Lesion-mapping study uncovers dual neural systems for error monitoring after stroke, suggesting complex hemispheric interactions govern verbal and spatial task accuracy.
Post-stroke performance monitoring involves two distinct neural systems. One is a domain-general system, probably centered in the right inferior frontal region, that supports overall accuracy. The other is a widely distributed, reverse lateralized system, with left lesions associated with spatial accuracy and right lesions associated with verbal accuracy. This suggests that performance monitoring relies on more complex hemispheric interactions than traditional models suggest.
