Figure 1. Representative phaseolus vulgaris leucoagglutinin (PHA-L) injection sites within the anterior olfactory nucleus (AON).

Figure 1

A) Schematic drawing of a coronal section through the AON, showing the relative location of subdivisions. Injections were targeted to layer II (dotted line) of the AON in pars medialis (AONm; B), pars dorsalis (AONd; C), pars ventralis (AONv; D) and pars lateralis (AONl; E), between 4.2 and 4.8 mm anterior to bregma. In all cases, the region of uptake was limited to cells within the boundaries of these subregions as described by Haberly and Price (1978b). The inset in panel B shows a magnified, contrast-enhanced view of the illustrated injection into pars medialis. Injections into this region were carefully examined to ensure that no cells within the adjacent olfactory bulb (to the left of the dashed line) displayed PHA-L uptake. LOT, lateral olfactory tract; PFC, prefrontal cortex; asterisk, olfactory ventricle; scale bar in B = 100 μm for panels B-E, 250 μm for inset in B.
