Olfactory discrimination and memory deficits in the Flinders Sensitive Line rodent model of depression
2017
Major Depressive Disorder (MDD) is a heterogeneous psychiatric disorder with broad symptomatic manifestations. The current study examined, for the first time, olfactory memory and discrimination in the Flinders Sensitive Line (FSL) rodent model of depression. Male FSL rats and controls were trained on an Olfactory Discrimination (OD) and a Social Interaction (SI) test. On the OD test, the FSL and controls performed similarly at the shortest inter-trial interval (5min), however, with extended delay of 30min, the FSLs had a recall and odour discrimination deficit. At the longest delay (60min) both groups performed poorly. The FSL rats i.) had a deficit in olfactory discrimination suggesting i…
Total Sugar Intake and Macro and Micronutrients in Children Aged 6-8 Years: The Aniva Study
2020
The objective of this study was to study the association between total sugar intake (TSI) levels of children aged 6-8 years old, nutrient intake and anthropometry. Food and beverage intakes were collected by a prospective three-day recall questionnaire. The 2237 children were distributed into three groups according to TSI percentiles. Mean TSI was 93.77 ±
Recollection in adolescents with Autism Spectrum Disorder.
2013
Abstract Introduction Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder primarily affecting social interaction and communication. Recently, there has been interest in whether people with ASD also show memory deficits as a result of abnormal brain development. However, at least in adolescents with ASD, the recollection component of episodic memory has rarely been explored. This paper is an evaluation of recollection in three different experiments in adolescents with ASD, using both objective (source discrimination) and subjective methods (Remember–Know judgments). Methods Three experiments were designed to measure different aspects of contextual information: sensory/perceptual …
Independence of first- and second-order memories in newborn rabbits
2011
WOS:000291649400006; International audience; The mammary pheromone promotes the acquisition of novel odorants (CS1) in newborn rabbits. Here, experiments pinpoint that CS1 becomes able to support neonatal learning of other odorants (CS2). We therefore evaluated whether these first- and second-order memories remained dependent after reactivation. Amnesia induced after CS2 recall selectively blocked this memory, when recall and amnesia of CS1 left the souvenir of CS2 safe; this finding partially differed from results obtained in adult mammals. Thus, in this model of neonatal appetitive odor learning, second-order memory seems to depend on first-order memory for its formation but not for its m…
Working memory and children’s use of retrieval to solve addition problems
2005
This study tested the hypothesis that children with high working memory capacities solve single-digit additions by direct retrieval of the answers from long-term memory more often than do children with low working memory capacities. Counting and reading letter span tasks were administered to groups of third-grade (mean age=107 months) and fourth-grade (mean age=118 months) children who were also asked to solve 40 single-digit additions. High working memory capacity was associated with more frequent use of retrieval and faster responses in solving additions. The effect of span on the use of retrieval increased with the size of the minimum addend. The relation between working memory measures …
Recollection and familiarity in dense hippocampal amnesia: A case study
2004
In the amnesia literature, disagreement exists over whether anterograde amnesia involves recollective-based recognition processes and/or familiarity-based ones depending on whether the anatomical damage is restricted to the hippocampus or also involves adjacent areas, particularly the entorhinal and perirhinal cortices. So far, few patients with well documented anatomical lesions and detailed assessment of recollective and recognition performance have been described. We report a comprehensive neuroanatomical assessment and detailed investigation of the anterograde memory functions of a previously described severe amnesic patient (VC). The results of four previously published neuroradiologic…
Fractionation of memory in medial temporal lobe amnesia
2006
We report a comprehensive investigation of the anterograde memory functions of two patients with memory impairments (RH and JC). RH had neuroradiological evidence of apparently selective right-sided hippocampal damage and an intact cognitive profile apart from selective memory impairments. JC, had neuroradiological evidence of bilateral hippocampal damage following anoxia due to cardiac arrest. He had anomic and "executive" difficulties in addition to a global amnesia, suggesting atrophy extending beyond hippocampal regions. Their performance is compared with that of a previously reported hippocampal amnesic patient who showed preserved recollection and familiarity for faces in the context …
Effects of a simple reminiscence intervention program on the reminiscence functions in older adults
2020
ABSTRACTObjectives:Reminiscence promotes the acceptance of oneself and others, a sense of meaning, and the integration of the present and the past. The currently accepted classification contains eight reminiscence functions grouped in three broader functions: self-positive functions (identity, problem-solving, and death preparation); self-negative functions (bitterness revival, boredom reduction, and intimacy maintenance); and prosocial functions (conversation and teach-inform). The main objective of this study was to investigate how the eight dimensions change over time in a sample of healthy older adults after an intervention based on simple reminiscence and subsequent follow-up.Design:Pa…
Increased hippocampal head diffusivity predicts impaired episodic memory performance in early Alzheimer's disease
2010
Recent neuroanatomical and functional neuroimaging studies indicate that the anterior part of the hippocampus, rather than the whole structure, may be specifically involved in episodic memory. In the present work, we examined whether anterior structural measurements are superior to other regional or global measurements in mapping functionally relevant degenerative alterations of the hippocampus in Alzheimer's disease (AD). Twenty patients with early AD (MMSE 25.7+/-1.7) and 18 healthy controls were studied using magnetic resonance and diffusion-tensor imaging. Using a regions-of-interest analysis, we obtained volumetric and diffusivity measures of the hippocampal head and body-tail-section …
Disordered recognition memory: recollective confabulation.
2013
Recollective confabulation (RC) is encountered as a conviction that a present moment is a repetition of one experienced previously, combined with the retrieval of confabulated specifics to support that assertion. It is often described as persistent deja vu by family members and caregivers. On formal testing, patients with RC tend to produce a very high level of false positive errors. In this paper, a new case series of 11 people with dementia or mild cognitive impairment (MCI) and with deja vu-like experiences is presented. In two experiments the nature of the recognition memory deficit is explored. The results from these two experiments suggest - contrary to our hypothesis in earlier publi…
