Allocentric and egocentric reference frames in the processing of three-dimensional haptic space [PDF]

Experimental Brain Research, 2008
The main goal of our study is to gain insight into the reference frames involved in three-dimensional haptic spatial processing. Previous research has shown that two-dimensional haptic spatial processing is prone to large systematic deviations. A weighted average model that identifies the origin of the systematic error patterns in the biasing influence

The Two-Wrongs model explains perception-action dissociations for illusions driven by distortions of the egocentric reference frame

Frontiers in Human Neuroscience, 2015
Several studies have demonstrated a dissociation of the effects of illusion on perception and action, with perception generally reported to be susceptible to illusions, while actions are seemingly immune.

Navigating space and the developing mind [PDF]

Frontiers in Psychology
In this article, we review the extensive and complex fabric of literature concerning the ontogenesis of spatial representations from earliest childhood to the elderly, including normal and abnormal aging (dementia and Alzheimer’s disease).

Changing the influence of the egocentric reference frame impacts deviations in haptic parallelity matching [PDF]

Experimental Brain Research, 2019
The large systematic deviations in haptic parallelity matching are most likely due to the biasing influence of the hand-centered egocentric reference frame. Previous results showed that eliminating or reducing this bias resulted in smaller deviations, with significantly larger effects observed in female participants.

Distinct Neural Dynamics of Spatial Transformations: Egocentric Perspective-Taking and Allocentric Rotation [PDF]

Brain Sciences
Background/Objectives: Egocentric and allocentric spatial transformations are central to spatial cognition, yet it is unknown whether they rely on the same neural mechanisms. The goal of this study was to examine whether egocentric transformations engage

Sensing flow gradients is necessary for learning autonomous underwater navigation [PDF]

Nature Communications
Aquatic animals are much better at underwater navigation than robotic vehicles. Robots face major challenges in deep water because of their limited access to global positioning signals and flow maps.

Right parietal lesions, unilateral spatial neglect, and the egocentric frame of reference

NeuroImage, 2003
Recently, the hypothesis has been proposed that the crucial mechanism leading to neglect is the disturbed transformation of sensory input into a supramodal egocentric frame of reference (ER), which causes in turn a deviation of this reference frame toward the side ipsilateral to the brain lesion.

Whole-Body Roll Tilt Influences Goal-Directed Upper Limb Movements through the Perceptual Tilt of Egocentric Reference Frame

Frontiers in Psychology, 2018
In our day-to-day life, we can accurately reach for an object in our gravitational environment without any effort. This can be achieved even when the body is tilted relative to gravity.

Head direction cells use a head-referenced dual-axis updating rule in 3D space

Communications Biology
Head direction (HD) cells, comprising a compass signal for the brain’s spatial map, may update their firing during 3D movement by using a ‘dual axis’ (DA) rule that sums head rotation around a local axis and local-axis rotation around the gravity axis ...

Human spatial navigation: Neural representations of spatial scales and reference frames obtained from an ALE meta-analysis

NeuroImage, 2021
Humans use different spatial reference frames (allocentric or egocentric) to navigate successfully toward their destination in different spatial scale spaces (environmental or vista). However, it remains unclear how the brain represents different spatial
