Fig. 5.

Projection pathways (left) connect brainstem nodes to hypothalamic, thalamic, and basal forebrain nodes. Commissural pathways (middle) connect contralateral brainstem nodes. Association pathways (right) connect ipsilateral and/or midline brainstem nodes. Brainstem dAAN nodes are shown in the outer ring of all connectograms. In the projection connectogram, the hypothalamic, thalamic and basal forebrain nodes are shown in the center: TMN = tuberomammillary nucleus; LHA = lateral hypothalamic area; IL = intralaminar nuclei; Ret = reticular nuclei; PaV = paraventricular nuclei; BNM/SI = nucleus basalis of Meynert/substantia innominata; DBB = diagonal band of Broca. Line thicknesses in each connectogram is proportional to the connectivity probability (CP) value derived from probabilistic tractography analysis. For clarity of visualization, interspecimen mean in CP measurements is shown in the connectograms. In the commissural connectogram, we show the connections from left-to-right and omit the right-to-left connections for ease of visualization. In the association connectogram, we take a mean of left- and right-sided connectivity for bilaterally represented nodes. We do not show a connectogram for projection pathways to the DMN nodes because the connectivity probability values are lower than for diencephalic and forebrain projection pathways (Table S10), such that connections would not be visualizable at this scale.
