Central facial weakness due to medial medullary infarction: the course of facial corticobulbar fibres.
Two patients are reported with contralateral hemiparesis including a face of supranuclear type, caused by an infarct of the unilateral ventromedial part of the upper medulla. Data from these patients support the hypothesis that part of the corticobulbar fibres supplying the lower facial muscles descend ipsilaterally in the ventromedial part of the upper medulla and then, after decussation, ascend rostrally to the contralateral facial nucleus.
