Olfactory system glomeruli

Fig. 2 Axonal projection in the mouse olfactory system, a The transgenic mouse, MOR28-IRES-tau-lacZ (Serizawa et al. 2000), stained with X-gal (lateral view). Olfactory sensory neurons (OSNs) expressing the taw-/acZ-tagged MOR28 gene project their axons to a specific site forming a glomerulus in the olfactory bulb (OB), b Spatial correlation between the olfactory epithelium (OE) and the OB in the mouse olfactory system. OSNs in the dorsomedial zone (D zone) in the OE project their axons to the dorsal domain (D domain) of the OB. Class I ORs are mostly expressed by OSNs in the D zone in the OE, which target the anterodorsal cluster of the D domain in the OB. In the ventrolateral zone (V zone), each class II OR possesses its own unique expression...
