E13+14 to P5 (POSTERIOR)
Figure 5 slices through the olfactory peduncle that has a medial sliver of the main olfactory bulb, the accessory bulb superficially and the anterior olfactory nucleus laterally. The Frontal pole of the cerebral cortex is on the left side of the slice. The accessory olfactory bulb output neurons are heavily labeled with an occasional cell unlabeled; nearly 10% of this population is generated before E13 so that some unlabeled cells are present. Labeling patterns in the main olfactory bulb match what appears in Figure 4.
