Within the substance of the pons, those fibres of the facial nervewhich are prolonged cephalad, decussate. The level of this decussationmay be designated by an imarjinary line, which shall connect the ap-parent oiigins of the fifth cranial nerves (Gubler). Lesions of the pons above the line of Gubler, which affect the facialfibres, produce facial paralysis on the side opposed to the lesion, and,when below that level, upon the same side as the so BVB Fig. —A Transverse Section Through the Pons, on a Level with the Roots op theSixth AND Seventh Cranial Nerves from a Nine Months Embryo.
