The author designed the apparatus which recorded the rotatory sensation in the pendular rotatory movement and investigated this sensation in normal and pathological cases.First, in normal cases the rotatory sensation was recorded as symmetrical curve in the pendular rotatory movement (amplitude 90°, period 20 sec.).The symmetricity of this sensation was always constant in the anterior, dorsal, left side and right side flexion of the head position.After the calorisation or Baranys test, the recorded rotatory sensation reveald 2 phases in the opposite direction, that is, peripheral I and central neural II.Secondly. in pathological cases which had the peripheral vestibular disturbances, the rotatory sensation to one side was dominant, so recorded curve revealed asymmetry.Its direction in most cases was coincident with the direction of the spontaneous nystagmus, if it existed.From the side-difference of the above mentioned record after the calorisation we could decide the difference of the labyrinth function.
