Effect of painful and non-painful sensorimotor manipulations on subjective body midline

Frontiers in Human Neuroscience, 2013
Patients with chronic pain often show disturbances in their body perception. Understanding the exact role played by pain is however complex, as confounding factors can contribute to the observed deficits in these clinical populations.

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 ...

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.

Different effects of numerical magnitude on visual and proprioceptive reference frames

Frontiers in Psychology, 2013
This study assessed whether numerical magnitude affects the setting of basic spatial coordinates and reference frames, namely the subjective straight ahead.

Identifying a distractor produces object-based inhibition in an allocentric reference frame for saccade planning

Scientific Reports
We investigated whether distractor inhibition occurs relative to the target or fixation in a perceptual decision-making task using a purely saccadic response. Previous research has shown that during the process of discriminating a target from distractor,

Zen and the Brain: Mutually Illuminating Topics

Frontiers in Psychology, 2013
Zen Buddhist meditative practices emphasize the long-term, mindful training of attention and awareness during one’s ordinary daily-life activities, the shedding of egocentric behaviors, and the skillful application of one’s innate compassionate resources

Position- and scale-invariant object-centered spatial localization in monkey frontoparietal cortex dynamically adapts to cognitive demand

Nature Communications
Egocentric encoding is a well-known property of brain areas along the dorsal pathway. Different to previous experiments, which typically only demanded egocentric spatial processing during movement preparation, we designed a task where two male rhesus ...

Parallel Behind Your Head

i-Perception, 2018
A miniature hair clip set-up presented to the first author gave inspiration for this study. After a number of studies investigating what is haptically perceived as parallel on horizontal, frontoparallel or midsagittal planes, the present study focusses ...

Prisms to Shift Pain Away: Pathophysiological and Therapeutic Exploration of CRPS with Prism Adaptation

Neural Plasticity, 2016
Complex Regional Pain Syndrome (CRPS) is an invalidating chronic condition subsequent to peripheral lesions. There is growing consensus for a central contribution to CRPS.

Neuro-anatomical dissections of unilateral visual neglect symptoms: ALE meta-analysis of lesion-symptom mapping

Frontiers in Human Neuroscience, 2012
Unilateral visual neglect is commonly defined as impaired ability to attend to stimuli presented on the side of visual space contralateral to the brain lesion. However, behavioural analyses indicate that different neglect symptoms can dissociate.
