This thesis investigates the role of the hippocampus in object memory. Currently, the role of the hippocampus in object recognition is unclear, with some studies demonstrating a delay-dependent impairment after hippocampal damage, others showing no impairment. The present thesis used the novel object recognition task and its variants to investigate various types of object memory in hippocampal lesion rats. In the first study, impairments were observed in discriminating object order and associating objects with contexts, while no impairment was observed in novel object recognition. In the secon

Sutherland, Sparks and Lehmann (2010) proposed a new theory of memory consolidation, termed Distributed Reinstatement Theory (DRT), where the hippocampus (HPC) is needed for initial encoding but some types of memories are established in non-HPC systems through post-learning HPC activity. An evaluation of the current methodology of temporary inactivation was conducted experimentally. By permanently implanting two bilateral guide cannulae in the HPC and infusing ropivacaine cellular activity could be reduced by 97%. Rats were trained in a context-fear paradigm.

The most insidious consequences of transient ischemia are its effect on the hippocampus and the memory systems it serves. The novelty preference test is a direct measure of memory function and has been used in the rat and primate animal models. The gerbil animal model has been used extensively to study the mechanism of ischemic brain damage; however, the novelty preference paradigm has not been used to study memory impairment in this species. In addition, the novelty preference paradigm has not been tested with models of ischemia. In the present experiment, Mongolian gerbils were tested in two

There are numerous clinical and experimental accounts of retrograde and anterograde amnesia resulting from damage to the hippocampus (HPC). Several theories on the HPC hold that only certain types of recent memories should be affected by HPC damage. These theories do not accurately predict the circumstances within which memories are vulnerable to HPC damage. Here I show the HPC plays a role in the formation and storage of a wider range of memories than is posited in contemporary theories. I will demonstrate that an important factor in elciting retrograde amnesia is the number of similar learni

Biophysical simulations of memory must choose which aspects of known neurophysiology and neuroanatomy to model. Relevant aspects were constrained by functional requirements determined for on-line acquisition in context dependent memory, memory that is retrieved by contextual cues. In an on-line task, the protocol of data presentation and the tunes at which encoding or retrieval in memory is needed are not predetermined. A sequence of neuronal spike patterns representing items may be presented only once. Yet, episodic memory of the sequence immediately encodes the temporal context of fam

The present experiments were designed to examine the hypothesis that the hippocampus and caudate nucleus are parts of independent memory systems which differ in the type of memory they mediate.

Lesions of the fimbria-fornix produced the opposite behavioral dissociation. In experiment 2, lesions of the caudate nucleus produc

The hippocampus and non-hippocampal long-term memory systems each have the capacity to learn and express contextual fear memory. How these systems interact during learning and remembering revolves around hippocampal mediated interference, where the hippocampus dominates for both the acquisition and expression of long-term memory. Hippocampal interference during learning can be overcome by modifying learning parameters such that learning is distributed across multiple independent sessions. The standard view of the role of the hippocampus in long-term memory retrieval is that it is temporally li

Long-term potentiation (LTP) is an activity-dependent increase in the efficacy of synaptic transmission. In concert with long-term depression (LTD), this synaptic plasticity likely underlies some types of learning and memory. It has been suggested that for LTP/LTD to act as effective memory storage mechanisms, homeostatic regulation is required. This need for plasticity regulation is incorporated into the Bienenstock, Cooper and Munro (BCM) theory by a threshold determining LTD/LTP induction, which is altered by the previous history of activity (Bienenstock et al., 1982).

Aging is associated with adverse structural and functional changes in the brain. These changes have been directly linked to declines in certain types of learning and memory, likely due to the negative impact of aging on the hippocampus, a region necessary for cognitive functions such as relational learning, memory, and spatial navigation. Health behaviors and characteristics, like exercise and cardiorespiratory fitness (CRF), are related to better brain and cognitive aging, though more research is needed to better understand which age-sensitive aspects of cognitive function are most benefited

The aim of this doctoral thesis was to study neuropsychological function in relation to structural and functional brain changes in Alzheimer´s disease (AD). In the first study relations between hippocampal volume, neuropsychological function and limbic-hypothalamic-pituitary-adrenal (LHPA) axis disturbances in AD were investigated with magnetic resonance imaging (MRI). Reduced hippocampal CA1 volume and suppressed cortisol levels in combination, best predicted the variation in neuropsychological performance. The conclusion was that reduced hippocampal volume and LHPA axis disturbances are asso

Recent research, that has been focused on recognition memory, has revealed that two processes contribute to recognition of previously encountered items: recollection and familiarity (Aggleton & Brown, 1999; Eichenbaum, 2006; Eichenbaum, Yonelinas, & Ranganath, 2007; Rugg & Yonelinas, 2003; Skinner & Fernandes, 2007; Squire, Stark, & Clark, 2004; Wixted, 2007a; Yonelinas, 2001a; Yonelinas, 2002). The findings of neural correlates of recollection and familiarity lead to the assumption that there are different brain regions activated in either process, but there are, to the best of my knowledge,

La mémoire épisodique, notre capacité de se rappeler des épisodes particuliers de notre vie, a été initialement définie chez l'homme en termes de l'information qu'elle contient, quel événement a eu lieu, où et dans quel contexte /quand s'est-il produit? La démonstration de l'existence de cette forme de mémoire chez l'animal a été réalisée chez le geais buissonnier. En effet, cet oiseau cacheur est capable de former une représentation mentale complexe du type de nourriture qu'il a caché, où et quand. Cette forme de mémoire qualifiée d' « episodic-like » a depuis une dizaine d'année été établie

The hippocampal formation has been implicated in spatial formation for many decades. The hippocampus proper has received the most attention but other regions of the hippocampal formation contribute largely to spatial cognition. This thesis concentrated on one such region, the postsubiculum. The postsubiculum is considered important because it contains head direction cells and because it thought to be a major input to the hippocampus, via the entorhinal cortex. This thesis aims to test the functional role of the rat postsubiculum under two types of situation: one where the rat must rely on idio

Annotation:

In the late 90’s, emerging evidence revealed that the brain is insulin-sensitive, highlighted by broad expression of brain-specific insulin receptors and reports of circulating brain insulin. Contemporary literature robustly supports the role of insulin signaling in normal brain function and suggests that insulin-related processes diminish with aging, evidenced by decreased signaling markers, reduced insulin receptor density, and lower levels of insulin transport across the blood-brain barrier. In the context of pathological cognitive decline, clinical trials using intranasal insulin delivery
