Allocentric and egocentric spatial representations coexist in rodent medial entorhinal cortex

Nature Communications
Successful navigation relies on reciprocal transformations between spatial representations in world-centered (allocentric) and self-centered (egocentric) frames of reference.

Spatial memory deficit across aging: current insights of the role of 5-HT7 receptors

Frontiers in Behavioral Neuroscience, 2015
Elderly persons often face biological, psychological or social changes over time that may cause discomfort or morbidity. While some cognitive domains remain stable over time, others undergo a decline.

What is the role of spatial processing in the decline of episodic memory in Alzheimer's disease? The "mental frame syncing" hypothesis

Frontiers in Aging Neuroscience, 2014
The current theories on episodic memory suggest a crucial role of spatial processing for an effective retrieval. When prompted by a retrieval cue, the full past scene can be retrieved through the process of pattern completion.

Evidence for allocentric boundary and goal direction information in the human entorhinal cortex and subiculum

Nature Communications, 2019
In rodents, cells in the medial entorhinal cortex and subiculum are known to encode the allocentric direction to nearby walls and boundaries. Here, using fMRI the authors show that this is also true in humans, with allocentric boundary direction being ...

Spatial navigation in young versus older adults

Frontiers in Aging Neuroscience, 2013
Older age is associated with changes in the brain, including the medial temporal lobe, which may result in mild spatial navigation deficits, especially in allocentric navigation.

Antidepressant suppression of REM and spindle sleep impairs hippocampus-dependent learning and memory but fosters striatal-dependent strategies [PDF]

, 2011
REM sleep enhances hippocampus-dependent associative memory but has little impact on striatal-dependent procedural learning. Antidepressant medications like desipramine (DMI) inhibit rapid-eye-movement (REM) sleep but it is little understood how ...

Studying cities to learn about minds: some possible implications of space syntax for spatial cognition [PDF]

, 2009
What can we learn of the human mind by examining its products? The city is a case in point. Since the beginning of cities human ideas about them have been dominated by geometric ideas, and the real history of cities has always oscillated between the ...

Egocentric versus allocentric perspective - From spatial to social and digital cognition

Dialogues in Clinical Neuroscience & Mental Health
As mobile beings, it is important to maintain spatial information about our surroundings in everyday life. Neuroscience suggests the existence of two types of frames of reference in spatial memory: egocentric and allocentric representation.

Egocentric and allocentric memory recall strategies moderate transfer action sentence recognition

Language and Cognition
Embodied cognition theory proposes that spatial cognition preferences facilitate the simulation of action language. Importantly, spatial cognition relies on either egocentric (body-dependent) or allocentric (body-independent) representations.

Allocentric emotional affordances in HRI

, 2018
The concept of affordance perception is one of the distinctive traits of human cognition; and its application to robots can dramatically improve the quality of human-robot interaction (HRI). In this paper we explore and discuss the idea of "emotional affordances" by proposing a viable model for implementation into HRI; which considers allocentric and ...
