 Rebound the stagmas are another localizing the stagmas. Note how when the patient gazes to the right, small amplitude jerk the stagmas to the right can be seen. When gaze is shifted to forward gaze, the amplitude and the stagmas stays the same, but the direction shifts to left beating. Now the patient's in left gaze, left beating the stagmas are observed. When the patient shifts gaze to forward gaze, note how the direction of the stagmas will then change to right beating. This cycle can repeat itself indefinitely as long as gaze is shifted. The localizing value of rebound the stagmas concerns its relationship to disease and disorders of the cerebellum. It can be seen in degenerations of the cerebellum, infarction, demyelination. And what we're observing now is just a continuation of the previously mentioned cycle. Again, note how the direction of the stagmas changes.
