“…However, it seems to us that certain differences in physical strength between the ampullopetal flow and the ampullofugal flow are related to Ewald's law besides the morphological polarization of sensory cells. Leiri (1927) thought that the endolymph flowed easily from the narrow canal to the wide utricle, but not so easily in the reverse direction. We confirmed Leiri's opinion by recording a pigeon's intracanalicular pressure change induced by rotatostimulation in both labyrinths (Hozawa et al, 1965).…”

Sixty-five guinea pigs were used to investigate the influence of rotatostimulations on the lateral crista ampullaris. After repeated turning stimulations with the cupulometric mode (the terminal turning velocity: 180"lsec) for 2 6 7 2 hours, the morphological changes in the crista ampullaris on the ampullopetal flow side were compared with those on the ampullofugal flow side by using scanning and transmission electron microscopy. Postrotatory nystagmus recorded by ENG during this experiment revealed the response decline phenomenon in all animals, and the caloric test performed after the rotatostimulation showed 'canal paresis' in the ear on the ampullopetal flow side. In a group stimulated for 24 hours, no particular damage on the crista ampllaris was noticed. However, in a group stimulated for 72 hours, local damage was dominant in the central part of the crista, which showed a tendency to extend towards the planum semilunatum according to an increment of changes. These findings were more remarkable on the ampullopetal flow side than on the ampullofugal flow side, suggesting the predominant effect of the ampullopetal endolymph flow in the lateral semicircular canal.
