“…Another potential avenue for research lies in investigating whether recovery sleep can reduce false memory formation. Prior work suggests that sleep‐related consolidation may preferentially benefit weaker memories (Drosopoulos et al ., 2007), and can take place for several nights after encoding (Schonauer et al ., 2015). This could potentially reduce memory impairment in persons sleep‐deprived at encoding.…”

SummaryRetrieving false information can have serious consequences. Sleep is important for memory, but voluntary sleep curtailment is becoming more rampant. Here, the misinformation paradigm was used to investigate false memory formation after 1 night of total sleep deprivation in healthy young adults (N = 58, mean age ± SD = 22.10 ± 1.60 years; 29 males), and 7 nights of partial sleep deprivation (5 h sleep opportunity) in these young adults and healthy adolescents (N = 54, mean age ± SD = 16.67 ± 1.03 years; 25 males). In both age groups, sleep‐deprived individuals were more likely than well‐rested persons to incorporate misleading post‐event information into their responses during memory retrieval (P < 0.050). These findings reiterate the importance of adequate sleep in optimal cognitive functioning, reveal the vulnerability of adolescents' memory during sleep curtailment, and suggest the need to assess eyewitnesses' sleep history after encountering misleading information.

“…A possible link to sleep may be significant considering the mounting evidence for the importance of sleep to consolidation of declarative memories (e.g. Ellenbogen, Hulbert, Stickgold, Dinges & Thompson-Schill, 2006;Drosopoulos, Schulze, Fischer & Born, 2007). In addition, a clear association between waking and amnesic attacks in TEA has led Butler and Zeman (2008) to suggest the possibility that nocturnal subclinical epileptiform activity may be a causal factor in the memory deficits seen in this condition.…”

When “long-term memory” no longer means “forever”: Analysis of accelerated long-term forgetting in a patient with temporal lobe epilepsy

"long-term memory" no longer means "forever": analysis of accelerated long-term forgetting in a patient with temporal lobe epilepsy. ' Neuropsychologia 48 (6) [1707][1708][1709][1710][1711][1712][1713][1714][1715] Link to published version: A case study is presented of a patient, RY, with temporal lobe epilepsy, who exhibited such a profile of "accelerated long-term forgetting". To investigate the effect of recalling information on later retention, recall and recognition for pairs of novel stories were tested at five intervals ranging from 30 minutes to 4 weeks; we also manipulated whether or not recall and recognition were repeatedly tested for stories. Two studies are reported, one before RY commenced treatment with anticonvulsant medication, and one following 6 months of treatment. Very similar memory profiles were observed in both settings. Against a background of above average cognitive function, results showed that RY's free recall, although initially average or above, was significantly impaired at extended delays (within 24 hours) for non-repeatedly recalled episodic information. However, this contrasted with normal performance for information that had been repeatedly recalled. An unresolved issue in the field is the impact of anticonvulsant medication on alleviating long-term forgetting, and the current study shows that anticonvulsant medication can have negligible beneficial effects in improving the rate of long-term forgetting in this type of patient. In addition, our study highlights the possible protective effect of active review of recent episodic memories.

“…Furthermore, whereas most studies have entailed the learning of a single novel task, real-world learning often involves the acquisition of a variety of skills or information that may interfere with other learning acquired throughout the day. A number of recent studies have explored the interaction between interference and sleep consolidation (e.g., Walker et al 2003;Ellenbogen et al 2006Ellenbogen et al , 2009Korman et al 2007;Drosopoulos et al 2007;Diekelmann et al 2011;Alger et al 2012;Sheth et al 2012). Remarkably, the memory benefit of sleep is often greater in conditions with interference compared to conditions that only learn a single task.…”

How new experiences are solidified into long-lasting memories is a central question in the study of brain and behavior. One of the most intriguing discoveries in memory research is that brain activity during sleep helps to transform newly learned information and skills into robust memories. Though the first experimental work linking sleep and memory was conducted 90 years ago by Jenkins and Dallenbach, the case for sleep-dependent memory consolidation has only garnered strong support in the last decade. Recent studies in humans provide extensive behavioral, imaging, and polysomnographic data supporting sleep consolidation of a broad range of memory tasks. Likewise, studies in a few animal model systems have elucidated potential mechanisms contributing to sleep consolidation such as neural reactivation and synaptic homeostasis. Here, we present an overview of sleep-dependent memory consolidation, focusing on how investigations of sleep and learning in birds have complemented the progress made in mammalian systems by emphasizing a strong connection between behavior and physiology. We begin by describing the behavioral approach that has been utilized to demonstrate sleep consolidation in humans. We then address neural reactivation in the rodent hippocampal system as a putative mechanism of sleep consolidation. Next, we discuss the role of sleep in the learning and maintenance of song in zebra finches. We note that while both the rodent and zebra finch systems provide evidence for sleep-dependent memory changes in physiology and behavior, neither duplicates the pattern of changes most commonly observed in humans. Finally, we present a recently developed model of sleep consolidation involving auditory classification learning in European starlings , which has the potential to connect behavioral evidence of sleep consolidation as developed in humans with underlying neural mechanisms observable in animals.
