Memory consolidation in human sleep depends on inhibition of glucocorticoid release

Plihal, Werner, Born, Jan·1999·NeuroReport

Abstract

Early sleep dominated by slow-wave sleep has been found to be particularly relevant for declarative memory formation via hippocampo-neocortical networks. Concurrently, early nocturnal sleep is characterized by an inhibition of glucocorticoid release from the adrenals. Here, we show in healthy humans that this inhibition serves to support declarative memory consolidation during sleep. Elevating plasma glucocorticoid concentration during early sleep by administration of cortisol impaired consolidation of paired associate words, but not of non-declarative memory of visuomotor skills. Since glucocorticoid concentration was enhanced only during retention sleep, but not during acquisition or retrieval, a specific effect on the consolidation process is indicated. Blocking mineralocorticoid receptors by canrenoate did not affect memory, suggesting inactivation of glucocorticoid receptors to be the essential prerequisite for memory consolidation during early sleep.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Increasing glucocorticoid levels during sleep by cortisol or dexamethasone impaired consolidation of memory for word pairs and temporal order in stories.

    “Accordingly, increasing glucocorticoid levels during sleep by postlearning administration of cortisol or dexamethasone impaired consolidation of memory for word pairs and for the temporal order in stories (932, 933, 1323).”

    From About Sleep's Role in Memory (2013) · cites this paper as [932]

  • Hippocampus-dependent declarative memory is impaired by the infusion of a low dose of cortisol during a period of early SWS-rich sleep.

    “hippocampus-dependent declarative memory has been impaired by the infusion of a low dose of cortisol during a period of early SWS-rich sleep [54].”
  • Inhibition of cortisol secretion and inactivation of glucocorticoid receptors appear to be critical for hippocampus-mediated formation of declarative memories.

    “Thus, inhibition of cortisol secretion and in particular inactivation of GRs appear to be critical for hippocampus-mediated formation of declarative memories.”

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.
