At a meeting of the Central Neuropsychiatric Association in Chicago on Sept. 27, 1930, a preliminary report was made on a group of studies outlined by Dr. Loyal Davis and Dr. Lewis J. Pollock of the motor responses resulting from neck and labyrinthine reflexes in man, elicited by movement of the head and by caloric and galvanic stimulation of the labyrinths.

This communication deals with an attempt to establish the constancy and pattern of the reaction in the limbs consequent to movement of the head and of another limb in normal persons.

Studies of postural reactions in man, aside from the earlier studies of Magnus and de Kleijn1 primarily on hydrocephalic and idiotic infants or children, have been reported by Walshe,2 Simons,3 Brain,4 and others. Walshe found evidence of the existence of tonic reflexes of the neck acting on the paralyzed limbs in patients with hemiplegia.
