E14 to E15 and survival to postnatal day (P)5 (posterior)

Figure 14 is a slice from the same specimen that cuts through the accessory olfactory bulb (AOB) dorsally, the main olfactory bulb (MOB) medially, and the anterolateral part of the anterior olfactory nucleus.  Like the P21 survival specimen in Figure 13, labeling patterns in the AOB and MOB show many unlabeled AOB output neurons, more densely labeled AOB granule cells, many labeled MOB mitral cells and lightly to no label in the MOB granule cells.  By P5, there is a more definite separation between the AOB and MOB granule cells than at E21.  On the morning of E14 neurogenesis is occurring in the AOB, so we should see some cell accumulations in an AOB primordium in E14 embryos.
