Multifractal Complexity of Hippocampal Memory Processing
… has long been associated with learning and memory occurring as reverberating activity patterns within ensembles of hippocampal neurons. Fractals, omnipresent in biological and physical systems, often manifest when systems are iterative or reverberatory, and consequently are detectable in …

Physiological mechanisms of hippocampal memory processing : experiments and applied adaptive filtering
… for the formation and storage of episodic memory, however, the computations within and between hippocampal subregions (CA1, CA3, and dentate gyrus) that mediate these memory processing functions are not completely understood. We investigate by recording in the hippocampal subregions as rats …

Successful cognitive aging: Implications of early Alzheimer's disease detection, lifestyle choices, and environmental factors
… particular emphasis has been given to the hippocampal memory system, given the impact aging and Alzheimer's disease has on the hippocampus. Turning to the empirical work, chapter two describes the use of a new memory task in young, healthy older, and very mild Alzheimer's disease …

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 …

EXAMINING THE INFLUENCE OF TIME AND REPETITION ON RECENT AND REMOTE AUTOBIOGRAPHICAL MEMORY RETRIEVAL USING fMRI
… tested the prediction made by MTT that hippocampal memory traces expand and strengthen as a function of repeated memory retrievals. An fMRI paradigm was used to compare the effect of memory retrieval versus the mere passage of time on hippocampal activation. Participants retrieved remote …

Cardiorespiratory fitness as a modulator of hippocampal subfield structure and function in cognitive aging
… a brain region that is critical for episodic memory formation and spatial navigation. Accurate episodic memory formation requires pattern separation, a neurocomputational process that orthogonalizes similar stimulus input into distinct neural representations and can be examined using …

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 …

Mechanisms of hippocampal relational memory binding
… about the mental representations that underlie memory for the complex compositions of people, places, things, and events that comprise everyday mnemonic experience, the mechanisms that bind, encode, and reconstruct these representations, and the mathematical frameworks that describe these …
