nervous system
abnormal axon fasciculation ( J:174418 )
• olfactory bulb axons project caudally in a defasciculated manner, resulting in significantly wider expansion of DiI staining in the lateral olfactory tract
• axonal bundling is decreased in cultured olfactory bulb axons
abnormal olfactory tract morphology ( J:174418 )
• olfactory bulb axons project caudally in a defasciculated manner, resulting in significantly wider expansion of DiI staining in the lateral olfactory tract
