A study of the rhythmic motions of the living cranium

This paper is intended to present the results of exploration of these three questions regarding an inherent motility of the cranium. Does such a motion really occur? Can it be mechanically recorded? If it exists, what is its relation to known physiologic functions? With regard to the first question, as to the existence of such a rhythmic motion, slower than and different from the thoracic respiratory rhythm, within the living cranium, those trained in skillful palpation of the human body have claimed for nearly 30 years that such inherent motility is detectable. The validity of the palpatory findings of persons with trained hands is, however, subject to question by those who lack such palpatory skill. The doubt is due primarily to the plausible hypothesis that the sense of touch will experience systematic tactile illusions when subjected to small cyclic motions.
