TL;DR
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.

1,127 Citations1991Avi Karni, Dov Sagi
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.
NatureModulation of visual cortical plasticity by acetylcholine and noradrenaline
865 Citations1986Mark F. Bear, Wolf Singer
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.

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.
NeuroscienceOf dreaming and wakefulness

It is argued that consciousness is fundamentally a closed-loop property, in which the ability of cells to be intrinsically active plays a central role, and the importance of spatial and temporal mapping in the elaboration of cognitive and perceptual constructs is discussed.

This hypothesis is given support by the demonstration that it is possible to synthesize, from a small number of examples of a given task, a simple network that attains the required performance level.
Vision ResearchDirection-specific improvement in motion discrimination
523 Citations1987Karlene Ball, Robert Sekuler
In all likelihood, most of the improvement in direction discrimination represents a change in visual function, rather than changes in nonsensory processes.

506 Citations1993Merav Ahissar, Shaul Hochstein
It is found that practicing one task did not improve performance in an alternative task, even though both tasks used exactly the same visual stimuli but depended on different stimulus attributes, suggesting that specific high-level attentional mechanisms, controlling changes at early visual processing levels, are essential in perceptual learning.

The rate of liberation of free acetylcholine from the surface of prostigmin-treated cerebral cortex in the freely moving cat has been determined in states of slow wave sleep, paradoxical or activated sleep, and waking.

394 Citations1992Ling-Po Shiu, Harold Pashler
The ability of human observers to discriminate the orientation of a pair of straight lines differing by 3° improved with practice, however, orientation discrimination did not improve when observers attended to brightness rather than orientation of the lines, suggesting that cognitive set affects tuning in retinally local orientation channels.

It is concluded that the data best support the idea of special periods of paradoxical sleep within the 24 hour period which are specifically involved with the learning process.
Vision ResearchLearning in grating waveform discrimination: Specificity for orientation and spatial frequency
271 Citations1981Adriana Fiorentini, Nicoletta Berardi
When the gratings are set perpendicular to those used for the training sessions, or their spatial frequency is changed by 1 octave, the effects of previous perceptual learning are lost, while transfer of learning effects is obtained for smaller changes in orientation (±30°) or spatial frequency (±12 octave).
Behavioral BiologyParadoxical sleep and memory storage processes
237 Citations1977William Fishbein, Baruch M. Gutwein
The accumulated data suggest that the events occurring during the paradoxical sleep phase play an integral part in memory storage processes in two ways: provide conditions which facilitate the conversion of a learned response into a stable long-term memory, and actively maintain the stability of a consolidated memory trace.

The results suggest that, at least for humans, REM sleep does not facilitate memory consolidation and that stage 4 sleep may be beneficial to memory.

It is demonstrated that the unilateral removal of a digit in cats, followed by stimulation of an adjacent digit, produces a pattern of metabolic activity in the somatosensory cortex that is dramatically expanded when compared with the opposite (normal) hemisphere.

159 Citations1970Jacob Empson, P. R. F. Clarke
This work has suggested that rapid eye movement (REM) sleep is a non-specific indication of many forms of synthesis within cerebral neurones, and that periods of massive learning would cause high percentages of REM sleep.
Physiology & BehaviorParadoxical sleep at selective times following training is necessary for learning
125 Citations1982Christopher Smith, Stephen Butler
It was found that only PSD applied between 9-12 hours or 17-20 hours after the daily training sessions resulted in acquisition deficits, and any other equivalent length PSD regime which overlapped with either of the time "windows" resulted in severe retardation of task acquisition.
Biological PsychologyREM sleep and memory consolidation

It was found that recall accuracy following REM deprivation was significantly poorer than following S4 deprivation, and the degree of deterioration in recall accuracy during REM recovery sleep was less than during S4 recovery sleep.

114 Citations1984James A. Horne, Michael J. McGrath
There are several shortcomings with the methodology of animal RSD investigations, and RSD seems to produce arousal and stereotyped behaviour which may interfere with learning etc., and consequently give artificial support to the hypothesis, which is not rejected.
