the data presented below indicate that neonatal infraorbital nerve transection has the following consequences within the adult trigeminal nerve and ganglion : 1 ) an alteration of the gross morphology of vibrissal nerves , 2 ) a significant reduction in the average number ( 85.4 % ) and diameter ( 32.6 % ) of myelinated , but not unmyelinated , follicle nerve axons , 3 ) a significant decrease in the average number ( 36.8 % ) of trigeminal ganglion cells innervating vibrissa follicles , 4 ) no significant change in the distribution of ganglion cell diameters , 5 ) an increase in peripheral branching ( 1.8-fold ) of these ganglion cell axons , and 6 ) an alteration of somatotopic order within the trigeminal ganglion .
