Odorant Receptors Signaling Instructs the Development and Plasticity of the Glomerular Map

Figure 2

Regionalization of OSN populations in the OE and the corresponding position of glomeruli in the OB. (a) There is a gradational regionalization of the different OSN populations across the dorsoposterior-ventroanterior axis. A dorsoventral correspondence of glomerular position holds up in the OB. (b) The lateral view of the OB of a M72-tau-LacZ mouse is shown. M72 neurons are located in the dorsoposterior OE and the M72 glomerulus in the dorsal part of the OB. Beta-galactosidase (blue) activity was revealed by X-gal.
