Spatial Navigation Based on Novelty Mediated Autobiographical Memory [chapter]

Emilia Barakova, Tino Lourens
2005 Lecture Notes in Computer Science  
The experimental results show that learning mediated by novelty provides a flexible and efficient way to encode spatial information in its contextual relatedness and directionality.  ...  The episodic and autobiographical memories are modelled to resemble the memory formation process that takes place in the rat hippocampus.  ...  Formation of the remembered episodes is mediated by novelty/familiarity discrimination method based on the hippocampal modelling for robotics exploration.  ...

A Prefrontal-Hippocampal Comparator for Goal-Directed Behavior: The Intentional Self and Episodic Memory

Robert Numan
2015 Frontiers in Behavioral Neuroscience  
One theory which describes a prefrontal-hippocampal comparator for voluntary action is emphasized.  ...  Such a perspective can be applied to episodic memory in humans, and episodic-like memory in non-human animal species.  ...  All rats learned this "source memory" by discriminating food areas based on passive placement vs. active movement.  ...

Nonhuman primate models of hippocampal development and dysfunction

Jocelyne Bachevalier
2019 Proceedings of the National Academy of Sciences of the United States of America  
The results provide significant information on the emergence of hippocampal-dependent functions in humans, on the time course of memory impairment in human cases with early hippocampal insult, and on the  ...  Finally, the early hippocampal insult resulted in both adaptive and maladaptive neuroplasticity: i.e., sparing contextual memory, but affecting working memory processes as well as emotional reactivity  ...  memory, or autobiographical memory (1) .  ...

The hippocampus as a "stupid," domain-specific module: Implications for theories of recent and remote memory, and of imagination

Morris Moscovitch
2008 Canadian journal of experimental psychology  
These, in turn, have important implications for neuropsychological theories of recent and remote episodic, semantic, and spatial memory and for the functions that episodic memory may serve in perception  ...  I consider these implications by selectively reviewing the literature and primarily drawing on research my collaborators and I have conducted.  ...  allocentric spatial information needed for navigation.  ...

Anterior hippocampus: the anatomy of perception, imagination and episodic memory

Peter Zeidman, Eleanor A. Maguire
2016 Nature Reviews Neuroscience  
In this Opinion article, we capitalize on new findings from functional neuroimaging to propose a model that links high-level cognitive functions to specific structures within the anterior hippocampus.  ...  based on local visual features ('state-based perception').  ...  Novelty and encoding. The anterior hippocampus responds to novelty, particularly of spatial stimuli.  ...

Hippocampal activation during retrieval of spatial context from episodic and semantic memory

Siobhan M. Hoscheidt, Lynn Nadel, Jessica Payne, Lee Ryan
2010 Behavioural Brain Research  
On the other hand, recent neuroimaging studies of intact individuals report hippocampal activation during retrieval of both autobiographical memories and semantic information that includes historical facts  ...  The hippocampus, a region implicated in the processing of spatial information and episodic memory, is central to the debate concerning the relationship between episodic and semantic memory.  ...  on spatial location and navigation through space.  ...

Choong-Hee Lee, Jungwon Ryu, Sang-Hun Lee, Hakjin Kim, Inah Lee
2016 Hippocampus  
The hippocampus plays critical roles in both object-based event memory and spatial navigation, but it is largely unknown whether the left and right hippocampi play functionally equivalent roles in these  ...  retrieval of relatively pure spatial memory (spatial memory period) was correlated with the right hippocampal BOLD response.  ...  Acknowledgments The authors thank James Knierim and Randolph Blake for helpful comments and discussions on earlier versions of the manuscript. The authors declare no competing financial interests.  ...

Navigating Social Space

Matthew Schafer, Daniela Schiller
2018 Neuron  
Research now indicates that social life can also be mapped by these mechanisms: others' spatial locations, social memory, and even a two-dimensional social space framed by social power and affiliation.  ...  The systematic mapping of social life onto a relational social space facilitates adaptive social decision making, akin to social navigation.  ...  Speculating from this evidence, PCC grid-like representations might compute social distance, which in turn informs autobiographical memory-mediated mental state inferences.  ...
