• neural
  • We compared the behavioral effects and neural systems of memory-guided orienting with those in a more traditional attention-orienting task in which transient spatial cues guide attention. (ox.ac.uk)
  • Study III used psychophysiology and fMRI to localize the functional neural activity mediating the fear memory reconsolidation disruption effect. (diva-portal.org)
  • Humans
  • The study, published today in the advance online issue of Nature Neuroscience , provides the first direct evidence that one component of age-related memory decline in humans is caused by changes in a specific region of the brain and that this form of memory decline can be improved by a dietary intervention. (womensbrainhealth.org)
  • To see if the dentate gyrus is the source of age-related memory decline in humans, Dr. Small and his colleagues tested whether compounds called cocoa flavanols can improve the function of this brain region and improve memory. (womensbrainhealth.org)
  • This thesis examines the attenuation of fear memories by disrupting reconsolidation in humans, using measures of both the central and peripheral nervous system activity. (diva-portal.org)
  • Study I examined the attentuation of fear memories by disrupting reconsolidation in humans using reacquisition as a measure of the return of fear. (diva-portal.org)
  • brain
  • Event-related functional magnetic resonance imaging showed that memory-guided attention involves the interaction between brain areas participating in retrieval of memories for spatial context with the parietal-frontal network for visual spatial orienting. (ox.ac.uk)
  • This is an improvement over the multi-store model of memory because it is more detailed, and therefore we can learn more about the stores of memory in the brain from it. (markedbyteachers.com)
  • Previous work, including by the laboratory of senior author Scott A. Small, MD, had shown that changes in a specific part of the brain-the dentate gyrus-are associated with age-related memory decline. (womensbrainhealth.org)
  • Brain imaging and memory tests were administered to each participant before and after the study. (womensbrainhealth.org)
  • The brain imaging measured blood volume in the dentate gyrus, a measure of metabolism, and the memory test involved a 20-minute pattern-recognition exercise designed to evaluate a type of memory controlled by the dentate gyrus. (womensbrainhealth.org)
  • evaluate
  • In order to evaluate the possible role of fear memory reconsolidation mechanims in the effect on fear and anxiety by these genes, this thesis also compare the reconsolidation disruption effect between different serotonergic and dopaminergic genotypes. (diva-portal.org)
  • long-term m
  • Orienting attention based on long-term memory experience. (ox.ac.uk)
  • Here we introduce an experimental paradigm using naturalistic scenes to investigate how long-term memory can guide spatial attention and thereby enhance identification of events in the perceptual domain. (ox.ac.uk)
  • The phonological store receives its input either directly from the ears or from long term memory. (markedbyteachers.com)
  • input is from the eyes or long term memory. (markedbyteachers.com)
  • complex
  • In the task, stable memories of objects embedded within complex scenes guide spatial orienting. (ox.ac.uk)
  • This model was an alternative to Atkinson & Shiffrin's 'multi-store' memory model (1968) to show that short-term memory was actually a lot more complex than the MSM (multi-store model) had previously suggested. (markedbyteachers.com)
  • role
  • The working model proposes an active, multi-component short-term memory store with each sub-system having its own role to play in learning, problem solving and concentration. (markedbyteachers.com)
  • study
  • Dietary cocoa flavanols-naturally occurring bioactives found in cocoa-reversed age-related memory decline in healthy older adults, according to a study led by Columbia University Medical Center (CUMC) scientists. (womensbrainhealth.org)
  • If a participant had the memory of a typical 60-year-old at the beginning of the study, after three months that person on average had the memory of a typical 30- or 40-year-old," said Dr. Small. (womensbrainhealth.org)
  • Study II also investigated the impact of differences in serotonergic and dopaminergic alleles on the process of fear memory reconsolidation. (diva-portal.org)
  • Activity
  • Activity in the hippocampus was specifically engaged in memory-guided spatial attention and correlated with the ensuing behavioral advantage. (ox.ac.uk)
