Disruption of large-scale electrophysiological networks in stroke patients with visuospatial neglect

This study examines EEG source imaging in stroke patients with visuospatial neglect, finding altered cortical network organization and abnormal brain oscillations linked to neglect symptoms.

Lying in a 3T MRI Scanner Induces Neglect-Like Spatial Attention Bias

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

Behavioral rebound following isolation of attention

This study shows that isolating attention to one visual field leads to increased attention in the opposite visual field, suggesting a rebound effect due to attention rebalancing.

Callosal anisotropy predicts attentional network changes after parietal inhibitory stimulation

The paper investigates how inhibitory TMS over the right PPC affects visuospatial attention networks and finds that callosal anisotropy correlates with changes in resting-state functional connectivity.

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.

Attentional reorientation along the meridians of the visual field: are there different neural mechanisms at play?

The paper investigates whether attentional reorientation along horizontal and vertical visual field meridians involves different neural mechanisms using fMRI and behavioral data.

E-TAN, a technology-enhanced platform with tangible objects for the assessment of visual neglect: a multiple single-case study

E-TAN is a technology-enhanced platform for assessing visual neglect using an enhanced BTT, showing it can distinguish neglect patients from healthy controls.

Prism adaptation modulates connectivity of the intraparietal sulcus with multiple brain networks

This study shows that prism adaptation modulates brain connectivity in healthy individuals, with right PA increasing right-hemisphere network connectivity and left PA having opposite effects.
