Bárány’s method revolutionized understanding of the vestibular system, and spurred new experimental vestibular research, such as investigations into the structure of the semicircular canals, that was important for understanding posture and locomotion in animals and humans. As an example, semicircular canals are present in all vertebrates but vary in their form and structure depending on the species’ locomotor behaviour. Analysis of the fine structure of the inner ear of several mammalian species revealed that the size of the semicircular canals is correlated with the agility and range of the animal’s movements
