Frontal Aslant Tracts from Operculum and Insula Cortical Terminations

Description: Aslant connections from the superior frontal gyrus to the inferior frontal gyrus, and from the superior frontal gyrus to the insula. Segmented according to Brodmann areas segmented in Conte69 Brodmann atlas available from scalablebrainatlas.com, with each tract seeded from a superior frontal gyrus Brodmann area (BA4, 6, 8, 9 + BA3-1-2 for insula connections) to broad terminations in the inferior gyrus from pars triangularis, to pars opercularis, to the ventral portions of BA6, 4, 3, 1, 2 and BA43. These are tract density maps masked within grey matter segmentation generated from FSL FAST.
