MemTable : contextual memory in group workspaces
… both digital and physical interactions in its memory. The goal of the project is to demonstrate hardware and software design principles that integrate recording, recalling, and reflection during the life cycle of a project in one tabletop system. MemTable's hardware design prioritizes …

Behavioural and Neuronal Correlates of Long-term Contextual Memory for Cocaine: Relevance to Craving and Relapse
… memories for drug experience and associated contextual cues can provoke craving and resumption of drug use, particularly when a reminder of a highly charged context is encountered. In this thesis, three key questions related to the maintenance of long-term memory for drug-associated contexts …

The role of neurogranin in modulating contextual memory and plasticity : FMRP involvement and adrenergic-dependent facilitation
… that protein synthesis is essential for both memory formation and the long-lasting changes in synaptic strength that accompany learning. However, it's still unclear when protein synthesis needs to occur relative to the experience to form durable memories, and the identities and roles of …

Molecular mechanisms of memory formation : using activity regulated genes to identify active neural circuits
… and cellular processes underlying learning and memory. We have previously reported that the activity-regulated transcription factor Npas4 is selectively induced in a sparse population of CA3 following contextual fear conditioning. Global knockout or selective deletion of Npas4 in CA3 both …

An Electrophysiological Investigation of Source Memory Development in Early Childhood
The present study examined source memory development in a sample of 4 and 6 year children. Patterns of brain electrical (EEG) activity were examined in order to provide a neural basis for the role of prefrontal cortex functioning during source monitoring. Children were taught a series of novel …

Soundfield representation, reconstruction and perception
… adaption, sensory bias, sensory conflict, and contextual memory cannot be ignored. If the listening environment is inappropriate or in conflict with the desired perceptual experience, little is gained from more complex soundfield representation or reconstruction. The imp! lications of this …

Source Memory Failures: Comparing Source Misattribution to Sources of False Memories
… demonstrates incorrect binding of a memory with its contextual information. By contrast, false memories are memories of events that did not occur. Although theoretically they should not be bound with contextual information, often, false memories are accompanied by contextual …

Illuminating the mental memoriam
… with historical studies that lead to the modem memory engram theory. Then, I present our recent advances in memory research that combine transgenic and optogenetic approaches to reveal underlying neuronal substrates sufficient for activating mnemonic processes. Our studies' conclusions are …

The Impact of Emotion on Associative Memory
The effect of emotion on associative memory remains unclear. Inconsistent findings in the literature are leading to theories with opposite predictions. Obtaining a clearer view of the impact of emotion on associative memory remains of crucial importance, particularly as it could shed light on the …

Long-Term Memory Biases Auditory Spatial Attention: Healthy and Impaired “Memory-Guided Attention”
Attention and memory may be impaired in individuals at-risk for Alzheimer’s disease (AD), though standard cognitive assessments typically study the two in parallel. In reality, attention and memory interact to facilitate processing, and thus a more integrative approach is required. Here, I used a …

Neuropsychological Correlates of Anosognosia in MCI and Dementia
… for general cognitive ability and delayed contextual memory being the most predictive of all the measures administered. Thus, the current study provides evidence for the utility of routine assessment of anosognosia in MCI and dementia neuropsychological evaluation.

A novel developmental rodent model to investigate the neural basis of episodic memory
Episodic memory is the recollection of unique autobiographical events, including rich detail of times, places and associated contextual information. In neurodegenerative diseases, such as Alzheimer’s disease, episodic memory is greatly impaired. The ability to recall episodic memories is thought to …

Non-proteolytic roles of the ubiquitin-proteasome system in memory formation across the lifespan
Memory formation and decline are driven by complex molecular mechanisms and region-specific changes in the brain. Epigenetic modifications, such as histone monoubiquitination and ubiquitin signaling, have emerged as key players in these processes. While monoubiquitination of histone H2B is a …

Organization of spatiotemporal information and relational memory in the hippocampus
… the role of the hippocampus and relational memory in organizing episodic memory during navigation and reconstruction. Navigation is a critical component in most organisms’ survival. Reconstruction, on the other hand, provides an incredibly rich method of evaluating the precise information …

Assessing the role of the hippocampus in amygdala kindled fear : an analysis of environmental habituation
… As the hippocampus plays an integral role in contextual learning, the ability of the animals to habituate to a novel environment was evaluated, in order to determine if the rats displayed impairments in this hippocampal-dependent function. In Experiment 1, long-term kindled rats demonstrated …

Ontogeny of contextual fear conditioning: behavioral, neuropharmacological and molecular mechanisms
… changes in developing rodents using a variant of contextual fear conditioning called the context preexposure facilitation effect (CPFE). The CPFE is a variant of contextual fear conditioning in which acquisition of the contextual representation (preexposure phase) and association of the retrieved …
