Odor Cues During Slow-Wave Sleep Prompt Declarative Memory Consolidation
TLDR
It is shown that reactivation indeed causes memory consolidation during sleep, and functional magnetic resonance imaging revealed significant hippocampal activation in response to odor re-exposure during SWS.
Learning-Dependent Increases in Sleep Spindle Density
TLDR
Results indicate that spindle activity during non-REM sleep is sensitive to previous learning experience, and spindle density was correlated to recall performance both before and after sleep.
Hemodynamic cerebral correlates of sleep spindles during human non-rapid eye movement sleep
TLDR
The recruitment of partially segregated cortical networks for slow and fast spindles further supports the existence of two spindle types during human non-rapid eye movement sleep, with potentially different functional significance.
Grouping of Spindle Activity during Slow Oscillations in Human Non-Rapid Eye Movement Sleep
TLDR
These results provide the first evidence in humans of grouping of spindle and beta activity duringslow oscillations and support the concept that phases of cortical depolarization during slow oscillations, reflected by surface-positive (depth-negative) field potentials, drive the thalamocortical spindle activity.
Emotional memory formation is enhanced across sleep intervals with high amounts of rapid eye movement sleep.
TLDR
Results are consonant with a supportive function of REM sleep predominating late sleep for the formation of emotional memory in humans, and particularly enhanced memory for emotional texts.
Sleep to Remember
TLDR
A central role for consolidating memories is played by the slow oscillation, that is, the oscillating field potential change dominating SWS, which synchronizes the occurrence of sharp wave ripples accompanying memory reactivations in the hippocampus with thalamocortical spindle activity.
Early sleep triggers memory for early visual discrimination skills
TLDR
It is suggested that procedural memory formation is prompted by slow-wave sleep-related processes, only after periods of early sleep have occurred and late REM sleep may promote memory formation at a second stage.
Declarative memory consolidation: mechanisms acting during human sleep.
TLDR
It is shown that declarative memory benefits mainly from sleep periods dominated by SWS, whereas there is no consistent benefit of this memory from periods rich in rapid eye movement (REM) sleep.
The influence of learning on sleep slow oscillations and associated spindles and ripples in humans and rats
TLDR
This work examined whether slow oscillations also group learning‐induced increases in spindle and ripple activity, thereby providing time‐frames of facilitated hippocampus‐to‐neocortical information transfer underlying the conversion of temporary into long‐term memories.
Sleep after learning aids memory recall.
TLDR
It is shown that declarative memory is enhanced when sleep follows within a few hours of learning, independent of time of day, and with equal amounts of interference during retention intervals.
