nervous system
abnormal olfactory bulb development ( J:91160 )
• instead of converging into a glomeruli, axons of the olfactory bulb diverge and innervate widely dispersed glomeruli across the dorsal bulb
abnormal innervation ( J:91160 )
• olfactory neurons innervate preferentially OCAM- glomeruli
abnormal neuron morphology ( J:91160 )
• instead of converging into a glomeruli, axons of the olfactory bulb diverge and innervate widely dispersed glomeruli across the dorsal bulb
