How Flexible is the Use of Egocentric Versus Allocentric Frame of Reference in the Williams Syndrome Population? [PDF]

Archives of Clinical Neuropsychology, 2017
This study examined the spontaneous use of allocentric and egocentric frames of reference and their flexible use as a function of instructions.The computerized spatial reference task created by Heiz and Barisnikov (2015) was used. Participants had to choose a frame of reference according to three types of instructions: spontaneous, allocentric and ...

The Critical Role of Head Movements for Spatial Representation During Bumblebees Learning Flight

Frontiers in Behavioral Neuroscience, 2021
Bumblebees perform complex flight maneuvers around the barely visible entrance of their nest upon their first departures. During these flights bees learn visual information about the surroundings, possibly including its spatial layout.

Editorial: Perceiving and Acting in the real world: from neural activity to behavior [PDF]

, 2016
The interaction between perception and action represents one of the pillars of human evolutionary success. Our interactions with the surrounding world involve a variety of behaviors, almost always including movements of the eyes and hands.

The Use of Egocentric and Allocentric Reference Frames in Static and Dynamic Conditions in Humans

Physiological Research, 2020
The dissociation between egocentric and allocentric reference frames is well established. Spatial coding relative to oneself has been associated with a brain network distinct from spatial coding using a cognitive map independently of the actual position.

Entorhinal-retrosplenial circuits for allocentric-egocentric transformation of boundary coding

eLife, 2020
Spatial navigation requires landmark coding from two perspectives, relying on viewpoint-invariant and self-referenced representations. The brain encodes information within each reference frame but their interactions and functional dependency remains ...

Functional and Structural Architectures of Allocentric and Egocentric Spatial Coding in Aging: A Combined DTI and fMRI Study

Frontiers in Neurology, 2022
BackgroundAging disrupts the optimal balance between neural nodes underlying orienting and attention control functions. Previous studies have suggested that age-related changes in cognitive process are associated to the changes in the myelinated fiber ...

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.

The contributions of egocentric and allocentric reference frames in haptic spatial tasks

Acta Psychologica, 2004
The influence of egocentric and allocentric reference frames on performance in haptic spatial tasks, was tested in three conditions. Blindfolded subjects had to make two bars haptically parallel, perpendicular or mirrored in the midsagittal plane. The hypothesis is that the contributions of egocentric and allocentric reference frames are combined ...

Spatial hyperschematia without spatial neglect after insulo-thalamic disconnection. [PDF]

PLoS ONE, 2013
Different spatial representations are not stored as a single multipurpose map in the brain. Right brain-damaged patients can show a distortion, a compression of peripersonal and extrapersonal space.

Alice in wonderland syndrome. a clinical and pathophysiological review [PDF]

, 2016
Alice in Wonderland Syndrome (AIWS) is a perceptual disorder, principally involving visual and somesthetic integration, firstly reported by Todd, on the literary suggestion of the strange experiences described by Lewis Carroll in Alice in Wonderland ...
