Brain network relevant to neglect

Background: The dysfunction of spatial attention leads to neglect. The underlying anatomical substrate is a matter of intense debate. In this context, the disruption of long associative pathways is considered as one possible explanation of neglect. Recent results in primates demonstrate that superior longitudinal (SLF) and the arcuate (AF) fascicles provide connectivity for the spatial attention system. However, in humans there are only few and incomplete experimental data concerning the connectivity of the spatial attention system. Our study aims at mapping the trajectories of white matter association pathways…
