Figure 2.

Primate network diagram showing a subset of relevant brain areas and projections for visual fear signaling. Anatomical abbreviations are described in Table 1. The proposed fear signaling pathways are labeled p1–p5. Projection preferences 1–39 are listed in Table 2, which are not exhaustive. Hippocampus and most ACC circuits are excluded. The amygdala superficial cortical nuclei are also excluded. For clarity, PFC and ITC groups appear more than once. Projections may connect a nested group when there are multiple internal sources/destinations or the source/destination is uncertain.
