Abstract:
Unilateral spatial neglect (USN) significantly impairs mobility in patients following a stroke. The amount and quality of evidence supporting effective treatments for USN is still limited, primarily due to the unclear nature of its underlying neural mechanisms. As lesions in USN are not localized to a specific brain region, research has underscored the importance of evaluating USN from a network-based perspective. Nevertheless, the key functional regions at the core of this network are yet to be identified. Previously, we reported that the right inferior parietal lobule (IPL) may serve as the central hub in the neural network associated with USN. Therefore, this study aimed to determine the brain network centered on the right IPL by conducting seed-based functional connectivity analysis. Our results may contribute to a better understanding of the neural mechanisms in USN.
