Does sitting on a rotating stool temporarily cure sufferers of these
disorders?  If so, then the  vestibular stimulation is involved. If
not, then probably a direct temperature effect to the brain nearest
the auditory canal is involved. And the vestibular activation is a
complex interaction of ipsilateral and contralateral pathways.

Besides, I believe that cold water in the ear induces, not only
nystagmus, but dizzyness and nausea!
