motor corticotrigeminus fibers;difficulties in swallowing, of phonation, and of articulation from lesions of the cortico-nuclear fibers of the spinal vagus. As a result of the predominance of the antagonists of the sound side (left) in (a) and(6), there can be observed a deviation of the mouth (facial), and of the jaw (masticators)toward the left, a deviation of the tongue to the paralyzed side (action of sound genio-glossus) and in (b) further a conjugate deviation of the head and of the eyes toward theleft (action of the external branch of the spinal accessory and of the levorotory ocularfibers) and a deviation of uvula toward the left (spinal vagus). On the left side there is a direct paralysis of the third (III) nerve with ptosis, divergentstrabismus, with or without mydriasis and pupils which do not react either to light orconvergence, according to the grade of destruction of the root fibers of the oculomotorius(777).

ff-^i7/eC Fig. 197.—Anterior cephalic pontine syndrome. Hemiplegia of cerebral type due tothrombosis of the upper part of the basilar trunk. The lesion is unilateral, occupying thecephalad part of the pons, or the anterior portion of the right pons destroying there thecorticospinal pyramidal fibers, the corticonuclear fibers of the facial, the masticators,and the hypoglossal. It does not involve the tegmentum nor the root fibers of thecranial nerves. On the left side there is a crossed hemiplegia of the trunk and extremities with con-tractures and exaggeration of the reflexes. Left inferior facial hemiplegia, mild superiorhemifacial paresis, slight widening of the palpebral fissure, slight drooping of the externalborder of the left eyebrow, slight impairment of independent closure of the eyes; hemi-paresis of the masticators, especially of the internal pterygoid. Hemiparesis of thetongue. Integrity of electrical reactions. By reason of the predominance of the muscles on the sound si
