This study investigates how galvanic vestibular stimulation (GVS) affects the perception of upright body orientation, finding that right-sided anodal GVS alters the Subjective Postural Vertical (SPV) in both young and older adults.

This study identifies head positions in MRI scanners that minimize magnetic vestibular stimulation effects by eliminating vestibulo-ocular reflex components through specific pitch and roll angles.

This study investigates optic ataxia in patients with thalamic lesions, finding that multiple thalamic nuclei, particularly in the central thalamus, contribute to visually guided reaching deficits.

This study examines how white matter hyperintensities (WMH) contribute to post-stroke spatial neglect by analyzing structural disconnections and their predictive power for neglect severity.

This study examines the time course and aftereffects of MVS-induced spatial attention bias and VOR in a 3T MRI scanner, showing sustained attention bias and temporary aftereffects.

The paper investigates spatial neglect in subcortical stroke and finds that disconnection of long cortico-cortical association fibres predicts the condition, without requiring subcortical grey matter involvement.

The paper uses Bayesian and frequentist analyses to assess neural dissociation between finger and hand imitation deficits in stroke patients, finding biases in pooled samples.

This paper shows that analyzing structural disconnections separately by hemisphere is more accurate than joint analysis, as joint analysis biases against intra-hemispheric disconnections.

The paper investigates brain disconnection in pusher syndrome using functional and structural measures in stroke patients, identifying thalamo-cortical network dysfunction as a likely cause.

This study examines how digital formats affect spatial neglect test behavior and finds the CoC measure is robust to digitization, while additional search behavior metrics can help differentiate neglect patients.

This study investigates the cause of line bisection bias in spatial neglect patients, finding that it is due to left-side underawareness rather than right-side hyperattention or logarithmic perception.

This study shows that lying in a 3T MRI scanner with feet first reduces spatial neglect in stroke patients by counteracting their attentional bias.

This study investigates the role of posterior ventral stream areas in viewpoint-invariant object recognition using fMRI and patient studies, finding increased activity in fusiform and lateral-occipital regions for atypical views.

The paper maps structural white matter disconnections in apraxia by analyzing diffusion tensor imaging data from stroke patients, identifying key fronto-temporo-parietal and subcortical networks involved.

The paper investigates how disconnections in left-hemispheric brain areas, particularly the angular gyrus, affect arithmetic fact retrieval following stroke.

This study shows that being in a 3T MRI scanner causes a rightward shift in spatial attention, similar to spatial neglect in stroke patients.

The paper investigates the role of temporo-parietal brain regions in object perception, finding that these areas are involved in processing non-canonical object orientations and global shapes.

The paper re-analyzes the anatomical basis of pathological line bisection using multivariate lesion-symptom mapping in stroke patients, finding multiple lesion locations and white matter damage contribute to the error.

The paper assesses whether lesion information beyond the primary motor system can predict motor outcomes after stroke, finding that such information improves prediction even when the biomarker is based on corticospinal tract damage.

This study confirms right-hemisphere predominance of lesions in lesional mania and identifies specific brain regions associated with mood regulation.

This study uses multivariate lesion-behaviour mapping to identify a common anatomical network for higher-order motor control in apraxia of pantomime.

This study uses multivariate lesion-mapping to identify a brain network associated with spatial neglect and attention in right brain damaged patients, showing benefits over univariate methods.

This study evaluates SVR-LSM for multivariate lesion behaviour mapping, finding that multiple comparison correction, sufficient sample size, and susceptibility to vascular misplacement are critical methodological considerations.
