abnormal olfactory bulb morphology ( J:115911 )
• two pairs of glomeruli, the second ectopic and ventral to the normal glomeruli, are present in less than 20% of bulbs
• presence of extra glomeruli correlates to presence of fewer cells in dorsal regions and more cells in the ventral region of the epithelium of endoturbinates II and III
