摘要：Language comprehension impairments following stroke result potentially from a loss of cognitive control duringaccess to semantic representations. An increasingly popular hypothesis suggests that the left inferior frontal gyrus(LIFG) supports this form of cognitive control, directing activation of semantic representations underpinned by theanterior temporal lobes (ATL; Jefferies and Lambon-Ralph, 2006). Further, a white matter tract, the uncinate fasciulus(UF) connects regions within the LIFG and ATL. The aim of this study was to examine the relationship betweencomprehension impairments and the structural and functional connectivity profiles of areas hypothesized to beimportant for semantic processing.
