Performance of a basic visual discrimination task improved after a normal night's sleep, indicating that a process of human memory consolidation, active during sleep, is strongly dependent on REM sleep.
Abstract
Several paradigms of perceptual learning suggest that practice can trigger long-term, experience-dependent changes in the adult visual system of humans. As shown here, performance of a basic visual discrimination task improved after a normal night's sleep. Selective disruption of rapid eye movement (REM) sleep resulted in no performance gain during a comparable sleep interval, although non-REM slow-wave sleep disruption did not affect improvement. On the other hand, deprivation of REM sleep had no detrimental effects on the performance of a similar, but previously learned, task. These results indicate that a process of human memory consolidation, active during sleep, is strongly dependent on REM sleep.

About sleep's role in memory

TL;DR: This review aims to comprehensively cover the field of "sleep and memory" research by providing a historical perspective on concepts and a discussion of more recent key findings.

Sleep function and synaptic homeostasis.

TL;DR: This paper reviews a novel hypothesis about the functions of slow wave sleep-the synaptic homeostasis hypothesis, which accounts for a large number of experimental facts, makes several specific predictions, and has implications for both sleep and mood disorders.

Affect and Creativity at Work

TL;DR: In this article, the authors explored how affect relates to creativity at work using both quantitative and qualitative longitudinal data from the daily diaries of 222 employees in seven companies, and examined the nature, form, and temporal dynamics of the affect-creativity relationship.

Local sleep and learning

TL;DR: It is shown that sleep homeostasis indeed has a local component, which can be triggered by a learning task involving specific brain regions, and that the local increase in SWA after learning correlates with improved performance of the task after sleep.
Journal ArticleDOI

Sleep-dependent memory consolidation

TL;DR: Converging evidence, from the molecular to the phenomenological, leaves little doubt that offline memory reprocessing during sleep is an important component of how the authors' memories are formed and ultimately shaped.

Where practice makes perfect in texture discrimination: evidence for primary visual cortex plasticity

TL;DR: This work reports remarkable long-term learning in a simple texture discrimination task where learning is specific for retinal input and suggests that learning involves experience-dependent changes at a level of the visual system where monocularity and the retinotopic organization of thevisual input are still retained and where different orientations are processed separately.

Modulation of visual cortical plasticity by acetylcholine and noradrenaline

TL;DR: The results suggest that intracortical 6-OHDA disrupts plasticity by interfering with both cholinergic and noradrenergic transmission and raise the possibility that ACh and NA facilitate synaptic modifications in the striate cortex by a common molecular mechanism.

The time course of learning a visual skill

TL;DR: Here it is conjecture that some types of perceptual experience trigger permanent neural changes in early processing stages of the adult visual system, which may take many hours to become functional.
