Hi list, in Wakana et al., 2007, the SLF was divided in parietal and temporal components. As I understand it, the same subdivision has been made in Yendiki et al, 2011. In details, SLFp should correspond to SLF III and SLFt to arcuate fascicle.Tractography studies showed that the anatomy of the arcuate fasciculus is very complex (Catani et al., 2008). Additionally to direct segment connecting Wernicke’s area with Broca’s area, there is an indirect pathway consisting of two segments, an anterior segment frontal cortex to the inferior parietal lobule (also defined as SLFIII, Urbanski et al., 2011) and a posterior segment linking the inferior parietal lobule with temporal cortex. Becouse the physiological role of these tracts is different, I wonder to know which of these tracts correspond to SLFt? Thank you very much!
