Dorsal view of a fat-tailed dunnart brain, after magnetic resonance imaging and tractography reconstruction. Tracts were generated by parcellating the midsagittal anterior commissure (ac) into five segregated color-coded domains, each labeling homotopic contralateral connections between the olfactory bulbs (OB), frontal cortex (Fr), neocortex (NCx) and entorhinal cortex (Ent)
