Fluid kinetics of endolymph during rotation.
Rotatory vestibular excitability is discussed on the basis of a fluid-mechanical theory. The principle of this theory, already described for caloric excitation, is that appropriate stimulus causes flows within the endolymph. Experimental and mathematical approaches indicate these flows to be essentially the same in caloric as in rotatory stimulation. The direction of a horizontal nystagmus is apparently determined by a circuit of endolymph in the lateral part of the ampulla.
