Table 2. Projection pathways connecting brainstem dAAN nodes with thalamic, hypothalamic, and basal forebrain dAAN nodes, as well as cortical DMN nodes.

For connections that met both the probabilistic and deterministic criteria for a structural connection, we assessed the deterministic fiber tracts linking each pair of nodes for their anatomic trajectories and classified them using previously defined nomenclature (9, 54): DTT_L = dorsal tegmental tract, lateral division; DTT_M = dorsal tegmental tract, medial division; LFB = lateral
