Recall of paired-associate lists (declarative memory) and mirror-tracing skills (procedural memory) was assessed after retention intervals defined over early and late nocturnal sleep. In addition, effects of sleep on recall were compared with those of early and late retention intervals filled with wakefulness. Twenty healthy men served as subjects. Saliva cortisol concentrations were determined before and after the retention intervals to determine pituitary-adrenal secretory activity. Sleep was… 

Emotional memory formation is enhanced across sleep intervals with high amounts of rapid eye movement sleep.

Results are consonant with a supportive function of REM sleep predominating late sleep for the formation of emotional memory in humans, and particularly enhanced memory for emotional texts.

Memory consolidation during sleep: Interactive effects of sleep stages and HPA regulation

It is shown that the different sleep stages and the concomitant glucocorticoid release are interactively involved in the consolidation of different types of memories and the importance of pituitary–adrenal inhibition during early SWS-rich sleep for efficient consolidation of declarative memory.

Midlife decline in declarative memory consolidation is correlated with a decline in slow wave sleep.

A decline in sleep-associated declarative memory consolidation that develops already during midlife and is associated with a decrease in early nocturnal SWS is indicated.

The effects of sleep on episodic memory in older and younger adults

Amount of time spent sleeping correlated highly with sleep benefit in older adults, suggesting that quantity of total sleep, and/or time spent in some stages of sleep, are important contributors to age-related differences in memory consolidation or protection from interference during sleep.

Moderate OSA is associated with a significant impairment of procedural and verbal declarative memory, and future work is needed to further determine the contribution of structural or functional alterations in brain circuits relevant for memory.

It was suggested that the memory loss after sleep was at least in part due to a failure of rehearsal and recoding at the time of learning.

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.

Corticotropin-releasing hormone-induced adrenocorticotropin and cortisol secretion depends on sleep and wakefulness.

An inhibiting influence of sleep is demonstrated on stimulated ACTH and cortisol secretion during early nocturnal sleep, with this effect restricted to the early part of sleep.

Paradoxical sleep and memory storage processes.

Sleep and Memory

There appears to be a period of consolidation before a memory becomes permanently stored, and lesions of hippocampal formation lead to memory deficits for up to 6 weeks following learning in monkeys, and more than a year in man.

Cortisol secretion is inhibited during sleep in normal man.

The inhibitory effect of the behavioral complex of sleeping on cortisol secretion superimposed on its endogenous circadian and ultradian rhythm is demonstrated and may be used to entrain and time the period and phase of biological rhythms in relation to shift work, sleep deprivation, and transmeridian jet travel.

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.
