Improvement after practicing visual texture discrimination does not occur until several hours after practice has ended. We show that this improvement strongly depends on sleep. To specify the process responsible for sleep-related improvement, we compared the effects of 'early' and 'late' sleep, dominated respectively by slow-wave and rapid eye movement (REM) sleep. Discrimination skills significantly improved over early sleep, improved even more over a whole night's sleep, but did not improve… 

Sleep forms memory for finger skills

The effect of sleep after learning proved to be stable when retesting was postponed for another night, to exclude effects of sleep loss and to assure that all subjects had sufficient sleep before retrieval testing.

The functional anatomy of sleep-dependent visual skill learning.

Learning of procedural skills develops gradually, with performance improving significantly with practice. But improvement on some tasks, including a visual texture discrimination task, continues in

Sleep-dependent learning: a nap is as good as a night

It is reported that sleep-dependent learning of a texture discrimination task can be accomplished in humans by brief naps containing both slow-wave sleep (SWS) and rapid eye movement (REM) sleep.

Posttraining Sleep Enhances Automaticity in Perceptual Discrimination

In this auditory learning paradigm, posttraining sleep appears to reduce the voluntary attentional effort required for successful perceptual discrimination by facilitating the intrusion of a potentially meaningful stimulus into one's focus of attention for further evaluation.

Sleep after learning aids memory recall.

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.

Motor Memory Consolidation in Sleep Shapes More Effective Neuronal Representations

It is shown that storing a motor skill during sleep reorganizes its brain representation toward enhanced efficacy, and this latent consolidation during sleep changes the brain representation of the motor skill by reducing overall the neocortical contributions to the representation.

Interocular transfer of perceptual skills after sleep.

It is reported that besides consolidation, sleep also generalizes the learned perceptual abilities to the untrained eye and quadrant, suggesting that sleep-dependent perceptual skills continue developing at a later visual-process stage than the V1 area, where learning is not monocular anymore.



Dependence on REM sleep of overnight improvement of a perceptual skill.

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.

Sleep states and memory processes

Effects of Early and Late Nocturnal Sleep on Declarative and Procedural Memory

The experiments for the first time dissociate specific effects of early and late sleep on two principal types of memory, declarative and procedural, in humans, and the benefit from sleep on recall depended on the phase of sleep and on the type of memory.

Effects of early and late nocturnal sleep on priming and spatial memory.

It appears that earlySleep dominated by SWS facilitates consolidation of declarative memory whereas late sleep dominated by REM sleep facilitates consolidationof nondeclarativeMemory.

Dexamethasone blocks sleep induced improvement of declarative memory

Visual Discrimination Task Improvement: A Multi-Step Process Occurring During Sleep

The results suggest that, in the case of this visual discrimination task, both SWS and REM are required to consolidate experience-dependent neuronal changes into a form that supports improved task performance.

Sleep states, memory processes and synaptic plasticity

Memory consolidation in human sleep depends on inhibition of glucocorticoid release.

It is shown in healthy humans that an inhibition of glucocorticoid release from the adrenals serves to support declarative memory consolidation during sleep, and blocking mineralocortioid receptors by canrenoate did not affect memory, suggesting inactivation of glucOCorticoids receptors to be the essential prerequisite for memory consolidationduring early sleep.

Sleep, Dreams and memory: an overview

SUMMARY  Investigations into the role played by sleep in information processing have consistently shown that the retention of information is better when the memory storage is followed by a period of
