INTERESTING observations in a case of bilateral complete paralysis of the tongue (panglossoplegia) were the occasion for these studies. New information resulting therefrom is presented concerning particular aspects of the neural and muscular mechanisms responsible for certain movements of the tongue and of the lips. On the basis of these findings in correlation with known anatomic factors differential topognosis of the lesion in instances of hypoglossal and/or facial nerve paralysis is discussed.
