Sentences with phrase «episodic memory by»

Our findings contribute to the understanding of episodic memory by characterizing the mental chronometry of correct and incorrect retrievals, and providing further support for context based models of memory.

The team tested the participants» episodic memory by asking them to recall a list of words they viewed 20 minutes before.

After a pause, they tested episodic memory by asking the subjects to distinguish these words from new words.

Not exact matches

This speculation was sparked by two seemingly key coincidences of one, timing when this protein synthesis stage occurs coincides with the patient's forgetting at 90 minutes or thereabouts, and two, both «episodic» and «procedural» memories appear to require successful protein synthesis to occur for long - term memory permanence, and the patient can not retain any new either episodic or procedural memories — and this is unusual compared to traditional cases of amnesia.

The hippocampus — a region crucially involved in forming «episodic» memories (event recall) and spatial memory (for physical navigation)-- is especially affected by aging, with accompanying declines in the ability to learn and remember; it also deteriorates early on when afflicted by Alzheimer's.

The model developed by the three researchers Prof Markus Werning, Prof Sen Cheng (both Mercator Research Group «Structure of Memory» at RUB) and Prof Thomas Suddendorf (University of Queensland) differs from other approaches with regard to one major aspect: it suggests a new relationship between mental time travel and episodic mMemory» at RUB) and Prof Thomas Suddendorf (University of Queensland) differs from other approaches with regard to one major aspect: it suggests a new relationship between mental time travel and episodic memorymemory.

A new study by Indiana University researchers that appears online today in the journal Current Biology suggests that rats exhibit much stronger episodic memory than previously thought.

The finding may pave the way for new ways to prevent or reverse deficits in episodic memory, caused by aging or neurodegenerative diseases, such as Alzheimer's.

In a study published in the Philosophical Transactions of the Royal Society B, a team of researchers led by Professor Barbara Sahakian from the Department of Psychiatry at Cambridge describe how they developed and tested Wizard, an iPad game aimed at improving an individual's episodic memory.

By asking participants to recall the items they delivered instead of the stores they visited, the researchers could test whether their spatial memory systems were being activated even when episodic memories were being accessed.

The hippocampus is critical for episodic memory, and synaptic changes induced by long - term potentiation (LTP) are thought to underlie memory formation.

The results replicate previous findings, by showing superior episodic memory performance when looking at a congruent location, and further demonstrate that this facilitatory effect of gaze direction is associated with increased cortical desynchronization in the alpha / beta - band.

Based on evidence from electrophysiological studies showing that both synaptic plasticity and strength of inputs to hippocampal region CA1 vary systematically with ongoing theta oscillations (Hyman et al., 2003; Brankack et al., 1993), it has been suggested that the theta rhythm functions to separate periods of encoding of current sensory stimuli and retrieval of episodic memory cued by current stimuli so as to avoid interference that would occur if encoding and retrieval were simultaneous.

By contrast, «episodic memory» refers to the encoding of autobiographical information relating to a specific event that is located in time.

Time - series analysis of default - mode activity provides a measure of the degree to which a task engages a subject and whether it is sufficient to interrupt the processes — presumably cognitive, internally generated, and involving episodic memory — mediated by the default - mode network.

Which aspect of episodic memory (item, source) is enhanced by emotional memory consolidation during sleep, and which is the sleep stage (SWS or REM) that produces this enhancement?

However, a study conducted by the University of Montreal published in October 2013 indicated that high vitamin K levels improve episodic memory (the ability to recall information in the right space - time context).
