I think the lines indicate highly connected/weighted network edges. The weights are inferred from white matter tracts, measured using diffusion MRI. Dots are nodes on the network, highly connected nodes are indicated by a pair of large dots.
- chaxor 3y agoSure, but this is unfortunately not really novel work in this area. White matter tract and (3T, typically not more) fMRI-based analyses of language tasks have been done for decades, and simply don't provide much information due to the horrendous resolution inherent to the task. What is needed in the area is something more similar to EPFL's in silico rat cortex reconstruction, only for humans. I haven't seen a single reference (ever) for single cell resolution information on connectivity in Wernicke's area (arguably the absolute most important and distinguishing cortex in human brain vs non-human primate). This is what is needed now, rather than extremely ham handed or crude, low resolution correlations across brain structures which are well established in many contexts.
