A) Schematic showing the four populations of ventral frontal cortex-projecting neurons analyzed here: BLA neurons targeting AI (yellow), mOFC (blue), lOFC (red), and vlPFC (green). A and P designate anterior and posterior directions, respectively; M and L refer to medial and lateral. B) Venn diagram illustrating projections to each area that also branch to the other three; AI-projecting neurons were least likely to branch to the other areas (z-test for proportions, z=4.425, p<0.0001), while vlPFC-projecting neurons were most likely to branch within ventral FC (z=2.476, p=0.0133). C) Likelihood of ventral frontal cortex-projecting neurons projecting to non-ventral frontal cortex targets. Populations are non-overlapping, such that we are excluding neurons that branch between mOFC, lOFC, vlPFC, and AI. See also Supplemental Figure 7.
