Experiments in pigeons , have demonstrated that the mechanical detachment of the cupula from the roof of the ampulla results in the clinical picture of a vestibular loss of function. This pulls the cupula and alters the firing rate of neurons (Herdman S. J., 2007)." Canalolithiasis is characterized by: -"Delay in onset of symptoms of vertigo 1 to 40 seconds (time needed for cupula to be deflected by endolymph) (Herdman S.
