Abstract:
The posterior semicircular canal of the frog was stimulated by mechanical endolymphatic flow toward either an ampullofugal (excitatory) or ampullopetal (inhibitory) direction. The magnitudes of the responses as the cupula was moved to various positions were compared. When the same amount of stimulus was given in the same direction, the responses were equal, regardless of the initial position of the cupula.
