From competition to cooperation: Visual neglect across the hemispheres

Visuospatial neglect is a frequent and disabling consequence of injuries to the right hemisphere. Patients with show signs impaired attention for left-sided events, which depends on dysfunction fronto-parietal networks. After unilateral injury, such as stroke, these networks their contralateral homologs can reorganize following multiple potential trajectories, be either adaptive or maladaptive. This article presents possible factors influencing profile evolution towards recovery chronicity, highlights mechanisms that may constrain processes in time space. The integrity white matter pathways within between hemisphere appears pose crucial connectivity constraints compensatory brain plasticity from remote regions. Specifically, availability sufficient degree inter-hemispheric might critical shift role undamaged left spatial neglect, exerting maladaptive effects, promoting activity.
