Schematic diagram showing the topographic and layer-specific projections from the ACC to the amygdala. Projections from the pgACC (a; green), sgACC (b; orange), and dACC (c; magenta) to the BA and AcBA. Superficial and deep-layer projections are depicted by dotted and solid lines, respectively. Varying arrow thickness represents the relative intensity of projections. All abbreviations are as in Figure 1.
