Most arom+ neuron populations in the brain do not project back to the AOB. A, Fluorogold (cyan) was microinjected in the AOB of arom+ reporter mice to retrogradely label AOB projecting neurons in the brain. B, Slices from major populations of arom+ neurons spanning the anterior to posterior axis of the brain were analyzed. C, Injections of fluorogold in the AOB retrogradely labeled AOB projecting neurons (cyan) near, but not including, arom+ populations (red) in the brain. D, Thirteen brain regions were identified that had either large populations of arom+ neurons (red) or large populations of AOB projecting neurons (cyan); however, most regions lacked statistically significant co-labeling of fluorogold with arom+ (pink; P > 0.5; one-sample t-test with Bonferroni correction).
