Abstract
A switching adapter that provides a rapid and convenient apparatus for selective recording of vertical eye movements with a single channel recorder in electronystagmograph apparatus. A number of single channel recorders are used in the field to observe the horizontal eye movements elicited by thermally induced vestibular unbalance. In certain types of pathological unbalances, vertical eye movement is also present, therefore, it is highly desirable to be able to also record the vertical eye movement. The switching adapter conveniently converts single channel recorders that are normally used for recording horizontal eye movement for recording vertical nystagmus.
