Performance on a visual discrimination task shows longterm improvement after a single training session. When tested within 24 hr of training, improvement, was not observed unless subjects obtained at least 6 hr of postraining sleep prior to retesting, in which case improvement was proportional to the amount of sleep in excess of 6 hr. For subjects averaging 8 hr of sleep, overnight improvement was proportional to the amount of slow wave sleep (SWS) in the first quarter of the night, as well as… 

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.

Alpha Activity during Rem Sleep Contributes to Overnight Improvement in Performance on a Visual Discrimination Task

It is suggested that cortical activity during REM sleep contributed to procedural memory consolidation and the importance of measuring quantitative REM sleep components to elucidate the role of physiological sleep on memory consolidation in humans is highlighted.

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.

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.

A Role for Non-Rapid-Eye-Movement Sleep Homeostasis in Perceptual Learning

It is concluded that SWA is an important determinant of sleep-dependent gains in perceptual performance, a finding that directly implicates processes of sleep homeostasis in learning.

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

Contribution of night and day sleep vs. simple passage of time to the consolidation of motor sequence and visuomotor adaptation learning

It is suggested that “off-line” performance gains reflecting consolidation processes in the FTSL task benefit from sleep, even a short nap, while the simple passage of time is as effective as time in sleep for consolidation of VMA to occur.

Sleep-independent off-line enhancement and time of the day effects in three forms of skill learning

Results showed no sleep-related off-line improvement throughout the three tasks in a two-session re-learning design, but a sleep-independent time-based effect was found on the SRT task.



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.

The sequential hypothesis of the function of sleep

The time course of learning a visual skill

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.

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.

Reactivation of hippocampal ensemble memories during sleep.

Recordings from large ensembles of hippocampal "place cells" in three rats showed that cells that fired together when the animal occupied particular locations in the environment exhibited an increased tendency to fire together during subsequent sleep, in comparison to sleep episodes preceding the behavioral tasks.

Cue-sampling and goal-approach correlates of hippocampal unit activity in rats performing an odor-discrimination task

A functional organization of the hippocampus in which different cell types play complementary roles is suggested, including Cue-sampling cells activated by discriminative stimuli during attentive fixations may be involved in comparing relative cue valence, and theta cells may provide synchronization of sensory acquisition during sampling, as well as in orientation movements during approach.

The findings suggest that neuronal activity of hippocampal place cells in the awake states may influence the firing characteristics of these cells in subsequent sleep episodes, and increased firing rates along with the greater number of multiple spike bursts and the shorter interspike intervals within the burst, following exposure to a cell's place field, may represent possible information processing during sleep.

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.
