Barbecue Rotation In Combination with Sinusoidal Rotation About a Vertical Axis A Preliminary Note

Abstract

The eye-movements caused by a combination of rotations about a cephalo-caudal horizontal axis and sinusoidally changing accelerations about a vertical axis were recorded. A mathemetical analysis of the spatial vector is given. The response is recorded by means of electro-nystagmography and analysed into an otolithic and a semicircular component. It appears that not only the left and the right labyrinth, but also in one single labyrinth the otoliths and the semicircular canals are stimulated differently by the same vector.
