Sharply defined anatomic lesions of the brain stem have recently acquired a new interest in so far as they are now able to furnish us exact information as to the course of those fibers which come from the upper part of the mesencephalon and extend to the centrum ciliospinale. Irritation of these fibers produces psychic as well as reflex dilatation of the pupils. Information is also furnished regarding the path of those other fibers that transmit the irritation from the vestibular apparatus to the oculopontile nuclei. The following case is of interest in this connection.
