Memory consolidation in developmental disorders
<p>The relationship between memory and adaptive functioning was studied in sample of 268 children with attention deficit/hyperactivity disorder (ADHD, n = 83), autism spectrum disorder (ASD, n = 62), velo-cardio-facial syndrome (VCFS, n = 21), and low birth weight (LBW, n = 38) and neurotypicals (n …

Learning new words: effects of meaning, memory consolidation, and sleep
… of novel word meanings benefit from offline memory consolidation? Experiments 4-7 suggested that this is the case. Experiment 4 showed that consolidated novel words elicited faster semantic decisions than words learned just before testing, while Experiment 5 showed that cued recall of word …

Optogenetic dissection of the dopaminergic circuitry involved in memory consolidation
… tagging-and-capture’ (STC) theory of cellular memory consolidation holds that memory persistence can be altered by prior or subsequent patterns of neural activity (Redondo & Morris 2011). The aim of this thesis was to develop a realistic model of everyday memory for mice and use the optogenetic …

The Relationship Between Affect in Dreams and Emotional Memory Consolidation
… in various neurocognitive processes such as memory consolidation, however, an area that has not been fully researched is the role of dreaming in these memory processes. This study aimed to determine the relationship between affect experienced in dreams and emotional memory consolidation. …

PPARγ-pERK interaction restores memory consolidation in an Alzheimer’s disease model
… MAPK) is required for many forms of learning and memory that are affected in AD, and since both PPARγ and ERK are key mediators of insulin signaling, we tested the hypothesis that RSG-mediated cognitive improvement induces a hippocampal PPARγ pattern of gene and protein expression that converges …

Sequential Transcriptional Gates in The Thalamo-Cortical Circuit Coordinate Memory Consolidation
… circuit that may be responsible for extending memory time-scales. I began by developing a virtual reality-based behavioral paradigm where, by varying the frequency of learned associations, mice formed multiple memories but only consolidated some, while forgetting others, over the span of weeks. …

Learning to read: Effects of memory consolidation on orthographic and lexical learning
In recent years the role of offline consolidation in supporting word learning has attracted great interest and has provided valuable insight into how novel spoken and written words are learned. Relatively little attention has focused on whether offline consolidation supports the learning and …

The Effects of Self-Guided Meditation and Napping on Memory Consolidation in Humans
… sleep (overnight or daytime naps) benefits memory consolidation (Diekelmann & Born, 2010; Mednick, Nakayama, & Stickgold, 2003; Plihal & Born, 1999; Walker et al., 2003). However, most investigations have employed various forms of “active wakefulness” (e.g., sensorimotor and cognitive tasks) …

The Influence of Aging and Parkinson’s Disease on Neural Oscillations Associated with Memory Consolidation
… this coupling is fundamental to the process of memory consolidation. Specifically, high-frequency oscillations, or ripples, in the hippocampal formation are required for the conversion of short-term to long-term memory. These ripples couple to two slower oscillations found in the cortex, delta …

A role for the SHANK1 scaffold protein in experience-induced synaptic plasticity and memory consolidation
… and during learning as a likely process for memory consolidation. During early postnatal development, dendritic spine density increases in numerous sensory cortices, reaching a peak in adolescence, followed by a subsequent reduction in dendritic spine density to adult levels. In the …

Genetic and behavioral discrimination of dopamine 1 and 5 receptors in hippocampal dependent memory consolidation
… and drug addiction. The role of DA in working memory and procedural learning is also well established. DA is a ubiquitous neurotransmitter that affects much of the brain, but very little is known how dopamine functions in hippocampal dependent learning. It was only until recently that …

Effects of augmentation agents on emotional memory consolidation and subliminal cue exposure to fear-relavent stimuli
… mechanisms of action of cognitive enhancers in memory consolidation and extinction learning. Study 1 examined the effect of DCS and cortisone, another cognitive enhancer, on emotional memory consolidation in a nonclinical sample to investigate the effect of these augmentation agents on emotional …

The relationship between elevated night-time Glucocorticoid activity and dreaming: a perspective on sleep-dependent memory consolidation
Background. The consolidation of episodic memory is particularly vulnerable to fluctuations in glucocorticoid levels, both during wakefulness and during sleep. Corticosteroid exposure is associated with changes in endogenous glucocorticoid activity, sleep disruption, episodic memory impairment, and …

NREM sleep spindles and slow wave sleep in younger and elderly women: an investigation of their influence on declarative memory consolidation
… spindles play an essential role in declarative memory consolidation. However, this role is not well understood in the ageing women. With advancing age, SWS and sleep spindles undergo significant decreases in duration and density, while there is a simultaneous decline in declarative memory. The …

The Role of Sleep in Memory Consolidation with an Induced Sleep-Like State in Drosophila AND The Role of Alpha-synuclein in Fatty Acid Metabolism
<p>The Role of Sleep in Memory Consolidation with an Induced Sleep-like State in Drosophila</p><p>Introduction: Sleep plays an important role in memory consolidation. However, the underlying mechanism remains elusive. The importance of sleep in the memory consolidation process has been demonstrated …

The relationship between sleep and memory in PTSD
… to the formation of memories. Successful memory consolidation during sleep is contingent on the presence of slowwave sleep (SWS), REM sleep and the successful transition of stages across the night. In PTSD, both sleep and memory processes are disrupted, but no previous study has examined …

Understanding the Relationship Between Working Memory and Long-Term Memory
… concerns the relationship between working memory and long-term memory. Recent research has investigated how the processing that occurs while information is held in working memory influences successful long-term memory creation. Both working memory consolidation and maintenance have been …

Protein Synthesis Inhibitors Impair Memory by Disrupting Release of Neurotransmitters Important for Memory Modulation
… that de novo protein synthesis is necessary for memory consolidation is widely accepted, yet supported by evidence based primarily on results using protein synthesis inhibitors. Injection of a protein synthesis inhibitor near the time of training often spares memory of the training experience for …
