The prognosis of allocentric and egocentric neglect : evidence from clinical scans [PDF]

, 2012
We contrasted the neuroanatomical substrates of sub-acute and chronic visuospatial deficits associated with different aspects of unilateral neglect using computed tomography scans acquired as part of routine clinical diagnosis.

Allocentric spatial performance higher in early-blind and sighted adults than in retinopathy-of-prematurity adults [PDF]

, 2016
The question as to whether people totally blind since infancy process allocentric or ‘external’ spatial information like the sighted has caused considerable debate within the literature. Due to the extreme rarity of the population, researchers have often

Egocentric and Allocentric Representations in Auditory Cortex [PDF]

PLOS Biology, 2017
Abstract A key function of the brain is to provide a stable representation of an object’s location in the world. In hearing, sound azimuth and elevation are encoded by neurons throughout the auditory system and auditory cortex is necessary for sound localization.

Daytime sleep enhances consolidation of the spatial but not motoric representation of motor sequence memory. [PDF]

PLoS ONE, 2013
Motor sequence learning is known to rely on more than a single process. As the skill develops with practice, two different representations of the sequence are formed: a goal representation built under spatial allocentric coordinates and a movement ...

Egocentric and allocentric spatial memory in healthy aging: performance on real-world tasks

Brazilian Journal of Medical and Biological Research, 2019
Although normal aging has been related to several cognitive difficulties, other processes have been studied less, such as spatial memory. Our aim was to compare egocentric and allocentric memory in an elderly population using ecological tasks.

Perceptual History Acts in World-Centred Coordinates

i-Perception, 2021
Serial dependence effects have been observed using a variety of stimuli and tasks, revealing that the recent past can bias current percepts, leading to increased similarity between two.

Route repetition and route retracing: effects of cognitive aging [PDF]

, 2012
Retracing a recently traveled route is a frequent navigation task when learning novel routes or exploring unfamiliar environments. In the present study we utilized virtual environments technology to investigate age-related differences in repeating and ...

Neural substrates of visual spatial coding and visual feedback control for hand movements in allocentric and target-directed tasks

Frontiers in Human Neuroscience, 2011
Neuropsychological evidence suggests that different brain areas may be involved in movements that are directed at visual targets (e.g. pointing or reaching), and movements that are based on allocentric visual information (e.g. drawing or copying).

Basal Forebrain Atrophy Is Associated With Allocentric Navigation Deficits in Subjective Cognitive Decline

Frontiers in Aging Neuroscience, 2021
Individuals with subjective cognitive decline (SCD) are at higher risk of incipient Alzheimer's disease (AD). Spatial navigation (SN) impairments in AD dementia and mild cognitive impairment patients have been well-documented; however, studies ...

Egocentric and allocentric spatial memory in typically developed children: Is spatial memory associated with visuospatial skills, behavior, and cortisol?

Brain and Behavior, 2020
Introduction Spatial orientation relies mainly on two frameworks. The egocentric depends on our own position and point of view. The allocentric relies on remembering, recalling, and recognizing environmental stimuli called landmarks.
