, 644, 821, 872, 902, 907-909, 1072, 1091, 1334).”

Deprivation of REM sleep appeared to primarily impair memory formation on complex tasks, like two-way shuttle box avoidance and complex mazes, which encompass a change in the animals regular repertoire.
“Deprivation of REM sleep (mostly without simultaneous sleep recording) appeared to primarily impair memory formation on complex tasks, like two-way shuttle box avoid-ance and complex mazes, which encompass a change in the animals regular repertoire (69, 100, 312, 516, 525, 539, 644, 710, 713, 714, 787, 900, 903-906, 992, 1021, 1072, 1111, 1113, 1238, 1352, 1353).”

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.
