TLDR
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.read more

Sleep function and synaptic homeostasis.
Giulio Tononi,Chiara Cirelli +1 more
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.
Journal ArticleDOI
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
Avi Karni,Dov Sagi +1 more
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.

TL;DR: Probably applications of this new understanding of the neural bases of learning and memory range from education to the treatment of learning disabilities to the design of new artificial intelligence systems.

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
Avi Karni,Dov Sagi +1 more
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.
