Under little influence of counter flow, thermal stimulus was applied to the partly isolated posterior semicircular canal of the bullfrog. Warming or cooling stimuli to either canal side or utricular side of the canal changed semicircular canal nerve activity. These results suggest that the changes in the endolymphatic density might be responsible for caloric nystagmus evoked in weightlessness.
