Diffusion Magnetic Resonance Imaging

 

Homologous cerebral grid structure in (A) galago, (B) marmoset, (C) owl monkey, (D) rhesus monkey, and (E) human, left lateral views.

 

Homologous grid structures including those of the corpus callosum/cingulum bundle (CC/CB); sagittal stratum and supra-Sylvian region were identified in all species, and that of the anterior commissure and fornix (AC/FX) was resolved in all ex vivo studies [(A) to (D)].

 

In the rhesus monkey, grid structure is shown in gyri and sulci, including the principal, arcuate, and central sulci and the superior temporal gyrus, continuous as grids with those of the adjacent deep white matter.
