abnormal olfactory bulb morphology ( J:90716 )
• novel glomeruli form ventrally to endogenous P3 glomeruli, and are separated by 2-3 glomeruli; shift is not as greater as P4-P2 glomeruli shift relative toP4 glomeruli
abnormal olfactory neuron innervation pattern ( J:90716 )
• mutant axons do not reroute to P3 glomeruli
